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

200 \l{Fusion Style Widget Gallery}{Fusion widget style}.-
201 \endtable-
202-
203 The QSizeGrip class inherits QWidget and reimplements the \l-
204 {QWidget::mousePressEvent()}{mousePressEvent()} and \l-
205 {QWidget::mouseMoveEvent()}{mouseMoveEvent()} functions to feature-
206 the resize functionality, and the \l-
207 {QWidget::paintEvent()}{paintEvent()} function to render the-
208 size grip widget.-
