-As Unix Systems are becoming more and more popular to even beginners working with computer machines
-due to its advantages in regards of stability and functionality, most are somehow disappointed, because
-those applications don't have a consistent look and each one behaves different from another. With KDE,
-developers have an almost perfect way to create first-class applications for Unix desktop systems to get
-a wider user community by the mere quality their applications have to offer. Therefore, KDE becomes more
-and more popular as a base for programming design, and developers want to take advantage of the

-For making the best use of this programming handbook, we assume that you already know about the
-C++ programming language; if not, you should make yourself familiar with that first. Information about
-C++ is available through various sources either in printed form at your local bookstore or by tutorials
-found on the Internet. Knowledge about the design of Graphical User Interfaces is not required, as this
-handbook tries to cover the application design for KDE programs, which also includes an introduction into
-the Qt toolkit as well as the KDE libraries and the design of User Interfaces. Also, you should have made
-yourself comfortable with &tdevelop; by reading The User Manual to &tdevelop;, which contains a descriptive
-review of the functionality provided by the IDE.

-<title>The KDE and Qt Libraries</title>
-<para>
-The Norwegian company TrollTech (<ulink url="http://www.trolltech.com">http://www.trolltech.com</ulink>)
-provides a so-called GUI toolkit, named Qt. GUI means "Graphical User Interface", and therefore, Qt-based
-applications represent themselves with buttons, windows etc, allowing user input by visualizing the functions
-an application provides. Such a toolkit is needed for developing graphical applications that run on the X-Window
-interface on Unix Systems, because X does not contain a pre-defined user interface itself. Although other
-toolkits are also available to create User Interfaces, Qt offers some technical advantages that make
-application design very easy. Additionally, the Qt toolkit is also available for Microsoft Windows systems,
-which allows developers to provide their applications for both platforms.
-</para>
-<para>
-The KDE Team (<ulink url="http://www.kde.org">http://www.kde.org</ulink>) joined together with the goal
-to make using Unix Systems more friendly, and decided to use the Qt toolkit for the development of a window
-manager on X-Windows, plus a variety of tools included with the KDE packages. The K Desktop Environment
-therefore contains the window manager kwm, the file manager kfm and the launch panel kpanel as the main
-components plus a variety of first-class utilities and applications. After KDE was out, a lot of developers
-turned their eyes towards the new environment and what it has to offer them. The KDE libraries are providing
-essential methods and classes that make all applications designed with them look similar and consistent,
-so the user has the great advantage that he only has to get accustomed with an application's specific
-usage, not with handling dialogs or buttons. Also, KDE programs integrate themselves into the desktop and
-are able to interact with the file manager via drag'n drop, offer session management and many more, if all
-features offered by the KDE libraries are used. Both, the Qt toolkit and the KDE libraries, are implemented
-in the C++ programming language; therefore applications that make use of these libraries are also mostly
-written in C++. In the following chapter, we'll make a short trip through the libraries to see what already
-is provided and how Qt and TDE applications are created in general.

-<sect1 id="c2s1">
-<title>The Qt GUI Toolkit</title>
-<para>
-As said, the Qt library is a toolkit that offers graphical elements that are used for creating GUI
-applications and are needed for X-Window programming. Additionally, the toolkit offers:
-<itemizedlist>
-<listitem><para>A complete set of classes and methods ready to use even for non-graphical programming issues</para></listitem>
-<listitem><para>A good solution towards user interaction by virtual methods and the signal/slot mechanism</para></listitem>
-<listitem><para>A set of predefined GUI-elements, called "widgets", that can be used easily for creating the visible elements</para></listitem>
-<listitem><para>Additional completely pre-defined dialogs that are often used in applications such as progress and file dialogs</para></listitem>
-</itemizedlist>
-</para>
-<para>
-Therefore knowing the Qt classes is very essential, even if you only want to program KDE-applications.
-To have an impression on the basic concept how GUI-applications are constructed and compiled, we'll first
-have a look at a sample Qt-only program; then we'll extend it to a KDE program.
