protected AbstractRenderer |
createOverflowRenderer(int layoutResult)
Creates an overflow renderer.

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

LayoutResult |
layout(LayoutContext layoutContext)
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.

public LayoutResult layout(LayoutContext layoutContext)
BlockRenderer
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.
layout
in interface IRenderer
layout
in class BlockRenderer
layoutContext
- the description of layout area and any other additional information
public void draw(DrawContext drawContext)
AbstractRenderer
PdfDocument
etc.
draw
in interface IRenderer
draw
in class BlockRenderer
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
public IRenderer getNextRenderer()
DivRenderer
BlockRenderer.layout(LayoutContext)
is called more than once.
If a renderer overflows to the next area, iText uses this method to create a renderer for the overflow part. So if one wants to extend DivRenderer
, one should override this method: otherwise the default method will be used and thus the default rather than the custom renderer will be created.
