apply

public void apply(org.eclipse.swt.graphics.GC gc)

Description copied from class: SvgGraphic

Apply this svg graphic to the given graphics context.

Note that to support the rather abstract structure of svg, each time this method is called all transformations and css properties to be calculated and applied. If this is a shape, it will be painted to the graphics context. Containers will recursively make this call on their children.

Specified by:

apply in class SvgGraphic

Parameters:

gc - the gc to use in all graphics operations

public SvgElement[] getElements()

an array of child elements contained by this element.

isEmpty

Returns:
