DESCRIPTION
The QWorkspace widget provides a workspace window that can contain
decorated windows, e.g. for MDI.
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.
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 QMainWindow, but it need not be.
Document windows (i.e. MDI windows) are also ordinary Qt widgets which
have the workspace as their parent widget. When you call show(),
hide(), showMaximized(), setCaption(), 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.
To change or retrieve the geometry of MDI windows you must operate on
the MDI widget's parentWidget(). (The parentWidget() provides access to
the decorated window in which the MDI window's widget is shown.)
A document window becomes active when it gets the keyboard focus. You
can also activate a window in code using setFocus(). 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 it detects the activation change, and the
function activeWindow() always returns a pointer to the active document
window.
The convenience function windowList() returns a list of all document
windows. This is useful to create a popup menu" <u>W</u>indows" on the
fly, for example.
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.
If you want your users to be able to work with document windows larger
than the actual workspace, set the scrollBarsEnabled property to TRUE.
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.

Member Type Documentation
QWorkspace::WindowOrder
Specifies the order in which windows are returned from windowList().
QWorkspace::CreationOrder - The windows are returned in the order of
their creation
QWorkspace::StackingOrder - The windows are returned in the order of
their stacking
MEMBER FUNCTION DOCUMENTATIONQWorkspace::QWorkspace ( QWidget * parent = 0, const char * name = 0 )
Constructs a workspace with a parent and a name.
QWorkspace::~QWorkspace ()
Destroys the workspace and frees any allocated resources.
void QWorkspace::activateNextWindow () [slot]
Activates the next window in the child window chain.
See also activatePrevWindow().
void QWorkspace::activatePrevWindow () [slot]
Activates the previous window in the child window chain.
See also activateNextWindow().
QWidget * QWorkspace::activeWindow () const
Returns the active window, or 0 if no window is active.
Example: mdi/application.cpp.
void QWorkspace::cascade () [slot]
Arranges all the child windows in a cascade pattern.
See also tile().
Example: mdi/application.cpp.
void QWorkspace::closeActiveWindow () [slot]
Closes the child window that is currently active.
See also closeAllWindows().
void QWorkspace::closeAllWindows () [slot]
Closes all child windows.
The windows are closed in random order. The operation stops if a window
does not accept the close event.
See also closeActiveWindow().
bool QWorkspace::scrollBarsEnabled () const
Returns TRUE if the workspace provides scrollbars; otherwise returns
FALSE. See the "scrollBarsEnabled" property for details.
void QWorkspace::setScrollBarsEnabled ( bool enable )
Sets whether the workspace provides scrollbars to enable. See the
"scrollBarsEnabled" property for details.
void QWorkspace::tile () [slot]
Arranges all child windows in a tile pattern.
See also cascade().
Example: mdi/application.cpp.
void QWorkspace::windowActivated ( QWidget * w ) [signal]
This signal is emitted when the window widget w becomes active. Note
that w can be null, and that more than one signal may be emitted for a
single activation event.
See also activeWindow() and windowList().
QWidgetList QWorkspace::windowList ( WindowOrder order ) const
Returns a list of all windows. If order is CreationOrder (the default)
the windows are listed in the order in which they had been inserted
into the workspace. If order is StackingOrder the windows are listed in
their stacking order, with the topmost window being the last window in
the list.
QWidgetList is the same as QPtrList<QWidget>.
See also QPtrList.
Example: mdi/application.cpp.
QWidgetList QWorkspace::windowList () const
This function is obsolete. It is provided to keep old source working.
We strongly advise against using it in new code.
This is an overloaded member function, provided for convenience. It
behaves essentially like the above function.
Property Documentation
bool scrollBarsEnabled
This property holds whether the workspace provides scrollbars.
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.
Set this property's value with setScrollBarsEnabled() and get this
property's value with scrollBarsEnabled().
