Method
GtkWidgetcompute_point
Declaration [src]
gboolean
gtk_widget_compute_point (
  GtkWidget* widget,
  GtkWidget* target,
  const graphene_point_t* point,
  graphene_point_t* out_point
)
Description [src]
Translates the given point in widget‘s coordinates to coordinates
relative to target’s coordinate system.
In order to perform this operation, both widgets must share a common ancestor.
