void |
drawChildren(DrawContext drawContext)
Performs the drawing operation for all children of this renderer.

|
getDefaultProperty(int property)
Gets the default property from this entity.
|
protected Float |
getFirstYLineRecursively()
Gets the first yLine of the nested children recursively.
|
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.
|
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)
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.
