Description
GooCanvasGroupModel represents a group of items. Groups can be nested to any depth, to create a hierarchy of items. Items are ordered within each group, with later items being displayed above earlier items.
GooCanvasGroupModel is a subclass of GooCanvasItemModelSimple and so inherits all of the style properties such as "stroke-color", "fill-color" and "line-width". Setting a style property on a GooCanvasGroupModel will affect all children of the GooCanvasGroupModel (unless the children override the property setting).
GooCanvasGroupModel implements the GooCanvasItemModel interface, so you
can use the GooCanvasItemModel functions such as
goo_canvas_item_model_raise()
and goo_canvas_item_model_rotate()
, and the
properties such as "visibility" and "pointer-events".
To create a GooCanvasGroupModel use goo_canvas_group_model_new()
.
To get or set the properties of an existing GooCanvasGroupModel, use
g_object_get()
and g_object_set()
.
To respond to events such as mouse clicks on the group you must connect
to the signal handlers of the corresponding GooCanvasGroup objects.
(See goo_canvas_get_item()
and "item-created".)
