Parameters

region Region

a #cairo_region_t, in the same coordinate system as @widget->allocation. That is, relative to @widget->window for %NO_WINDOW widgets; relative to the parent window of @widget->window for widgets with their own window.

Return: A newly allocated region holding the intersection of @widget and @region. The coordinates of the return value are relative to @widget->window for %NO_WINDOW widgets, and relative to the parent window of @widget->window for widgets with their own window.

Detailed Description

Deprecated: Use gtk_widget_get_allocation() and cairo_region_intersect_rectangle() to get the same behavior.
