Detailed Description

The QMdiSubWindow class provides a subwindow class for QMdiArea.

Since: 4.3

\inmodule QtWidgets

QMdiSubWindow represents a top-level window in a QMdiArea, and consists of a title bar with window decorations, an internal widget, and (depending on the current style) a window frame and a size grip. QMdiSubWindow has its own layout, which consists of the title bar and a center area for the internal widget.

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()).

Member Enumeration Documentation

◆ SubWindowOption

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.

Constructor & Destructor Documentation

◆ QMdiSubWindow()

QMdiSubWindow::QMdiSubWindow	(	QWidget *	parent = `nullptr`,
		Qt::WindowFlags	flags = `Qt::WindowFlags()`
	)

Constructs a new QMdiSubWindow widget. The parent and flags arguments are passed to QWidget's constructor.

Instead of using addSubWindow(), it is also simply possible to use setParent() when you add the subwindow to a QMdiArea.

Note that only \l{QMdiSubWindow}s can be set as children of QMdiArea; you cannot, for instance, write:

//bad code
QMdiArea mdiArea;
QTextEdit editor(&mdiArea); // invalid child widget

See also: QMdiArea::addSubWindow()

Definition at line 2244 of file qmdisubwindow.cpp.

◆ ~QMdiSubWindow()

QMdiSubWindow::~QMdiSubWindow ( )

Destroys the subwindow.

See also: QMdiArea::removeSubWindow()

Definition at line 2279 of file qmdisubwindow.cpp.

Member Function Documentation

◆ aboutToActivate

QMdiSubWindow::aboutToActivate ( )

signal

QMdiSubWindow emits this signal immediately before it is activated. After the subwindow has been activated, the QMdiArea that manages the subwindow will also emit the \l{QMdiArea::}{subWindowActivated()} signal.

◆ showShaded

void QMdiSubWindow::showShaded ( )

slot

Calling this function makes the subwindow enter the shaded mode. When the subwindow is shaded, only the title bar is visible.

Although shading is not supported by all styles, this function will still show the subwindow as shaded, regardless of whether support for shading is available. However, when used with styles without shading support, the user will be unable to return from shaded mode through the user interface (e.g., through a shade button in the title bar).

Property Documentation

◆ keyboardPageStep

QMdiSubWindow::keyboardPageStep

readwrite

sets how far a widget should move or resize when using the keyboard page keys.

When in keyboard-interactive mode, you can use the arrow and page keys to either move or resize the window. This property controls the page keys. The common way to enter keyboard interactive mode is to enter the subwindow menu, and select either "resize" or "move".

The default keyboard page step value is 20 pixels.

◆ keyboardSingleStep

QMdiSubWindow::keyboardSingleStep

readwrite

sets how far a widget should move or resize when using the keyboard arrow keys.

When in keyboard-interactive mode, you can use the arrow and page keys to either move or resize the window. This property controls the arrow keys. The common way to enter keyboard interactive mode is to enter the subwindow menu, and select either "resize" or "move".

The default keyboard single step value is 5 pixels.