-</para>
-
-<sect2 id="c2s1s1">
-<title>The first Qt Application</title>
-<para>
-As usual, programs in C++ have to contain a <function>main()</function> function, which is the starting point for application
-execution. As we want them to be graphically visible in windows and offering user interaction,
-we first have to know, how they can show themselves to the user. For an example, we'll have a look
-at the first tutorial included with the Qt Online Reference Documentation and explain the basic execution
-steps; also why and how the application window appears:
-<programlisting>
-#include &lt;qapplication.h>
-#include &lt;qpushbutton.h>
-
-int main( int argc, char **argv )
-{
-QApplication a( argc, argv );
-
-QPushButton hello( "Hello world!", 0 );
-hello.resize( 100, 30 );
-
-a.setMainWidget( &amp;hello );
-hello.show();
-return a.exec();
-}
-</programlisting>
-</para>
-<para>
-This application merely paints a window containing a button with "Hello world" as its text. As for
-all Qt-based applications, you first have to create an instance of the class <classname>QApplication</classname>, represented by
-variable a.
-</para>
-<para>
-Next, the program creates an instance of the class <classname>QPushButton</classname> called hello, this will be the button.
-The constructor of hello gets a string as a parameter, which is the contents of the widget visible as
-the buttons text.
-</para>
-<para>
-Then the <methodname>resize()</methodname> method is called on the hello button. This changes the default size a widget
-(which is in this case the <classname>QPushButton</classname>) has when created to the length of 100 pixels and the height of
-30 pixels. Finally, the setMainWidget() method is called for a and the show() method for hello. The
-QApplication is finally executed by <methodname>a.exec()</methodname>, enters the main event loop and waits until it has to return
-an integer value to the overlaying Operating System signaling that the application is exited.
-</para>
-</sect2>
-
-<sect2 id="c2s1s2">
-<title>The Reference Documentation for Qt</title>
-<para>
-Now, let's have a quick look at the reference documentation of the Qt library. To do this, start
-&tdevelop; and select "Qt" from the tree in the Documentation tab. The documentation browser opens
-and shows you the start page of the Qt reference. This will be your first place to get information
-about Qt, it's classes and the available functions they provide. Also, the above program is the first
-that is included in the tutorials section. To get to the classes we want to have a look at,
-<classname>QApplication</classname> and <classname>QPushButton</classname>, select "Alphabetical Class List"
-and search for the according names. Follow either of them to have a look at the class documentation.
-</para>
-<para>
-Alternatively, you can use the online documentation from Trolltech's <ulink url="doc.trolltech.com">Qt Documentation</ulink>
-</para>
-<para>
-For <classname>QApplication</classname>, you will see the constructor and all other methods that this
-class provides. If you follow a link, you will get more information about the usage and meaning of the
-methods, which is very useful when you sometimes can't detect the correct use or want to have an example.
-This also counts for the KDE library documentation, which uses a similar documentation type; therefore
-this is almost all you have to know about using the class-references with the documentation browser.
-</para>
-<sect3 id="c2s1s2s1">
-<title>Interpretation of the Sample</title>
-<para>
-Starting with <classname>QApplication</classname>, you will find all the methods used in our first example:
-<itemizedlist>
-<listitem><para>the constructor <methodname>QApplication()</methodname></para></listitem>
-<listitem><para>the <methodname>setMainWidget()</methodname> method</para></listitem>
-<listitem><para>the <methodname>exec()</methodname> method</para></listitem>
-</itemizedlist>
-</para>
-<para>
-The interpretation why we use these methods is very simple:
-<orderedlist>
-<listitem><para>Create an instance of the class <classname>QApplication</classname> with the constructor,
-so we can make use of the GUI elements provided by Qt</para></listitem>
-<listitem><para>Create a widget which will be the contents of our program window</para></listitem>
-<listitem><para>Set the widget as the main widget for a</para></listitem>
-<listitem><para>Execute the a instance of <classname>QApplication</classname></para></listitem>
-</orderedlist>
-</para>
-<para>
-The second object of our program is the pushbutton, an instance of the class <classname>QPushButton</classname>.
-From the two constructors given to create an instance, we used the second: this accepts a text,
-which is the label contents of the button; here, it is the string "Hello world!". Then we called the
-<methodname>resize()</methodname> method to change the size of the button according to it's contents -
-the button has to be larger to make the string completely visible.
-</para>
-<para>
-But what about the <methodname>show()</methodname> method? Now, you see that like most other widgets,
-<classname>QPushButton</classname> is based on a single inheritance, the documentation says, Inherits
-<classname>QButton</classname>. Follow the link to the <classname>QButton</classname> class.
