Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.

public Canvas getCanvas()
CanvasItem
If a canvas
hasn't been specified via setCanvas()
, the canvas for this item will be auto-created
as configured by the methods setAutoChildProperties()
and setAutoChildConstructor()
.
Note that subclasses of CanvasItem
may use a different AutoChild name than
just "canvas". For example, SliderItem
uses "slider", and in that case,
you need to use the specific APIs provided by the subclass.
Note that Canvas.canvasItem
will be set on the canvas to point back to this
item.
This component is an AutoChild named "canvas". For an overview of how to use and
configure AutoChildren, see Using AutoChildren
