example demonstrates the use of Qt's widget flags to provide + toplevel widgets with customized window decorations. + + It provides a graphical user interface for selecting different + options for widget decoration and behavior, and passes the + appropriate widget flags to the QWidget constructor. + QWidget::reparent() is used to change the widget flags at runtime. + + \warning Note that the interpretation and functionality of the + widget flags depends on the window manager used when running the + application.

This is the standard behavior for + dialog boxes, especially if they are modeless, and for other + secondary toplevel widgets. + + To provide a taskbar entry the widget must have no parent, + in which case we need to use the \c WGroupLeader flag to + prevent blocking through the modal main dialog. Applications + that can have multiple toplevel windows open simultaneously + should use this combination. + + \printto cbBehaviorPopup + A toplevel widget can stay on top of the whole desktop if the + window manager supports this functionality. + \footnote Unfortunately some X11 window managers also retquire the \c + WX11BypassWM flag to be set in addition; but some other X11 window + managers will have problems if this flag is set. \endfootnote + + Widgets that display important or realtime information (i.e. IRC + clients) might benefit from using that flag. + + \printto cbBehaviorModal + A popup widget is a short lived modal widget that closes + automatically. Popup menus are a typical example for such widgets. + + \printto cbBehaviorTool + A modal widget blocks input to other toplevel widgets, unless + those are in a different modal group (see \c WGroupLeader). + Dialogs are often modal, and the QDialog class provides an easy API + to create and display them without the need to explicitly use this + flag. + + \printto !widget + A tool window will never have a task bar entry (even if it + has no parent widget), and often has a smaller window + decoration. Tool windows are frequently used instead of + modeless dialogs. + + \printto else + The widget is created if it has not been created yet, or if it was + closed (since we use the \c WDestructiveClose flag). Note that the + window is not visible yet. + \footnote The example uses QGuardedPtr to make sure that the + pointer is reset to zero when the widget object is destroyed + due to the \c WDestructiveClose flag. \endfootnote + + \printto setCaption + If the widget has already been created the reparent() function is + used to modify the widget's flags.
