\class QSizeGrip
|
|
||||||
|
|
||||||
\brief The QSizeGrip class provides a resize handle for resizing top-level windows.
|
|
||||||
|
|
||||||
\ingroup mainwindow-classes
|
|
||||||
\ingroup basicwidgets
|
|
||||||
\inmodule QtWidgets
|
|
||||||
|
|
||||||
This widget works like the standard Windows resize handle. In the
|
|
||||||
X11 version this resize handle generally works differently from
|
|
||||||
the one provided by the system if the X11 window manager does not
|
|
||||||
support necessary modern post-ICCCM specifications.
|
|
||||||
|
|
||||||
Put this widget anywhere in a widget tree and the user can use it
|
|
||||||
to resize the top-level window or any widget with the Qt::SubWindow
|
|
||||||
flag set. Generally, this should be in the lower right-hand corner.
|
|
||||||
|
|
||||||
Note that QStatusBar already uses this widget, so if you have a
|
|
||||||
status bar (e.g., you are using QMainWindow), then you don't need
|
|
||||||
to use this widget explicitly. The same goes for QDialog, for which
|
|
||||||
you can just call \l {QDialog::setSizeGripEnabled()}
|
|
||||||
{QDialog::setSizeGripEnabled()}.
|
|
||||||
|
|
||||||
On some platforms the size grip automatically hides itself when the
|
|
||||||
window is shown full screen or maximised.
|
|
||||||

||||||

|

The QSizeGrip class inherits QWidget and reimplements the \l
|
|
||||||
{QWidget::mousePressEvent()}{mousePressEvent()} and \l
|
|
||||||
{QWidget::mouseMoveEvent()}{mouseMoveEvent()} functions to feature
|
|
||||||
the resize functionality, and the \l
|
|
||||||
{QWidget::paintEvent()}{paintEvent()} function to render the
|
|
||||||
size grip widget.
