Get a widget's extent
PhRect_t *PtWidgetExtent( PtWidget_t *widget,
PhRect_t *extent );
ph
This macro sets the specified
PhRect_t
structure to the extent of the
specified widget and returns a pointer to that structure.
The same pointer as extent, or NULL if no
PhRect_t structure is provided or if the widget
pointer is invalid.
|
A widget's extent isn't calculated until the widget is
either realized or forced to calculate the extent by a call to
PtExtentWidget().
If the widget hasn't been realized, be sure to call
PtExtentWidget() first. |
PhRect_t extent;
PtWidget_t *labelwidget;
PtRealizeWidget( labelwidget );
PtWidgetExtent( labelwidget, &extent);
