Constructor Details

RadioRenderer

 public RadioRenderer 
             (Radio modelElement) 
            

Creates a new RadioRenderer instance.

Parameters:

modelElement - the model element

Method Details

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 any of the Property.BORDER 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.

applyBorderBox

 protected Rectangle applyBorderBox 
             (Rectangle rect, Border[] borders, boolean reverse) 
            

Applies the given border box (borders) on the given rectangle

Overrides:

applyBorderBox in class AbstractRenderer

Parameters:

rect - a rectangle paddings will be applied on.

borders - the borders to be applied on the given rectangle

reverse - indicates whether the border box will be applied inside (in case of false) or outside (in case of false) the rectangle.

Returns:

a border box of the renderer

createFlatRenderer

 protected IRenderer createFlatRenderer() 
            

Creates the flat renderer instance.

Specified by:

createFlatRenderer in class AbstractFormFieldRenderer

Returns:

the renderer instance

adjustFieldLayout

 protected void adjustFieldLayout 
             (LayoutContext layoutContext)
