        public ListRenderer​(List modelElement)

    • Method Detail

      • layout

        public LayoutResult layout​(LayoutContext layoutContext)
        Description copied from class: BlockRenderer
        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
      • 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 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.

        Returns:
        new renderer instance
