71The QWorkspace widget provides a workspace window that can
72contain decorated windows, e.g. for MDI.
73<p>
74<p>
75
76
77<p> MDI (multiple document interface) applications typically have one
78main window with a menu bar and toolbar, and a central widget that
79is a QWorkspace. The workspace itself contains zero, one or more
80document windows, each of which is a widget.
81<p> The workspace itself is an ordinary Qt widget. It has a standard
82constructor that takes a parent widget and an object name. The
83parent window is usually a <a href="qmainwindow.html">QMainWindow</a>, but it need not be.
84<p> Document windows (i.e. MDI windows) are also ordinary Qt widgets
85which have the workspace as their parent widget. When you call
86<a href="qwidget.html#show">show</a>(), <a href="qwidget.html#hide">hide</a>(), <a href="qwidget.html#showMaximized">showMaximized</a>(), <a href="qwidget.html#setCaption">setCaption</a>(), etc. on a document
87window, it is shown, hidden, etc. with a frame, caption, icon and
88icon text, just as you'd expect. You can provide widget flags
89which will be used for the layout of the decoration or the
90behaviour of the widget itself.
91<p> To change or retrieve the geometry of MDI windows you must operate
92on the MDI widget's <a href="qwidget.html#parentWidget">parentWidget</a>(). (The parentWidget() provides
93access to the decorated window in which the MDI window's widget is
94shown.)
95<p> A document window becomes active when it gets the <a href="focus.html#keyboard-focus">keyboard focus</a>.
96You can also activate a window in code using <a href="qwidget.html#setFocus">setFocus</a>(). The user
97can activate a window by moving focus in the usual ways, for
98example by clicking a window or by pressing Tab. The workspace
99emits a signal <a href="#windowActivated">windowActivated</a>() when it detects the activation
100change, and the function <a href="#activeWindow">activeWindow</a>() always returns a pointer
101to the active document window.
102<p> The convenience function <a href="#windowList">windowList</a>() returns a list of all
103document windows. This is useful to create a popup menu
104"<u>W</u>indows" on the fly, for example.
105<p> QWorkspace provides two built-in layout strategies for child
106windows: <a href="#cascade">cascade</a>() and <a href="#tile">tile</a>(). Both are slots so you can easily
107connect menu entries to them.
108<p> If you want your users to be able to work with document windows
109larger than the actual workspace, set the scrollBarsEnabled
110property to TRUE.
111<p> If the top-level window contains a menu bar and a document window
112is maximised, QWorkspace moves the document window's minimize,
113restore and close buttons from the document window's frame to the
114workspace window's menu bar. It then inserts a window operations
115menu at the far left of the menu bar.

201<p>
202<hr><h2>Property Documentation</h2>
203<h3 class=fn>bool <a name="scrollBarsEnabled-prop"></a>scrollBarsEnabled</h3>
204<p>This property holds whether the workspace provides scrollbars.
205<p>If this property is set to TRUE, it is possible to resize child
206windows over the right or the bottom edge out of the visible area
207of the workspace. The workspace shows scrollbars to make it
208possible for the user to access those windows. If this property is
209set to FALSE (the default), resizing windows out of the visible
210area of the workspace is not permitted.
211
212<p>Set this property's value with <a href="#setScrollBarsEnabled">setScrollBarsEnabled</a>() and get this property's value with <a href="#scrollBarsEnabled">scrollBarsEnabled</a>().
