Method

GtkWidgetset_child_visible

Declaration [src]

void
gtk_widget_set_child_visible (
  GtkWidget* widget,
  gboolean child_visible
)

Description [src]

Sets whether widget should be mapped along with its parent.

The child visibility can be set for widget before it is added to a container with gtk_widget_set_parent(), to avoid mapping children unnecessary before immediately unmapping them. However it will be reset to its default state of TRUE when the widget is removed from a container.

Note that changing the child visibility of a widget does not queue a resize on the widget. Most of the time, the size of a widget is computed from all visible children, whether or not they are mapped. If this is not the case, the container can queue a resize itself.

This function is only useful for container implementations and should never be called by an application.

Parameters

child_visible gboolean
 

If TRUE, widget should be mapped along with its parent.