-This shows you a lot of other widgets that are inherited by <classname>QPushButton</classname>,
-which we'll use later to explain the signal/slot mechanism. Anyway, the <methodname>show()</methodname>
-method is not listed, therefore, it must be a method that is provided by inheritance as well. The class
-that <classname>QButton</classname> inherits is <classname>QWidget</classname>. Just follow the link
-again, and you will see a whole bunch of methods that the QWidget class provides; including
-the <methodname>show()</methodname> method. Now we understand what was done in the sample with the button:
-<orderedlist>
-<listitem><para>Create an instance of <classname>QPushButton</classname>, use the second constructor to set the button text</para></listitem>
-<listitem><para>Resize the widget to its contents</para></listitem>
-<listitem><para>Set the widget as the main widget of the <classname>QApplication</classname> instance a</para></listitem>
-<listitem><para>Tell the widget to display itself on the screen by calling <methodname>show()</methodname>, an inherited method from <classname>QWidget</classname></para></listitem>
-</orderedlist>
-</para>
-<para>
-After calling the <methodname>exec()</methodname> method, the application is visible to the user,
-showing a window with the button showing "Hello world!". Note: GUI programs behave somewhat differently
-than procedural applications. The main thing here is that the application enters a so-called
-"main event loop". This means that the program has to wait for user actions and then react to it, also
-that for a Qt application, the program has to be in the main event loop to start the event handling.
-The next section tells you in short what this means to the programmer and what Qt offers to process
-user events.
-</para>
-<note><para>
-For already advanced users: The button has no parent declared in the constructor, therefore it
-is a top-level widget alone and runs in a local event loop which doesn't need to wait for the main
-event loop. See the QWidget class documentation and The KDE Library Reference Guide</para>
-</note>
-
-</sect3>
-</sect2>
-
-<sect2 id="c2s1s3">
-<title>User Interaction</title>
-<para>
-After reading the last sections, you should already know:
-<itemizedlist>
-<listitem><para>What the Qt-library provides in terms of GUI applications</para></listitem>
-<listitem><para>How a program using Qt is created and</para></listitem>
-<listitem><para>Where and how to find information about classes that you want to use with the documentation browser</para></listitem>
-</itemizedlist>
-</para>
-<para>
-Now we'll turn to give the application "life" by processing user events. Generally, the user has two ways
-to interact with a program: the mouse and the keyboard. For both ways, a graphical user interface has to
-provide methods that detect actions and methods that do something as a reaction to these actions.
-</para>
-<para>
-The Window system therefore sends all interaction events to the according application. The
-<classname>QApplication</classname> then sends them to the active window as a <classname>QEvent</classname>
-and the widgets themselves have to decide what to do with them. A widget receives the event and processes
-<methodname>QWidget::event(QEvent*)</methodname>, which then decides which event has been executed
-and how to react; <methodname>event()</methodname> is therefore the main event handler. Then,
-the <methodname>event()</methodname> method passes the event to so-called event filters
-that determine what happened and what to do with the event. If no filter signs responsible for the
-event, the specialized event handlers are called. Thereby we can decide between:

-Note that all event functions are virtual and protected; therefore you can re-implement the events
-that you need in your own widgets and specify how your widget has to react. <classname>QWidget</classname>
-also contains some other virtual methods that can be useful in your programs; anyway, it is sufficient
-to know about <classname>QWidget</classname> very well.

-<sect2 id="c1s2s4">
-<title>Object Interaction by Signals and Slots</title>
-<para>
-Now we're coming to the most obvious advantages of the Qt toolkit: the signal/slot mechanism.
