- \class QWorkspace
- \obsolete
- \brief The QWorkspace widget provides a workspace window that can be
- used in an MDI application.
-
- This class is deprecated. Use QMdiArea instead.
-
- Multiple Document Interface (MDI) applications are typically
- composed of a main window containing a menu bar, a toolbar, and
- a central QWorkspace widget. The workspace itself is used to display
- a number of child windows, each of which is a widget.
-
- The workspace itself is an ordinary Qt widget. It has a standard
- constructor that takes a parent widget.
- Workspaces can be placed in any layout, but are typically given
- as the central widget in a QMainWindow:
-
- \snippet doc/src/snippets/code/src_gui_widgets_qworkspace.cpp 0
-
- Child windows (MDI windows) are standard Qt widgets that are
- inserted into the workspace with addWindow(). As with top-level
- widgets, you can call functions such as show(), hide(),
- showMaximized(), and setWindowTitle() on a child window to change
- its appearance within the workspace. You can also provide widget
- flags to determine the layout of the decoration or the behavior of
- the widget itself.
-
- To change or retrieve the geometry of a child window, you must
- operate on its parentWidget(). The parentWidget() provides
- access to the decorated frame that contains the child window
- widget. When a child window is maximised, its decorated frame
- is hidden. If the top-level widget contains a menu bar, it will display
- the maximised window's operations menu to the left of the menu
- entries, and the window's controls to the right.
-
- A child window becomes active when it gets the keyboard focus,
- or when setFocus() is called. The user can activate a window by moving
- focus in the usual ways, for example by clicking a window or by pressing
- Tab. The workspace emits a signal windowActivated() when the active
- window changes, and the function activeWindow() returns a pointer to the
- active child window, or 0 if no window is active.
-
- The convenience function windowList() returns a list of all child
- windows. This information could be used in a popup menu
- containing a list of windows, for example. This feature is also
- available as part of the \l{Window Menu} Solution.
-
- QWorkspace provides two built-in layout strategies for child
- windows: cascade() and tile(). Both are slots so you can easily
- connect menu entries to them.
-
- \table
- \row \o \inlineimage mdi-cascade.png
- \o \inlineimage mdi-tile.png
- \endtable
-
- If you want your users to be able to work with child windows
- larger than the visible workspace area, set the scrollBarsEnabled
- property to true.
