provides a main application window, +with a menu bar, dock windows (e.g. for toolbars), and a status +bar. +<p> + +<p> Main windows are most often used to provide menus, toolbars and a +status bar around a large central widget, such as a text edit, +drawing canvas or <a href="tqworkspace.html">TQWorkspace</a> (for MDI applications). TQMainWindow +is usually subclassed since this makes it easier to encapsulate +the central widget, menus and toolbars as well as the window's +state. Subclassing makes it possible to create the slots that are +called when the user clicks menu items or toolbar buttons. You can +also create main windows using <a href="designer-manual.html">TQt + Designer</a>. We'll briefly review adding menu items and +toolbar buttons then describe the facilities of TQMainWindow +itself. +<p> <pre> + TQMainWindow *mw = new TQMainWindow; + <a href="tqtextedit.html">TQTextEdit</a> *edit = new <a href="tqtextedit.html">TQTextEdit</a>( mw, "editor" ); + edit-><a href="tqwidget.html#setFocus">setFocus</a>(); + mw-><a href="tqwidget.html#setCaption">setCaption</a>( "Main Window" ); + mw-><a href="#setCentralWidget">setCentralWidget</a>( edit ); + mw-><a href="tqwidget.html#show">show</a>(); + </pre> + +<p> TQMainWindows may be created in their own right as shown above. +The central widget is set with <a href="#setCentralWidget">setCentralWidget</a>(). Popup menus can +be added to the default menu bar, widgets can be added to the +status bar, toolbars and dock windows can be added to any of the +dock areas. +<p> + +<pre> ApplicationWindow *mw = new ApplicationWindow(); + mw-><a href="tqwidget.html#setCaption">setCaption</a>( "TQt Example - Application" ); + <a name="x2115"></a> mw-><a href="tqwidget.html#show">show</a>(); +</pre> +<p> In the extract above ApplicationWindow is a subclass of +TQMainWindow that we must write for ourselves; this is the usual +approach to using TQMainWindow. (The source for the extracts in +this description are taken from <a href="simple-application-example.html">application/main.cpp</a>, <a href="simple-application-example.html">application/application.cpp</a>, <a href="tqaction-application-example.html">action/main.cpp</a>, and <a href="tqaction-application-example.html">action/application.cpp</a> ) +<p> When subclassing we add the menu items and toolbars in the +subclass's constructor. If we've created a TQMainWindow instance +directly we can add menu items and toolbars just as easily by +passing the TQMainWindow instance as the parent instead of the <em>this</em> pointer. +<p> + +<pre> <a href="tqpopupmenu.html">TQPopupMenu</a> * help = new <a href="tqpopupmenu.html">TQPopupMenu</a>( this ); + <a href="#menuBar">menuBar</a>()->insertItem( "&Help", help ); + + help-><a href="tqmenudata.html#insertItem">insertItem</a>( "&About", this, TQ_SLOT(about()), Key_F1 ); +</pre> +<p> Here we've added a new menu with one menu item. The menu has been +inserted into the menu bar that TQMainWindow provides by default +and which is accessible through the <a href="#menuBar">menuBar</a>() function. The slot +will be called when the menu item is clicked. +<p> + +<pre> <a href="tqtoolbar.html">TQToolBar</a> * fileTools = new <a href="tqtoolbar.html">TQToolBar</a>( this, "file operations" ); + fileTools-><a href="tqtoolbar.html#setLabel">setLabel</a>( "File Operations" ); +</pre><pre> TQToolButton * fileOpen + = new <a href="tqtoolbutton.html">TQToolButton</a>( openIcon, "Open File", <a href="tqstring.html#TQString-null">TQString::null</a>, + this, TQ_SLOT(choose()), fileTools, "open file" ); +</pre> +<p> This extract shows the creation of a toolbar with one toolbar +button. TQMainWindow supplies four dock areas for toolbars. When a +toolbar is created as a child of a TQMainWindow (or derived class) +instance it will be placed in a dock area (the <a href="ntqt.html#Dock-enum">Top</a> dock area by +default). The slot will be called when the toolbar button is +clicked. Any dock window can be added to a dock area either using +<a href="#addDockWindow">addDockWindow</a>(), or by creating a dock window with the TQMainWindow +as the parent. +<p> + +<pre> e = new <a href="tqtextedit.html">TQTextEdit</a>( this, "editor" ); + e-><a href="tqwidget.html#setFocus">setFocus</a>(); + <a href="#setCentralWidget">setCentralWidget</a>( e ); + <a href="#statusBar">statusBar</a>()->message( "Ready", 2000 ); +</pre> +<p> Having created the menus and toolbar we create an instance of the +large central widget, give it the focus and set it as the main +window's central widget. In the example we've also set the status +bar, accessed via the <a href="#statusBar">statusBar</a>() function, to an initial message +which will be displayed for two seconds. Note that you can add +additional