Constructor	Description
GridContainerRenderer(GridContainer modelElement)	Creates a Grid renderer from its corresponding layout object.

Method Summary

Modifier and Type	Method	Description
void	addChild(IRenderer renderer)	Adds a child to the current renderer
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.

Constructor Details

GridContainerRenderer

             public GridContainerRenderer
             (GridContainer modelElement)
            

Creates a Grid renderer from its corresponding layout object.

Parameters:

modelElement - the GridContainer which this object should manage

Method Details

getNextRenderer

             public 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.

Returns:

new renderer instance

layout

             public 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. 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

addChild

             public void addChild
             (IRenderer renderer)
            

Adds a child to the current renderer

Specified by:

addChild in interface IRenderer

Overrides:

addChild in class AbstractRenderer

Parameters:

renderer - a child to be added
