CanvasStyle

Description:

public class CanvasStyle : Object

CanvasStyle provides support for cascading style properties for canvas items.

It is intended to be used when implementing new canvas items.

<note><para> The cascading styles canvas feature may be removed in a future version of GooCanvas. </para></note >

Style properties are identified by a unique Quark, and contain arbitrary data stored in a Value.

CanvasStyle also provides a few convenience functions such as set_stroke_options and set_fill_options which efficiently apply an item's standard style properties to the given cairo_t.
