|
---|
839 | \brief The QWorkspace widget provides a workspace window that can be
|
---|
840 | used in an MDI application.
|
---|
841 | \ingroup application
|
---|
842 |
|
---|
843 | This class is deprecated. Use QMdiArea instead.
|
---|
844 |
|
---|
845 | Multiple Document Interface (MDI) applications are typically
|
---|
846 | composed of a main window containing a menu bar, a toolbar, and
|
---|
847 | a central QWorkspace widget. The workspace itself is used to display
|
---|
848 | a number of child windows, each of which is a widget.
|
---|
849 |
|
---|
850 | The workspace itself is an ordinary Qt widget. It has a standard
|
---|
851 | constructor that takes a parent widget.
|
---|
852 | Workspaces can be placed in any layout, but are typically given
|
---|
853 | as the central widget in a QMainWindow:
|
---|
854 |
|
---|
855 | \snippet doc/src/snippets/code/src_gui_widgets_qworkspace.cpp 0
|
---|
856 |
|
---|
857 | Child windows (MDI windows) are standard Qt widgets that are
|
---|
858 | inserted into the workspace with addWindow(). As with top-level
|
---|
859 | widgets, you can call functions such as show(), hide(),
|
---|
860 | showMaximized(), and setWindowTitle() on a child window to change
|
---|
861 | its appearance within the workspace. You can also provide widget
|
---|
862 | flags to determine the layout of the decoration or the behavior of
|
---|
863 | the widget itself.
|
---|
864 |
|
---|
865 | To change or retrieve the geometry of a child window, you must
|
---|
866 | operate on its parentWidget(). The parentWidget() provides
|
---|
867 | access to the decorated frame that contains the child window
|
---|
868 | widget. When a child window is maximised, its decorated frame
|
---|
869 | is hidden. If the top-level widget contains a menu bar, it will display
|
---|
870 | the maximised window's operations menu to the left of the menu
|
---|
871 | entries, and the window's controls to the right.
|
---|
872 |
|
---|
873 | A child window becomes active when it gets the keyboard focus,
|
---|
874 | or when setFocus() is called. The user can activate a window by moving
|
---|
875 | focus in the usual ways, for example by clicking a window or by pressing
|
---|
876 | Tab. The workspace emits a signal windowActivated() when the active
|
---|
877 | window changes, and the function activeWindow() returns a pointer to the
|
---|
878 | active child window, or 0 if no window is active.
|
---|
879 |
|
---|
880 | The convenience function windowList() returns a list of all child
|
---|
881 | windows. This information could be used in a popup menu
|
---|
882 | containing a list of windows, for example. This feature is also
|
---|
883 | available as part of the \l{Window Menu} Solution.
|
---|
884 |
|
---|
885 | QWorkspace provides two built-in layout strategies for child
|
---|
886 | windows: cascade() and tile(). Both are slots so you can easily
|
---|
887 | connect menu entries to them.
|
---|
888 |
|
---|

|
---|
890 | \row \o \inlineimage mdi-cascade.png
|
---|
891 | \o \inlineimage mdi-tile.png
|
---|
892 | \endtable
|
---|
893 |
|
---|
894 | If you want your users to be able to work with child windows
|
---|
895 | larger than the visible workspace area, set the scrollBarsEnabled
|
---|
896 | property to true.