-This offers a very handy and useful solution to object interaction, which usually is solved by
-callback functions for X-Window toolkits. As this communication requires a strict programming and
-sometimes makes user interface creation very difficult (as referred by the Qt documentation and explained
-in Programming with Qt by K.Dalheimer), Troll Tech invented a new system where objects can emit signals
-that can be connected to methods declared as slots. For the C++ part of the programmer, he only has to know
-some things about this mechanism:
-<itemizedlist>
-<listitem><para>
-the class declaration of a class using signals/slots has to contain the Q_OBJECT macro at the beginning
-(without a semicolon); and have to be derved from the <classname>QObject</classname> class
-</para></listitem>
-<listitem><para>
-a signal can be emitted by the keyword emit, e.g. emit signal(parameters); from within any member function
-of a class that allows signals/slots
-</para></listitem>
-
-<listitem><para>
-all signals used by the classes that are not inherited have to be added to the class declaration by a
-signals section
-</para></listitem>
-<listitem><para>
-all methods that can be connected with a signal are declared in sections with the additional keyword slot,
-e.g. public slots: within the class declaration
-</para></listitem>
-<listitem><para>
-the meta-object compiler moc has to run over the header file to expand the macros and to produce the
-implementation (which is not necessary to know). The output files of moc are compiled also by the C++ compiler.
-</para></listitem>
-</itemizedlist>
-</para>
-<para>
-Another way to use signals without deriving from <classname>QObject</classname> is to use the
-<classname>QSignal</classname> class- see the reference documentation for more information and example
-usage. In the following, we assume you're deriving from <classname>QObject</classname>.
-</para>
-<para>
-This way, your class is able to send signals anywhere and to provide slots that signals can connect
-to. By using the signals, you don't have to care about who's receiving it- you just have to emit the
-signal and whatever slot you want to connect to it can react to the emission. Also the slots can be used
-as normal methods during implementation.
-</para>
-<para>
-Now, to connect a signal to a slot, you have to use the <methodname>connect()</methodname> methods that
-are provided by <classname>QObject</classname> or, where available, special methods that objects provide
-to set the connection for a certain signal.
-</para>
-
-<sect3 id="c1s2s4s1">
-<title>Sample Usage</title>
-<para>
-To explain the way how to set up object-interaction, we'll take our first example again and extend it by a

-</para>
-<para>
-You see, the only addition to give the button more interaction is to use a <methodname>connect()
-</methodname> method: <methodname>connect(&amp;hello, SIGNAL( clicked() ), &amp;a, SLOT( quit() ))</methodname>;
-is all you have to add. What is the meaning now? The class declaration of QObject says about the
-<methodname>connect()</methodname> method:
-</para>
-<para><methodname>
-bool connect ( const QObject * sender, const char * signal, const QObject * receiver, const char * member )
-</methodname></para>
-<para>
-This means you have to specify a <classname>QObject</classname> instance pointer that is the sender
-of the signal, meaning that it can emit this signal as first parameter; then you have to specify the signal
-that you want to connect to. The last two parameters are the receiver object that provides a slot, followed
-by the member function which actually is the slot that will be executed on signal emission.
-</para>
-<para>
-By using signals and slots, your program's objects can interact with each other easily without explicitly
-depending on the type of the receiver object. You will learn more about using this mechanism for productive
-usage later in this handbook. More information about the Signals/Slot mechanism can also be found in

-<title>Example KDE Application</title>
-<para>
-In the following, you will see that writing a KDE application is not much more difficult than a
-Qt application. For the use of KDE's features, you just have to use some other classes, and you're almost
-done. As an example, we'll discuss the changed version of the Qt example from above:
-<programlisting>
-#include &lt;tdeapplication.h>
-#include &lt;qpushbutton.h>
-
-int main( int argc, char **argv )
-{
-TDEApplication a( argc, argv );
-
-QPushButton hello( "Hello world!", 0 );
-hello.resize( 100, 30 );
-
-a.setTopWidget( &amp;hello );
-
-QObject::connect(&amp;hello, SIGNAL( clicked() ), &amp;a, SLOT( quit() ));
-
-hello.show();
-return a.exec();
-}
-</programlisting>
-</para>
-<para>
-You see that first we have changed from <classname>QApplication</classname> to <classname>TDEApplication
-</classname>. Further, we had to change the previously used <methodname>setMainWidget()</methodname> method
-to <methodname>setTopWidget</methodname>, which <classname>TDEApplication</classname> uses to set the main
-widget. That's it! Your first KDE application is ready - you only have to tell the compiler the KDE
-include path and the linker to link in the tdecore library with -ltdecore.
-</para>
-<para>
-As you now know what at least the <function>main()</function> function provides generally and how an
-application gets visible and allows user and object interaction, we'll go on with the next chapter,
-where our first application is made with &tdevelop;. There you can also test everything which was
-mentioned before and see the effects.
