Description
GooCanvasGroup 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.
GooCanvasGroup is a subclass of GooCanvasItemSimple and so inherits all of the style properties such as "stroke-color", "fill-color" and "line-width". Setting a style property on a GooCanvasGroup will affect all children of the GooCanvasGroup (unless the children override the property setting).
GooCanvasGroup implements the GooCanvasItem interface, so you can use
the GooCanvasItem functions such as goo_canvas_item_raise()
and
goo_canvas_item_rotate()
, and the properties such as "visibility" and
"pointer-events".
If the "width" and "height" properties are set to positive values then the group is clipped to the given size.
To create a GooCanvasGroup use goo_canvas_group_new()
.
To get or set the properties of an existing GooCanvasGroup, use
g_object_get()
and g_object_set()
.
