      hasChildPostscripts in interface JEuclidElement
      Overrides:
      hasChildPostscripts in class AbstractJEuclidElement
      Parameters:
      child - child to test
      context - current layout context.
      Returns:
      true if there are attached postscripts

    • layoutStageInvariant

      protected void layoutStageInvariant(LayoutView view, LayoutInfo info, LayoutStage stage, LayoutContext context)
      Layout for elements which are stage independent.

      This function will layout an element which is layed out the same no matter what stage it is in. This is the case for most elements.

      Notable exceptions are mo and tables.

      Overrides:
      layoutStageInvariant in class AbstractJEuclidElement
      Parameters:
      view - View Object for this layout.
      info - An info object which will be filled during layout.
      stage - current layout stage.
      context - current LayoutContext.
