Member Function Documentation

◆ CreateRendererSubTree()

IRenderer iText.Layout.Element.IElement.CreateRendererSubTree ( )

Creates a renderer subtree with root in the current element.

Creates a renderer subtree with root in the current element. Compared to GetRenderer() , the renderer returned by this method should contain all the child renderers for children of the current element.

Returns
a renderer subtree for this element

Implemented in iText.Layout.Element.Table, and iText.Layout.Element.AbstractElement< T >.

◆ GetRenderer()

IRenderer iText.Layout.Element.IElement.GetRenderer ( )

Gets a renderer for this element.

Gets a renderer for this element. Note that this method can be called more than once. By default each element should define its own renderer, but the renderer can be overridden by SetNextRenderer(iText.Layout.Renderer.IRenderer) method call.

Returns
a renderer for this element

Implemented in iText.Layout.Element.Table, and iText.Layout.Element.AbstractElement< T >.

◆ SetNextRenderer()

void iText.Layout.Element.IElement.SetNextRenderer ( IRenderer  renderer )

Overrides the iText.Layout.Renderer.IRenderer instance which will be returned by the next call to the GetRenderer().

Parameters
renderer the renderer instance

Implemented in iText.Layout.Element.AbstractElement< T >.
