+The building blocks of a &kommander; dialog are the widgets.  They are like any other widget in the &Qt; and &kde; libraries except they have some extra functionality that allows them to have a <quote>text association</quote>.  Text is associated with a state of the widget or its populate slot.  The number of states depends on the widget.  If a widget only has one state, that state is called default.
+</para>
+
+<note>
+<para>The main dialog has two special states for &kommander; text.  They are Initialization and Destroy.  These are run when the dialog is initialized and when it is destroyed.  These protect against what is know as <quote>race</quote> problems on open and mean that you do not require any special procedures on close to manage housekeeping.</para>
+<para>In case of using a MainWindow based application (created with &Qt; Designer), there are no Initialization and Destroy states, instead the <emphasis>initialize</emphasis> and <emphasis>destroy</emphasis> signals can be used to get information when is the application constructed or closed</para>
+</note>
+
+<para>
+Below are the standard &kommander; widgets. Each of them has numerous functions, you can learn about them by looking at the widget functions in the <guilabel>Function Browser</guilabel>. Many of them have signals and slots as well, documentation about these methods can be found in the &Qt; and &kde; API documentation. Each &kommander; widget has a note about its base widget.

+<para>
+A simple widget that contains an image or text label.  The pixmap to display is set in the pixmap property.  The text is set in the text property.  Only one of these properties can be set at the same time (I think, I can't get the editor to set both at the same time).  If scaledContents is set to true the image will be scaled to fit the size of the widget.  The format of the text can be set with the textFormat property.

+A container to organize buttons into a group.  An optional title can be set using the title property.  The frame can be adjusted with the lineWidth property.

Radio buttons can be set to non-exclusive using the radioButtonExclusive property.  (I am not so sure that this property actually works.)

It is possible to connect the menu entries to the popupmenu's own <emphasis>execute</emphasis> function, in which case the text assigned to the <emphasis>default</emphasis> state is run. When adding menu items you can assign an index to them and handle the all the items on a menu in the menu widget as the request passes this index back. To see how this works look at the current example <link linkend="example-key-value">keyvaluecombo.kmdr</link> included with this release. To find it look on the tools menu of the editor for the examples dialog.
