Method

Gtk.Widget.snapshot_child

Declaration [src]

void
gtk_widget_snapshot_child (
  GtkWidget* widget,
  GtkWidget* child,
  GtkSnapshot* snapshot
)

Description [src]

Snapshot the a child of widget.

When a widget receives a call to the snapshot function, it must send synthetic GtkWidgetClass.snapshot() calls to all children. This function provides a convenient way of doing this. A widget, when it receives a call to its GtkWidgetClass.snapshot() function, calls gtk_widget_snapshot_child() once for each child, passing in the snapshot the widget received.

gtk_widget_snapshot_child() takes care of translating the origin of snapshot, and deciding whether the child needs to be snapshot.

This function does nothing for children that implement GtkNative.

Parameters

child GtkWidget
 

a child of widget

 The data is owned by the caller of the function