-</para>
-<para>
-What you should have looked into additionally until now is the reference documentation for Qt,
-especially the <classname>QApplication</classname>, <classname>QWidget</classname> and <classname>QObject
-</classname> class and the tdecore library documentation for the <classname>TDEApplication</classname> class.
-The <ulink url="developer.kde.org/documentation/library/libraryref.html">KDE Library Reference handbook</ulink>

-<title>The source skeleton</title>
-<para>
-To conceptualize how a KDE application works, we'll first have a very close look at the source
-skeleton already provided by the Application Wizard. As we already saw, we're having a set of source
-and header files that build the initial code for the application and make it ready-to-run. Therefore,
-the easiest way to explain the code is to follow the implementation line by line as it is processed
-during executing the program until it enters the main event loop and is ready to accept user input.
-Then, we'll have a look at the functionality that enables user interaction and how certain things work.
-This is probably the best way to explain the framework and, as it is similar to almost all KDE
-applications, will enable you to read source codes from other projects as well; additionally, you will
-know where to change what part of the code to make your applications behave the way they are designed for.

-of a document and provides methods to manipulate the document contents. This can be done by the user via
-the events he emits by the keyboard or the mouse; more complex operations are often processed by toolbars
-and menubars which interact with the view and the document. The statusbar then provides information about
-the document, view or application status. As an example, we look at how an editor is constructed and where
-we can find which part.
-</para>
-<para>
-An editor generally is supposed to provide an interface to view and/or change the contents of a text
-document for the user. If you start Kate, you see the visual interface as the following:
-<itemizedlist>
-<listitem><para>
-The menubar: providing complex operations as well as opening, saving and closing files and
-exiting the application.
-</para></listitem>
-<listitem><para>
-The toolbar: offers icons which allow quicker access for most needed functions,
-</para></listitem>
-<listitem><para>
-The statusbar: displays the status of the cursor position by the current row and column,
-</para></listitem>
-<listitem><para>
-The view in the center of the window, displaying a document and offering a cursor connected to
-the keyboard and the mouse to operate on the data.
-</para></listitem>
-</itemizedlist>
-</para>
-<para>
-Now it's easy to understand that a view is the most unique part of the application and the design
-of the view decides about the usability and acceptability of an application. This means that one of
-the first steps in development is to determine the purpose of the application and what kind of view
-design would match best to allow any user to work with the application with a minimum of work
-learning how to handle the user interface.
-</para>
-<para>
-For some purposes like text editing and displaying HTML files, views are provided by the Qt and KDE
-libraries; we will discuss certain aspects of these high-level widgets in the next section.
-But for most applications new widgets have to be designed and implemented. It is that what makes a
-programmer also a designer and where his abilities on creativity are asked. Nevertheless, you should
-watch for intuitivity first. Remember, a lot of users won't accept an application that isn't:
-<itemizedlist>
-<listitem><para>
-graphically nice.
-</para></listitem>
-<listitem><para>
-offering a lot of features
-</para></listitem>
-<listitem><para>
-easy to handle
-</para></listitem>
-<listitem><para>
-fast to learn how to use it
-</para></listitem>
-</itemizedlist>
-</para>
-<para>
-Needless to say that stability is a major design goal. Nobody can prevent bugs, but a minimum can
-be reached at least by clever design goals and wide use of object-oriented design. C++ makes programming
-a joy if you know how to exploit it's capabilities- inheritance, information hiding and reusablitity of
-already existing code.
-</para>
-<para>
-When creating a KDE or Qt project, you always have to have a view that inherits QWidget, either by
-direct inheritance or because the library widget you want to use inherits QWidget. Therefore, the
-Application Wizard already constructed a view that is an instance of a class yourappView, which
-inherits QWidget already.
-</para>
-<para>
-This chapter therefore describes how to use library widgets for creating views of KDE or
-Qt applications that are generated with &tdevelop;, then we look at the libraries and what kind of
-views are already offered.
