Constructor Detail

FlexContainerRenderer

public FlexContainerRenderer(Div modelElement)

Creates a FlexContainerRenderer from its corresponding layout object.

Parameters:

modelElement - the Div which this object should manage

Method Detail

getNextRenderer

public 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.

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 FlexContainerRenderer, one should override this method: otherwise the default method will be used and thus the default rather than the custom renderer will be created.

Specified by:

getNextRenderer in interface IRenderer

Overrides:

getNextRenderer in class DivRenderer

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

getMinMaxWidth

public MinMaxWidth getMinMaxWidth()

Calculates min and max width values for current renderer.

Overrides:

getMinMaxWidth in class BlockRenderer

Returns:

instance of MinMaxWidth

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
