Detailed Description
The QWorkspace widget provides a workspace window that can contain decorated windows, e.g. for MDI.
An MDI application has one main window with a menu bar. The central
widget of this window is a workspace. The workspace itself contains
zero, one or more document windows, each of which displays a
document.
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 (alias MDI windows) are also ordinary Qt widgets,
that have the workspace as 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 the geometry of the MDI windows it is necessary to make
the necessary function calls to the parentWidget() of the widget, as
this will move or resize the decorated window.
A document window becomes active when it gets the keyboard focus.
You can activate it using setFocus(), and the user can activate it
by moving focus in the normal ways. 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 "&Windows" 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.
In case the toplevel window contains a menu bar and a document
window is maximized, QWorkspace moves the document window's
minimize, restore and close buttons from the document window's frame
to the workspace window's menu bar, and inserts a window operations
menu on the extreme left of the menu bar.
Warning: User interface research indicates that most users have
problems with MDI applications. Use this class cautiously.