-</para>
-</sect1>
-<sect1 id="c4s2">
-<title>Using Library Views</title>
-<para>
-When your application design has been set up, you first should look for already existing code that
-will make your life a lot easier. A part of this search is to look for a widget that can be used as
-a view or at least as a part of it; either directly or by inheritance. The KDE and Qt libraries already
-contain a set of widgets that can be used for this purpose. To use them, you have two options:
-<orderedlist>
-<listitem><para>
-Remove the new view class and create an instance of a library widget; then set this as the view,
-</para></listitem>
-<listitem><para>
-Change the inheritance of the provided view class to the class of the library widget to use.
-</para></listitem>
-</orderedlist>
-</para>
-<para>
-In either way, it is important to know that if the application framework is currently not linked
-against the library that contains the widget, the linker will fail. After you decided to use a
-certain widget, look for the library to link to; then open "Project"->"Options" from the &tdevelop;
-menubar. Switch to the "Linker Options" page and look for the checkmarks indicating the libraries
-that are currently used. If the library of your view widget is already checked, you can leave the
-project options untouched and start doing the necessary changes due to your choice. If not, and the
-linker options offer to add the library by a check box, check it and press "OK" to leave the project
-options dialog again. In any other case, add the library in the edit line below with the -l option.
-For libraries that your application has to search for before preparing the Makefiles by the
-configure script on the end-user machine, add the according search macro to the configure.in file
-located at the root directory of your project and add the macro to the edit line. Mind that you have
-to run "Build"->"Autoconf and automake" and "Build"->"Configure" before the Makefiles contain the
-correct expansion for the library macro.
-</para>
-<para>
-Also, if the include files for the library to add are not in the current include path
-(which can be seen by the -I options in the output window on "Make"), you have to add the path to the
-Project Options dialog -"Compiler Options" page with the -I option or the according automake macro at
-the edit line for "Additional Options".
-</para>
-<sect2 id="c4s3s1">
-<title>Qt Views</title>
-<para>
-Looking at the first page of the Qt online documentation, you will find a link to
-"Widget Screenshots" where you can have a look at how the widgets Qt contains look like.
-These are ready to use and can be combined together to form complex widgets to create application
-views or dialogs. In the following, we'll discuss some of these which are very usable for creating
-application views, but keep in mind that the KDE libraries sometimes contain other widgets for the
-same purpose; those will be reviewed in the next section.
-</para>
-<para>
-Here are a set of hints for what purpose you could use which Qt component:
-<orderedlist>
-<listitem><para>
-If your view area isn't big enough to display all your data, the user must be enabled to scroll
-over the document with bars on the left and bottom of the view. For this, Qt provides the class
-<classname>QScrollView</classname>, which offers a scrollable child area. As explained, you could
-inherit your own widget from <classname>QScrollView</classname> or use an instance to manage your
-document's view widget.
-</para></listitem>
-<listitem><para>
-to create a ScrollView yourself, inherit the View widget from <classname>QWidget</classname>
-and add vertical and horizontal <classname>QScrollBars </classname>.
-(This is done by KDE`s TDEHTMLView widget.)
-</para></listitem>
-<listitem><para>
-For text processing, use <classname>QTextEdit</classname>. This class provides a complete
-text editor widget that is already capable to cut, copy and paste text and is managed by a scrollview.
-</para></listitem>
-<listitem><para>
-Use <classname>QTable</classname> to display data that is arranged in a table.
-As <classname>QTable</classname> is managed by scrollbars as well, it offers a good solution for
-table calculation applications.
-</para></listitem>
-<listitem><para>
-To display two different widgets or two widget instances at the same time, use <classname>QSplitter
-</classname>. This allows to tile views by horizontal or vertical dividers.
-KMail is a good example what this would look like- the main view is separated by a
-splitter vertically, the right window then is divided again horizontally.
-</para></listitem>
-<listitem><para>
-<classname>QListView</classname> displays information in a list and tree.
-This is useful for creating file trees or any other hierarchical information you want to interact with.
-</para></listitem>
-</orderedlist>
-</para>
-<para>
-You see that Qt alone offers a whole set of widgets which are ready to use so you don't have to invent
-new solutions if these match your needs. The sideffect when using standard widgets is that users already
-know how to handle them and only have to concentrate on the displayed data.
