      • 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 AbstractFormFieldRenderer
        Parameters:
        layoutContext - the description of layout area and any other additional information
        Returns:
        result of the layout process

      • getProperty

        public <T1> T1 getProperty​(int key)
        Gets the property from this entity. Compared to IPropertyContainer.getOwnProperty(int), this method can check parent's properties, styles, etc, depending on the origin of the instance
        Specified by:
        getProperty in interface IPropertyContainer
        Overrides:
        getProperty in class AbstractRenderer
        Type Parameters:
        T1 - the return type associated with the property
        Parameters:
        key - the property to be retrieved
        Returns:
        the value of the given property. null will be returned if the property value was not found
