public class JRendererCheckBox extends JCheckBox implements PainterAware
A JCheckBox optimized for usage in renderers and with a minimal background painter support.

Note: As of revision #4223, there's a complete overhaul (aka: changed the tricksery) to fix Issue swingx-1513 (allow client code to set renderer transparent) while keeping fix Issue swingx-897 (striping/background lost when painter installed)

Note: The change of logic _did_ introduce a regression (swingx-1546) which was fixed by forcing the box's opacity to true (for regression release 1.6.5-1). Further improvements (like f.i. the option to delegate to the ui's update - to allow LAF installed painters - instead of paint) are deferred to a later normal release, more discussions needed.

  • Field Details

    • painter

      protected Painter painter
      the swingx painter

    • fakeTransparency

      private boolean fakeTransparency
      a flag to prevent ui painting from filling the background.

  • Constructor Details

    • JRendererCheckBox

      public JRendererCheckBox()
      Instantiates a JRendererCheckBox with opacity true.

  • Method Details

    • getPainter

      public Painter getPainter()
      Specified by:
      getPainter in interface PainterAware

    • setPainter

      public void setPainter(Painter painter)
      Specified by:
      setPainter in interface PainterAware

    • isOpaque

      public boolean isOpaque()

      Overridden to return false if painting flag is true.

      Overrides:
      isOpaque in class JComponent

    • isContentAreaFilled

      public boolean isContentAreaFilled()

      Overridden to return false if painting flag is true.

      Overrides:
      isContentAreaFilled in class AbstractButton

    • setToolTipText

      public void setToolTipText(String text)

      Overridden to not automatically de/register itself from/to the ToolTipManager. As rendering component it is not considered to be active in any way, so the manager must not listen.

      Overrides:
      setToolTipText in class JComponent

    • paintComponent

      protected void paintComponent(Graphics g)
      Overridden to snatch painting from super if a painter installed or Nimbus detected.

      The overall logic currently (since 1.6.5) is to simply call super without SwingX painter. Otherwise, that is with SwingX painter:

      1. if opaque
        1. set a flag which fakes transparency, that is both contentAreaFilled and opaque return false
        2. fill background with the component's background color
        3. apply swingx painter
        4. hook into ui.paint(...)
        5. reset the flag
      2. else
          apply swingx painter
            call super
            Note that Nimbus is special cased (mainly due to its bug of even row striping instead of odd) and handled as if a SwingX painter were set.
      Overrides:
      paintComponent in class JComponent

    • isNimbus

      private boolean isNimbus()
      Hack around Nimbus not respecting background colors if UIResource. So by-pass ...
      Returns:

    • paintPainter

      private void paintPainter(Graphics g)
      Hack around AbstractPainter.paint bug which disposes the Graphics. So here we give it a scratch to paint on.

      TODO - remove again, the issue is fixed?

      Parameters:
      g - the graphics to paint on

    • paintComponentWithPainter

      protected void paintComponentWithPainter(Graphics2D g)
      Parameters:
      g -