-</para>
-</sect2>
-<sect2 id="c4s3s2">
-<title>KDE Views</title>
-<para>
-The KDE libraries were invented to make designing applications for the K Desktop Environment easier
-and capable of more functionality than what Qt alone is offering. The tdeui library offers:
-<orderedlist>
-<listitem><para>
-TDEListView: a more powerful version of <classname>QListView</classname>
-</para></listitem>
-<listitem><para>
-TDEIconView: a graphical viewer of icon files
-</para></listitem>
-</orderedlist>
-</para>
-<para>
-The tdehtml library, on the other hand, offers a complete HTML-interpreting widget that is ready to use.
-It is scrollable already, so you don't even have to take care for that. A possible use could be to
-integrate it as a preview widget for an HTML editor; used by applications such as Konqueror to display HTML files.

-<title>Configuring Menubars and Toolbars</title>
-<sect1 id="c5s1">
-<title>Introduction</title>
-<para>
-Menubars and toolbars are one of the most important parts of an application to provide methods to
-work with a document structure. As a general rule, you should make all functions available by the menubar.
-Those methods that should not be available at a current stage of the application process should be
-disabled.
-</para>
-<para>
-Further, an application can only contain one menubar, but several toolbars.
-Toolbars on the other hand should contain only the most frequently used commands by pixmap
-icons or provide quick access methods like combos to select values.
-</para>
-</sect1>
-<sect1 id="c5s2">
-<title>How does it work?</title>
-<para>
-Our application inherits the <classname>TDEMainWindow</classname> class, which automatically handles creating
-a menu bar and tool bars for us. In the <methodname>KScribble::setupActions()</methodname> method there is
-a call to <methodname>TDEMainWindow::createGUI()</methodname>. This method loads a resource file, in this
-case kscribbleui.rc, to initialize menus at startup. Note that kscribbleui.rc is listed as one of the
-project files in the Automake Manager. Opening that file up reveals this:
-<programlisting>
-1 &lt;!DOCTYPE kpartgui SYSTEM "kpartgui.dtd">
-2 &lt;kpartgui name="kscribble" version="1">
-3 &lt;MenuBar>
-4 &lt;Menu name="custom">&lt;text>C&amp;ustom&lt;/text>
-5 &lt;Action name="custom_action" />
-6 &lt;/Menu>
-7 &lt;/MenuBar>
-8 &lt;/kpartgui>
-</programlisting>
-</para>
-<para>
-Explanation...
-</para>
-<para>
-Another way to modify the contents of the menu and tool bars is to directly manipulate them through the
-methods provided by their class. For example, the <methodname>menuBar()</methodname> method returns the
-<classname>KMenuBar</classname> widget that the menubar for our program. Looking at the documentation for
-<classname>KMenuBar</classname> and its inheritor class <classname>QMenuBar</classname>, you will find
-a large number of <methodname>insertItem()</methodname> methods which allow you to add items to the
-menu bar.
-</para>
-<para>
-<classname>TDEMainWindow</classname>'s methods <methodname>statusBar()</methodname> and <methodname>
-toolBar()</methodname> will also provide you with applicable widgets.
-</para>
-</sect1>
-<sect1 id="c5s3">
-<title>Keyboard Accelerator Configuration</title>
-<para>
-A very professional thing you should always add to your application are keyboard accelerators.
-Those are mainly used by experienced users that want to work fast with their applications and
-are willing to learn shortcuts. For this, the KDE libraries provide the class <classname>
-TDEAction</classname>, which provides the keyboard accelerator keys and access to global configured
-standard keyboard accelerators.
-</para>
-<para>
-By default, frame applications generated by &tdevelop; only use standard keyboard accelerators
-such as F1 for accessing online-help, Ctrl+N for New File etc.
-</para>
-<para>
-If your application contains a lot of accelerators, you should make them configurable
-by an Options-menu; either it could be combined with other application configuration in a QWidget
-or stand alone. The KDE library already provides a <classname>KKeyChooser</classname>
-for use in tab dialogs, whereas <classname>KKeyDialog</classname> provides a ready-to use
-key-configuration dialog.

-<title>Help Functions</title>
-<sect1 id="c8s1">
-<title>Introduction</title>
-<para>
-A very important part of the development process is to provide help functionality to the user
-wherever possible. Most developers tend to delay this, but you should remember that a normal user
-isn't necessarily a Unix expert. He may come from the the dark side of computer software usage offering
-all sweets that a user may need to work himself into using an application even without ever touching the
-manuals. Therefore, the KDE and Qt library provide all means usually considered making an application
-professional in the eyes of the normal user by help functions that are ready to use.
