Make a widget and its children visible and possibly interactive
int PtRealizeWidget( PtWidget_t *widget );
This function makes a widget and its children visible to the user and possibly interactive. To create a hierarchy of widgets, you typically make successive calls to PtCreateWidget(), and then call PtRealizeWidget(), passing it the root of the hierarchy.
|Some widgets (for example, menus) have Pt_DELAY_REALIZE set in their Pt_ARG_FLAGS. Such delay-realized widgets aren't visibly rendered when their ancestors are realized. Although they're present in the hierarchy, delay-realized widgets become visible only when the application realizes them specifically with a call to PtRealizeWidget(). An application might do this, for example, if the user requested it to activate a menu.|
