\obsolete |
|
835 |
\brief The QWorkspace widget provides a workspace window that can be |
|
836 |
used in an MDI application. |
|
837 |
||
838 |
This class is deprecated. Use QMdiArea instead. |
|
839 |
||
840 |
Multiple Document Interface (MDI) applications are typically |
|
841 |
composed of a main window containing a menu bar, a toolbar, and |
|
842 |
a central QWorkspace widget. The workspace itself is used to display |
|
843 |
a number of child windows, each of which is a widget. |
|
844 |
||
845 |
The workspace itself is an ordinary Qt widget. It has a standard |
|
846 |
constructor that takes a parent widget. |
|
847 |
Workspaces can be placed in any layout, but are typically given |
|
848 |
as the central widget in a QMainWindow: |
|
849 |
||
850 |
\snippet doc/src/snippets/code/src_gui_widgets_qworkspace.cpp 0 |
|
851 |
||
852 |
Child windows (MDI windows) are standard Qt widgets that are |
|
853 |
inserted into the workspace with addWindow(). As with top-level |
|
854 |
widgets, you can call functions such as show(), hide(), |
|
855 |
showMaximized(), and setWindowTitle() on a child window to change |
|
856 |
its appearance within the workspace. You can also provide widget |
|
857 |
flags to determine the layout of the decoration or the behavior of |
|
858 |
the widget itself. |
|
859 |
||
860 |
To change or retrieve the geometry of a child window, you must |
|
861 |
operate on its parentWidget(). The parentWidget() provides |
|
862 |
access to the decorated frame that contains the child window |
|
863 |
widget. When a child window is maximised, its decorated frame |
|
864 |
is hidden. If the top-level widget contains a menu bar, it will display |
|
865 |
the maximised window's operations menu to the left of the menu |
|
866 |
entries, and the window's controls to the right. |
|
867 |
||
868 |
A child window becomes active when it gets the keyboard focus, |
|
869 |
or when setFocus() is called. The user can activate a window by moving |
|
870 |
focus in the usual ways, for example by clicking a window or by pressing |
|
871 |
Tab. The workspace emits a signal windowActivated() when the active |
|
872 |
window changes, and the function activeWindow() returns a pointer to the |
|
873 |
active child window, or 0 if no window is active. |
|
874 |
||
875 |
The convenience function windowList() returns a list of all child |
|
876 |
windows. This information could be used in a popup menu |
|
877 |
containing a list of windows, for example. This feature is also |
|
878 |
available as part of the \l{Window Menu} Solution.
|
|
879 |
||
880 |
QWorkspace provides two built-in layout strategies for child |
|
881 |
windows: cascade() and tile(). Both are slots so you can easily |
|
882 |
connect menu entries to them. |
|
883 |
||
884 |
\table |
|
885 |
\row \o \inlineimage mdi-cascade.png |
|
886 |
\o \inlineimage mdi-tile.png |
|
887 |
\endtable |
|
888 |
||
889 |
If you want your users to be able to work with child windows |
|
890 |
larger than the visible workspace area, set the scrollBarsEnabled |
|
891 |
property to true. |

\property QWorkspace::scrollBarsEnabled |

\brief whether the workspace provides scroll bars |

3182 |
If this property is true, the workspace will provide scroll bars if any |
|
3183 |
of the child windows extend beyond the edges of the visible |
|
3184 |
workspace. The workspace area will automatically increase to |
|
3185 |
contain child windows if they are resized beyond the right or |
|
3186 |
bottom edges of the visible area. |
|
3187 |
||
3188 |
If this property is false (the default), resizing child windows |
|
3189 |
out of the visible area of the workspace is not permitted, although |
|
3190 |
it is still possible to position them partially outside the visible area. |