widgets to the status bar, for example labels, to show +further status information. See the <a href="tqstatusbar.html">TQStatusBar</a> documentation for +details, particularly the addWidget() function. +<p> Often we want to synchronize a toolbar button with a menu item. +For example, if the user clicks a 'bold' toolbar button we want +the 'bold' menu item to be checked. This synchronization can be +achieved automatically by creating actions and adding the actions +to the toolbar and menu. +<p> + +<pre> <a href="tqaction.html">TQAction</a> * fileOpenAction; +</pre><pre> fileOpenAction = new <a href="tqaction.html">TQAction</a>( TQPixmap( fileopen ), "&Open...", + CTRL+Key_O, this, "open" ); + <a href="tqobject.html#connect">connect</a>( fileOpenAction, TQ_SIGNAL( <a href="tqaction.html#activated">activated</a>() ) , this, TQ_SLOT( choose() ) ); +</pre> +<p> Here we create an action with an icon which will be used in any +menu and toolbar that the action is added to. We've also given the +action a menu name, '&Open', and a keyboard shortcut. The +connection that we have made will be used when the user clicks +either the menu item <em>or</em> the toolbar button. +<p> + +<pre> <a href="tqpopupmenu.html">TQPopupMenu</a> * file = new <a href="tqpopupmenu.html">TQPopupMenu</a>( this ); + <a href="#menuBar">menuBar</a>()->insertItem( "&File", file ); +</pre><pre> fileOpenAction-><a href="tqaction.html#addTo">addTo</a>( file ); +</pre> +<p> The extract above shows the creation of a popup menu. We add the +menu to the TQMainWindow's menu bar and add our action. +<p> + +<pre> <a href="tqtoolbar.html">TQToolBar</a> * fileTools = new <a href="tqtoolbar.html">TQToolBar</a>( this, "file operations" ); + fileTools-><a href="tqtoolbar.html#setLabel">setLabel</a>( "File Operations" ); + fileOpenAction-><a href="tqaction.html#addTo">addTo</a>( fileTools ); +</pre> +<p> Here we create a new toolbar as a child of the TQMainWindow and add +our action to the toolbar. +<p> We'll now explore the functionality offered by TQMainWindow. +<p> The main window will take care of the dock areas, and the geometry +of the central widget, but all other aspects of the central widget +are left to you. TQMainWindow automatically detects the creation of +a menu bar or status bar if you specify the TQMainWindow as parent, +or you can use the provided <a href="#menuBar">menuBar</a>() and <a href="#statusBar">statusBar</a>() functions. +The functions menuBar() and statusBar() create a suitable widget +if one doesn't exist, and update the window's layout to make +space. +<p> TQMainWindow provides a <a href="tqtooltipgroup.html">TQToolTipGroup</a> connected to the status bar. +The function <a href="#toolTipGroup">toolTipGroup</a>() provides access to the default +TQToolTipGroup. It isn't possible to set a different tool tip +group. +<p> New dock windows and toolbars can be added to a TQMainWindow using +<a href="#addDockWindow">addDockWindow</a>(). Dock windows can be moved using <a href="#moveDockWindow">moveDockWindow</a>() +and removed with <a href="#removeDockWindow">removeDockWindow</a>(). TQMainWindow allows default +dock window (toolbar) docking in all its dock areas (<a href="ntqt.html#Dock-enum">Top</a>, <a href="ntqt.html#Dock-enum">Left</a>, <a href="ntqt.html#Dock-enum">Right</a>, <a href="ntqt.html#Dock-enum">Bottom</a>). You can use <a href="#setDockEnabled">setDockEnabled</a>() to +enable and disable docking areas for dock windows. When adding or +moving dock windows you can specify their 'edge' (dock area). The +currently available edges are: <a href="ntqt.html#Dock-enum">Top</a>, <a href="ntqt.html#Dock-enum">Left</a>, <a href="ntqt.html#Dock-enum">Right</a>, <a href="ntqt.html#Dock-enum">Bottom</a>, <a href="ntqt.html#Dock-enum">Minimized</a> (effectively a 'hidden' dock area) and <a href="ntqt.html#Dock-enum">TornOff</a> (floating). See <a href="ntqt.html#Dock-enum">TQt::Dock</a> for an explanation of these +areas. Note that the *ToolBar functions are included for backward +compatibility; all new code should use the *DockWindow functions. +TQToolbar is a subclass of <a href="ntqdockwindow.html">TQDockWindow</a> so all functions that work +with dock windows work on toolbars in the same way. +<p> <a name="dwm"></a> +If the user clicks the close button, then the dock window is +hidden. A dock window can be hidden or unhidden by the user by +right clicking a dock area and clicking the name of the relevant +dock window on the pop up dock window menu. This menu lists the +names of every dock window; visible dock windows have a tick +beside their names. The dock window menu is created automatically +as required by <a href="#createDockWindowMenu">createDockWindowMenu</a>(). Since it may not always be +appropriate for a dock window to appear on this menu the +<a href="#setAppropriate">setAppropriate</a>() function is used to inform the main window +whether or not the dock window menu should include a particular +dock window. Double clicking a dock window handle (usually on the +left-hand side of the dock window) undocks (floats) the dock +window. Double clicking a floating dock window's titlebar will +dock the floating dock window. (See also +<a href="#DockWindows-enum">TQMainWindow::DockWindows</a>.) +<p> Some functions change the appearance of a TQMainWindow globally: +<ul> +<li> <a href="ntqdockwindow.html#setHorizontalStretchable">TQDockWindow::setHorizontalStretchable</a>() and +<a href="ntqdockwindow.html#setVerticalStretchable">TQDockWindow::setVerticalStretchable</a>() are used to make specific dock +windows or toolbars stretchable. +<li> <a href="#setUsesBigPixmaps">setUsesBigPixmaps</a>() is used to set whether tool buttons should +draw small or large pixmaps (see <a href="tqiconset.html">TQIconSet</a> for more information). +<li> <a href="#setUsesTextLabel">setUsesTextLabel</a>() is used to set whether tool buttons +should display a textual label in addition to pixmaps +(see <a href="tqtoolbutton.html">TQToolButton</a> for more information). +</ul> +<p> The user can drag dock windows into any enabled docking area. Dock +windows can also be dragged <em>within</em> a docking area, for example +to rearrange the order of some toolbars. Dock windows can also be +dragged outside any docking area (undocked or 'floated'). Being +able to drag dock windows can be enabled (the default) and +disabled using <a href="#setDockWindowsMovable">setDockWindowsMovable</a>(). +<p> The <a href="ntqt.html#Dock-enum">Minimized</a> edge is a hidden dock area. If this dock area is +enabled the user can hide (minimize) a dock window or show (restore) +a minimized dock window by clicking the dock window handle. If the +user hovers the mouse cursor over one of the handles, the caption of +the dock window is displayed in a tool tip (see +<a href="tqwidget.html#caption">TQDockWindow::caption</a>() or <a href="tqtoolbar.html#label">TQToolBar::label</a>()), so if you enable the +<a href="ntqt.html#Dock-enum">Minimized</a> dock area, it is best to specify a meaningful caption +or label for each dock window. To minimize a dock window +programmatically use <a href="#moveDockWindow">moveDockWindow</a>() with an edge of <a href="ntqt.html#Dock-enum">Minimized</a>. +<p> Dock windows are moved transparently by default, i.e. during the +drag an outline rectangle is drawn on the screen representing the +position of the dock window as it moves. If you want the dock +window to be shown normally whilst it is moved use +<a href="#setOpaqueMoving">setOpaqueMoving</a>(). +<p> The location of a dock window, i.e. its dock area and position +within the dock area, can be determined by calling <a href="#getLocation">getLocation</a>(). +Movable dock windows can be lined up to minimize wasted space with +<a href="#lineUpDockWindows">lineUpDockWindows</a>(). Pointers to the dock areas are available from +<a href="#topDock">topDock</a>(), <a href="#leftDock">leftDock</a>(), <a href="#rightDock">rightDock</a>() and <a href="#bottomDock">bottomDock</a>(). A customize +menu item is added to the pop up dock window menu if +<a href="#isCustomizable">isCustomizable</a>() returns TRUE; it returns FALSE by default. +Reimplement isCustomizable() and <a href="#customize">customize</a>() if you want to offer +this extra menu item, for example, to allow the user to change +settings relating to the main window and its toolbars and dock +windows. +<p> The main window's menu bar is fixed (at the top) by default. If +you want a movable menu bar, create a <a href="tqmenubar.html">TQMenuBar</a> as a stretchable +widget inside its own movable dock window and restrict this dock +window to only live within the <a href="ntqt.html#Dock-enum">Top</a> or <a href="ntqt.html#Dock-enum">Bottom</a> dock: +<p> <pre> + <a href="tqtoolbar.html">TQToolBar</a> *tb = new <a href="tqtoolbar.html">TQToolBar</a>( this ); + <a href="#addDockWindow">addDockWindow</a>( tb, tr( "Menubar" ), Top, FALSE ); + <a href="tqmenubar.html">TQMenuBar</a> *mb = new <a href="tqmenubar.html">TQMenuBar</a>( tb ); + mb-><a href="ntqframe.html#setFrameStyle">setFrameStyle</a>( TQFrame::NoFrame ); + tb-><a href="tqtoolbar.html#setStretchableWidget">setStretchableWidget</a>( mb ); + <a href="#setDockEnabled">setDockEnabled</a>( tb, Left, FALSE ); + <a href="#setDockEnabled">setDockEnabled</a>( tb, Right, FALSE ); + </pre> + +<p> An application with multiple dock windows can choose to save the +current dock window layout in order to restore it later, e.g. in +the next session.
