Constructor Detail

ListItemRenderer

public ListItemRenderer(ListItem modelElement)

Creates a ListItemRenderer from its corresponding layout object.

Parameters:

modelElement - the ListItem which this object should manage

Method Detail

addSymbolRenderer

public void addSymbolRenderer(IRenderer symbolRenderer,
                              float symbolAreaWidth)

layout

public LayoutResult layout(LayoutContext layoutContext)

Description copied from interface: IRenderer

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 BlockRenderer

Parameters:

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

Returns:

result of the layout process

draw

public void draw(DrawContext drawContext)

Description copied from class: AbstractRenderer

Flushes the renderer subtree contents, i.e. draws itself on canvas, adds necessary objects to the PdfDocument etc.

Specified by:

draw in interface IRenderer

Overrides:

draw in class BlockRenderer

Parameters:

drawContext - contains the PdfDocument to which the renderer subtree if flushed, the PdfCanvas on which the renderer subtree is drawn and other additional parameters needed to perform drawing

getNextRenderer

public IRenderer getNextRenderer()

Description copied from class: DivRenderer

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.

Specified by:

getNextRenderer in interface IRenderer

Overrides:

getNextRenderer in class DivRenderer

Returns:

new renderer instance

createSplitRenderer

protected AbstractRenderer createSplitRenderer(int layoutResult)

Overrides:

createSplitRenderer in class BlockRenderer

createOverflowRenderer

protected AbstractRenderer createOverflowRenderer(int layoutResult)

Overrides:

createOverflowRenderer in class BlockRenderer
