173 \class QSizeGrip -
174 -
175 \brief The QSizeGrip class provides a resize handle for resizing top-level windows. -
176 -
177 \ingroup mainwindow-classes -
178 \ingroup basicwidgets -
179 \inmodule QtWidgets -
180 -
181 This widget works like the standard Windows resize handle. In the -
182 X11 version this resize handle generally works differently from -
183 the one provided by the system if the X11 window manager does not -
184 support necessary modern post-ICCCM specifications. -
185 -
186 Put this widget anywhere in a widget tree and the user can use it -
187 to resize the top-level window or any widget with the Qt::SubWindow -
188 flag set. Generally, this should be in the lower right-hand corner. -
189 Note that QStatusBar already uses this widget, so if you have a -
190 status bar (e.g., you are using QMainWindow), then you don't need -
191 to use this widget explicitly. -
192 -
193 On some platforms the size grip automatically hides itself when the -
194 window is shown full screen or maximised. -
195 -

198 \li A size grip widget at the bottom-right corner of a main window, shown in the -
199 \l{Fusion Style Widget Gallery}{Fusion widget style}. -
200 \endtable -
201 -
202 The QSizeGrip class inherits QWidget and reimplements the \l -
203 {QWidget::mousePressEvent()}{mousePressEvent()} and \l -
204 {QWidget::mouseMoveEvent()}{mouseMoveEvent()} functions to feature -
205 the resize functionality, and the \l -
206 {QWidget::paintEvent()}{paintEvent()} function to render the -
207 size grip widget. -
