ListRenderer(List modelElement)
Creates a ListRenderer from its corresponding layout object.
|
| Modifier and Type | Method and Description |
|---|---|
protected AbstractRenderer |
createOverflowRenderer(int layoutResult)
Creates an overflow renderer.
|
protected AbstractRenderer |
createSplitRenderer(int layoutResult)
Creates a split renderer.
|
MinMaxWidth |
getMinMaxWidth()
Calculates min and max width values for current renderer.
|
IRenderer |
getNextRenderer()
Gets a new instance of this class to be used as a next renderer, after this renderer is used, if
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. |

BlockRendererLayoutResult, 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 IRendererlayout in class BlockRendererlayoutContext - the description of layout area and any other additional informationpublic IRenderer getNextRenderer()
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 ListRenderer, one should override
this method: otherwise the default method will be used and thus the default rather than the custom
renderer will be created.
