Method
GtkWidgetset_child_visible
Declaration [src]
void
gtk_widget_set_child_visible (
GtkWidget* widget,
gboolean child_visible
)
Description [src]
Sets whether the 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 widget implementations and should never be called by an application.
