Class
GtkSnapshot
Description [src]
final class Gtk.Snapshot : Gdk.Snapshot {
/* No available fields */
}GtkSnapshot assists in creating GskRenderNodes for widgets.
It functions in a similar way to a cairo context, and maintains a stack of render nodes and their associated transformations.
The node at the top of the stack is the the one that gtk_snapshot_append_… functions operate on. Use the gtk_snapshot_push_… functions and gtk_snapshot_pop() to change the current node.
The typical way to obtain a GtkSnapshot object is as an argument to
the Gtk.WidgetClass.snapshot vfunc. If you need to create your own
GtkSnapshot, use gtk_snapshot_new().