-Within the application, those are:</para>
-<itemizedlist>
-<listitem><para>Tool-Tips</para></listitem>
-<listitem><para>Statusbar help</para></listitem>
-<listitem><para>What's this...? buttons</para></listitem>
-</itemizedlist>
-<para>
-Additionally, the application should provide means to access a HTML-based online manual directly
-using the standard help key F1. This context based help system is provided automatically through the
-<classname>TDEMainWindow</classname> class, though as the author you must provide the content.
-</para>
-<para>
-As &tdevelop; also offers all types of help as well as the KDE framework generated by the
-application wizard already contains support for this, this chapter will help you find out where
-and how to add your help functionality. </para>
-<para>
-During the development of your application you should try to be consistent whatever you're doing;
-therefore you should do the necessary steps directly while extending the code. This will prevent you
-from diving into the code again and figuring out what your application does or what you intended by
-certain parts of the code.
-</para>
-</sect1>
-
-<sect1 id="c8s2">
-<title>Tool-Tips</title>
-<para>
-A very easy means of providing help are tool-tips. Those are small help messages popping up while
-the user moves the mouse over a widget that provides a tool-tip and disappears when the mouse moves away.
-The most popular usage of tool-tips is made in toolbars where your tool-tips should be kept as small
-as possible because toolbars can be configured to display their contents in various ways:
-either displaying the button, button with text on the right, button with text below, text only.
-This possibility should be made configurable by the user, but isn't a must-be. The text is shown
-as a tool-tip anyway and a toolbar usually consists of buttons and other widgets like lineedits and
-combo boxes. For a complete reference, see the <classname>TDEToolBar</classname> class reference located
-in the tdeui library.
-</para>
-<para>
-As an example, we have a look at the "New File" button in a generic application:
-</para>
-<para>
-There, the part i18n("New File") provides a tool-tip message. It is enclosed by the i18n()
-macro provided by kapp.h to translate the tool-tip towards the currently selected language.
-</para>
-<para>
-Tool-tips can also be added to any custom widget by using the <classname>QToolTip</classname>
-provided by Qt. An example of that would be:
-</para>
-</sect1>
-<sect1 id="c8s3">
-<title>Extending the Statusbar</title>
-<para>
-As the applications that inherit <classname>TDEMainWindow</classname> contain a statusbar as well,
-it also offers a set of statusbar messages already for all menu and toolbar items. A statusbar
-help message is a short message that extends the meaning of a tool-tip or can be seen as a replacement
-for a tool-tip over menubar items and is (as the name suggests) displayed in the statusbar when the user
-enters a menu and highlights the menu entry.
-</para>
-</sect1>
-<sect1 id="c8s4">
-<title>The <guibutton>What's This...?</guibutton> Button</title>
-<para>
-The <guibutton>What's This...?</guibutton> button provides help windows with the intention
-that the user wants to get help about a certain widget within the working view or a toolbar item.
-It is placed in the toolbar and gets activated once the user hits the button. The cursor changes
-to an arrow cursor with a question mark like the button itself looks like. The the user can press on
-a visible widget item and gets a help window. As an exercise, you could try this behavior with the
-<guibutton>What's this...?</guibutton> button within &tdevelop;.
-</para>
-<para>
-To add the What's This...? help to one of your widgets, use the static method
-<methodname>QWhatsThis::add(QWidget *widget, const QString &amp;text)</methodname>

-all &tdevelop; projects contain a pre-build handbook that can be easily adapted;
-therefore fulfiling another goal of KDE: providing enough online-help to support users that
-are not familiar with an application. This chapter therefore introduces you on how to extend
-the provided documentation template and what you have to do to make it available to the user.

-KDE-library documentation, also your application frameworks are already documented. To work yourself
-into the provided code, it would be a good start to read the included documentation online.

-i18n is an internationalization system that is used to offer internationalized versions of an
-application or project. The difficulty with writing applications is that they only support the
-language they originally are composed with; visually this can be seen on labels, menu entries and the
-like. The goal of the internationalization is to provide applications and library functions in the
-language of the user; therefore enabling users that are not native speakers the original language to make
-use of the provided functionality and feel more comfortable.
