Method

GtkWidgetset_has_window

Declaration [src]

void
gtk_widget_set_has_window (
  GtkWidget* widget,
  gboolean has_window
)

Description [src]

Specifies whether widget has a GdkWindow of its own. Note that all realized widgets have a non-NULL “window” pointer (gtk_widget_get_window() never returns a NULL window when a widget is realized), but for many of them it’s actually the GdkWindow of one of its parent widgets. Widgets that do not create a %window for themselves in GtkWidget::realize must announce this by calling this function with has_window = FALSE.

This function should only be called by widget implementations, and they should call it in their init() function.

Available since:2.18

Parameters

has_window gboolean
 

Whether or not widget has a window.
