|
||
|
|
|
||
|
|
|
||
|
|
The QWorkspace widget provides a workspace window that can
|
||
|
|
contain decorated windows, e.g. for MDI.
|
||
|
|
<p>
|
||
|
|
<p>
|
||
|
|
|
||
|
|
|
||
|
|
<p> MDI (multiple document interface) applications typically have one
|
||
|
|
main window with a menu bar and toolbar, and a central widget that
|
||
|
|
is a QWorkspace. The workspace itself contains zero, one or more
|
||
|
|
document windows, each of which is a widget.
|
||
|
|
<p> The workspace itself is an ordinary Qt widget. It has a standard
|
||
|
|
constructor that takes a parent widget and an object name. The
|
||
|
|
parent window is usually a <a href="qmainwindow.html">QMainWindow</a>, but it need not be.
|
||
|
|
<p> Document windows (i.e. MDI windows) are also ordinary Qt widgets
|
||
|
|
which have the workspace as their parent widget. When you call
|
||
|
|
<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
|
||
|
|
window, it is shown, hidden, etc. with a frame, caption, icon and
|
||
|
|
icon text, just as you'd expect. You can provide widget flags
|
||
|
|
which will be used for the layout of the decoration or the
|
||
|
|
behaviour of the widget itself.
|
||
|
|
<p> To change or retrieve the geometry of MDI windows you must operate
|
||
|
|
on the MDI widget's <a href="qwidget.html#parentWidget">parentWidget</a>(). (The parentWidget() provides
|
||
|
|
access to the decorated window in which the MDI window's widget is
|
||
|
|
shown.)
|
||
|
|
<p> A document window becomes active when it gets the <a href="focus.html#keyboard-focus">keyboard focus</a>.
|
||
|
|
You can also activate a window in code using <a href="qwidget.html#setFocus">setFocus</a>(). 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 <a href="#windowActivated">windowActivated</a>() when it detects the activation
|
||
|
|
change, and the function <a href="#activeWindow">activeWindow</a>() always returns a pointer
|
||
|
|
to the active document window.
|
||
|
|
<p> The convenience function <a href="#windowList">windowList</a>() returns a list of all
|
||
|
|
document windows. This is useful to create a popup menu
|
||
|
|
"<u>W</u>indows" on the fly, for example.
|
||
|
|
<p> QWorkspace provides two built-in layout strategies for child
|
||
|
|
windows: <a href="#cascade">cascade</a>() and <a href="#tile">tile</a>(). Both are slots so you can easily
|
||
|
|
connect menu entries to them.
|
||
|
|
<p> If you want your users to be able to work with document windows
|
||
|
|
larger than the actual workspace, set the scrollBarsEnabled
|
||
|
|
property to TRUE.
|
||
|
|
<p> If the top-level window contains a menu bar and a document window
|
||
|
|
is maximised, QWorkspace moves the document window's minimize,
|
||
|
|
restore and close buttons from the document window's frame to the
|
||
|
|
workspace window's menu bar. It then inserts a window operations
|
||
|
|
menu at the far left of the menu bar.

|

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