    • Method Detail

      • getNextRenderer

        public IRenderer getNextRenderer()
        Description copied from interface: IRenderer
        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)
        Description copied from class: AbstractSelectFieldRenderer
        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 AbstractSelectFieldRenderer
        Parameters:
        layoutContext - the description of layout area and any other additional information
        Returns:
        result of the layout process
      • getFinalSelectFieldHeight

        protected float getFinalSelectFieldHeight​(float availableHeight,
                                                  float actualHeight,
                                                  boolean isClippedHeight)
        Description copied from class: AbstractSelectFieldRenderer
        Returns final height of the select field.
        Overrides:
        getFinalSelectFieldHeight in class AbstractSelectFieldRenderer
        Parameters:
        availableHeight - available height of the layout area
        actualHeight - actual occupied height of the select field
        isClippedHeight - indicates whether the layout area's height is clipped or not
        Returns:
        final height of the select field.
      • getCalculatedHeight

        private float getCalculatedHeight​(IRenderer flatRenderer)
      • getMaxOptionActualHeight

        private float getMaxOptionActualHeight​(IRenderer flatRenderer)
      • getSelectedOptions

        private java.util.List<IRenderer> getSelectedOptions​(IRenderer rendererSubTree)
      • isMultiple

        private boolean isMultiple()
      • applySelectedStyle

        private void applySelectedStyle​(IRenderer selectedOption)
      • setFontColorRecursively

        private void setFontColorRecursively​(IRenderer selectedOption)
        The `select` tag has default color css property, therefore it makes sense to explicitly override this property to all children, otherwise it will be not applied due to the css resolving mechanism.
