Method

GtkWidgetregion_intersect

Declaration [src]

cairo_region_t*
gtk_widget_region_intersect (
  GtkWidget* widget,
  const cairo_region_t* region
)

Description [src]

Computes the intersection of a widget’s area and region, returning the intersection. The result may be empty, use cairo_region_is_empty() to check.

Deprecated since:	3.14
Use `gtk_widget_get_allocation()` and `cairo_region_intersect_rectangle()` to get the same behavior.

Parameters

`region`	`cairo_region_t`
	A #cairo_region_t, in the same coordinate system as `widget`->allocation. That is, relative to `widget`->window for widgets which return `FALSE` from gtk_widget_get_has_window(); relative to the parent window of `widget`->window otherwise.
	The data is owned by the caller of the function.

Return value

Returns:	`cairo_region_t`
	A newly allocated region holding the intersection of `widget` and `region`.
	The caller of the method takes ownership of the data, and is responsible for freeing it.
