Constructor Detail

RadioRenderer

public RadioRenderer(Radio modelElement)

Creates a new RadioRenderer instance.

Parameters:

modelElement - the model element

Method Detail

getNextRenderer

public IRenderer getNextRenderer()

Gets a new instance of this class to be used as a next renderer, after this renderer is used, if IRenderer.layout(LayoutContext) is called more than once.

Returns:

new renderer instance

drawBorder

public void drawBorder(DrawContext drawContext)

Performs the drawing operation for the border of this renderer, if defined by the Property.BORDER_TOP, Property.BORDER_RIGHT, Property.BORDER_BOTTOM and Property.BORDER_LEFT values in either the layout element or this IRenderer itself.

Overrides:

drawBorder in class AbstractRenderer

Parameters:

drawContext - the context (canvas, document, etc.) of this drawing operation

drawBackground

public void drawBackground(DrawContext drawContext)

Draws a background layer if it is defined by a key Property.BACKGROUND in either the layout element or this IRenderer itself.

Overrides:

drawBackground in class AbstractRenderer

Parameters:

drawContext - the context (canvas, document, etc) of this drawing operation.
