QMdiSubWindow has its own layout, which consists of the - title bar and a center area for the internal widget. - - \image qmdisubwindowlayout.png - - The most common way to construct a QMdiSubWindow is to call - QMdiArea::addSubWindow() with the internal widget as the argument. - You can also create a subwindow yourself, and set an internal - widget by calling setWidget(). - - You use the same API when programming with subwindows as with - regular top-level windows (e.g., you can call functions such as - show(), hide(), showMaximized(), and setWindowTitle()). - - \section1 Subwindow Handling - - QMdiSubWindow also supports behavior specific to subwindows in - an MDI area. - - By default, each QMdiSubWindow is visible inside the MDI area - viewport when moved around, but it is also possible to specify - transparent window movement and resizing behavior, where only - the outline of a subwindow is updated during these operations. - The setOption() function is used to enable this behavior. - - The isShaded() function detects whether the subwindow is - currently shaded (i.e., the window is collapsed so that only the - title bar is visible). To enter shaded mode, call showShaded(). - QMdiSubWindow emits the windowStateChanged() signal whenever the - window state has changed (e.g., when the window becomes minimized, - or is restored). It also emits aboutToActivate() before it is - activated. - - In keyboard-interactive mode, the windows are moved and resized - with the keyboard. You can enter this mode through the system menu - of the window. The keyboardSingleStep and keyboardPageStep - properties control the distance the widget is moved or resized for - each keypress event. When shift is pressed down page step is used; - otherwise single step is used. - - You can also change the active window with the keyboard. By - pressing the control and tab keys at the same time, the next - (using the current \l{QMdiArea::}{WindowOrder}) subwindow will be - activated. By pressing control, shift, and tab, you will activate - the previous window. This is equivalent to calling - \l{QMdiArea::}{activateNextSubWindow()} and - \l{QMdiArea::}{activatePreviousSubWindow()}. Note that these - shortcuts overrides global shortcuts, but not the \l{QMdiArea}s - shortcuts. - - \sa QMdiArea -*/ - -/*! - \enum QMdiSubWindow::SubWindowOption - - This enum describes options that customize the behavior - of QMdiSubWindow. - - \omitvalue AllowOutsideAreaHorizontally - \omitvalue AllowOutsideAreaVertically - - \value RubberBandResize If you enable this option, a rubber band - control is used to represent the subwindow's outline, and the user - resizes this instead of the subwindow itself. - As a result, the subwindow maintains its original position and size - until the resize operation has been completed, at which time it will - receive a single QResizeEvent. - By default, this option is disabled. - - \value RubberBandMove If you enable this option, a rubber band - control is used to represent the subwindow's outline, and the user - moves this instead of the subwindow itself. - As a result, the subwindow remains in its original position until - the move operation has completed, at which time a QMoveEvent is - sent to the window. By default, this option is disabled. -*/ - -/*! - \fn QMdiSubWindow::windowStateChanged(Qt::WindowStates oldState, Qt::WindowStates newState) - - QMdiSubWindow emits this signal after the window state changes. \a - oldState is the window state before it changed, and \a newState is the - new, current state. -*/ - -/*! - \fn QMdiSubWindow::aboutToActivate() - - QMdiSubWindow emits this signal immediately before it is - activated.
