public class WrappingIconPanel extends JXPanel implements PainterAware, IconAware
Compound component for usage in tree renderer.

Supports setting an icon for the node and a delegate component which is used to show the text/content of the node. The delegate component can be shared across renderers.

This implements the PainterAware by delegating to the delegate component if that is of type PainterAware. Does nothing if not.

    • setComponentOrientation

      public void setComponentOrientation(ComponentOrientation o)

      Overridden to update the icon position.

      Overrides:
      setComponentOrientation in class Component

    • setIcon

      public void setIcon(Icon icon)
      Sets the icon.
      Specified by:
      setIcon in interface IconAware
      Parameters:
      icon - the icon to use.

    • getIcon

      public Icon getIcon()
      Returns the icon used in this panel, may be null.
      Specified by:
      getIcon in interface IconAware
      Returns:
      the icon used in this panel, may be null.

    • setComponent

      public void setComponent(JComponent comp)
      Sets the delegate component.
      Parameters:
      comp - the component to add as delegate.

    • getComponent

      public JComponent getComponent()
      Returns the delegate component.
      Returns:
      the delegate component.

    • setBackground

      public void setBackground(Color bg)

      Overridden to set the background of the delegate and icon label as well.

      Overrides:
      setBackground in class JComponent

    • setForeground

      public void setForeground(Color bg)

      Overridden to set the foreground of the delegate and icon label as well.

      Overrides:
      setForeground in class JComponent

    • setFont

      public void setFont(Font font)

      Overridden to set the Font of the delegate as well.

      Overrides:
      setFont in class JComponent

    • isVisible

      public boolean isVisible()

      Overridden to hack around #766-swingx: cursor flickering in DnD when dragging over tree column. This is a core bug (#6700748) related to painting the rendering component on a CellRendererPane. A trick around is to let this return false.

      Some LayoutManagers don't layout an invisible component, so need to make the hack-enabled configurable. This implementation will return false if isDropHackEnabled, super.isVisible otherwise.

      Overrides:
      isVisible in class Component

    • getPainter

      public Painter<?> getPainter()

      Returns the delegate's Painter if it is of type PainterAware or null otherwise.

    • getDelegateBounds

      public Rectangle getDelegateBounds()
      Returns the bounds of the delegate component or null if the delegate is null. PENDING JW: where do we use it? Maybe it was for testing only?
