Constructor Details

SelectFieldListBoxRenderer

 public SelectFieldListBoxRenderer 
             (AbstractSelectField modelElement) 
            

Creates a new SelectFieldListBoxRenderer instance.

Parameters:

modelElement - the model element

Method Details

getNextRenderer

 public IRenderer getNextRenderer() 
            

Description copied from interface: IRenderer

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

layout

 public LayoutResult layout 
             (LayoutContext layoutContext) 
            

Description copied from class: BlockRenderer

This method simulates positioning of the renderer, including all of its children, and returns the LayoutResult, representing the layout result, including occupied area, status, i.e. if there was enough place to fit the renderer subtree, etc. LayoutResult can be extended to return custom layout results for custom elements, e.g. TextRenderer uses TextLayoutResult as its result. This method can be called standalone to learn how much area the renderer subtree needs, or can be called before IRenderer.draw(DrawContext), to prepare the renderer to be flushed to the output stream.

Specified by:

layout in interface IRenderer

Overrides:

layout in class AbstractSelectFieldRenderer

Parameters:

layoutContext - the description of layout area and any other additional information

Returns:

result of the layout process

allowLastYLineRecursiveExtraction

 protected boolean allowLastYLineRecursiveExtraction() 
            

Overrides:

allowLastYLineRecursiveExtraction in class AbstractRenderer

createFlatRenderer

 protected IRenderer createFlatRenderer() 
            

Specified by:

createFlatRenderer in class AbstractSelectFieldRenderer

getFinalSelectFieldHeight

 protected float getFinalSelectFieldHeight 
             (float availableHeight, float actualHeight, boolean isClippedHeight) 
            

Overrides:

getFinalSelectFieldHeight in class AbstractSelectFieldRenderer

applyAcroField

 protected void applyAcroField 
             (DrawContext drawContext) 
            

Specified by:

applyAcroField in class AbstractSelectFieldRenderer
