|

|
|

|
|

|
|
The TQWorkspace 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 TQWorkspace. The workspace itself contains zero, one or more
|
||
|
|
document windows, each of which is a widget.
|
||
|
|
<p> The workspace itself is an ordinary TQt widget. It has a standard
|
||
|
|
constructor that takes a parent widget and an object name. The
|
||
|
4 months ago
|
parent window is usually a <a href="tqmainwindow.html">TQMainWindow</a>, but it need not be.
|
||
|
13 years ago
|
<p> Document windows (i.e. MDI windows) are also ordinary TQt widgets
|
||
|
|
which have the workspace as their parent widget. When you call
|
||
|

|
<a href="tqwidget.html#show">show</a>(), <a href="tqwidget.html#hide">hide</a>(), <a href="tqwidget.html#showMaximized">showMaximized</a>(), <a href="tqwidget.html#setCaption">setCaption</a>(), etc. on a document
|
||
|
13 years ago
|
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
|
||
|
5 months ago
|
on the MDI widget's <a href="tqwidget.html#parentWidget">parentWidget</a>(). (The parentWidget() provides
|
||
|
13 years ago
|
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>.
|
||
|
5 months ago
|
You can also activate a window in code using <a href="tqwidget.html#setFocus">setFocus</a>(). The user
|
||
|
13 years ago
|
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> TQWorkspace 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, TQWorkspace 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

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.
