• paintComponent

  public void paintComponent(Graphics g)

  Description copied from class: JComponent
  Calls the UI delegate's paint method, if the UI delegate is non-null. We pass the delegate a copy of the Graphics object to protect the rest of the paint code from irrevocable changes (for example, Graphics.translate).

  If you override this in a subclass you should not make permanent changes to the passed in Graphics. For example, you should not alter the clip Rectangle or modify the transform. If you need to do these operations you may find it easier to create a new Graphics from the passed in Graphics and manipulate it. Further, if you do not invoker super's implementation you must honor the opaque property, that is if this component is opaque, you must completely fill in the background in a non-opaque color. If you do not honor the opaque property you will likely see visual artifacts.

  The passed in Graphics object might have a transform other than the identify transform installed on it. In this case, you might get unexpected results if you cumulatively apply another transform.

  Overrides:

  paintComponent in class JComponent

  Parameters:

  g - the Graphics object to protect

  JComponent.paint(java.awt.Graphics), ComponentUI

• getMinimumSize

  public Dimension getMinimumSize()

  Description copied from class: JComponent
  If the minimum size has been set to a non-null value just returns it. If the UI delegate's getMinimumSize method returns a non-null value then return that; otherwise defer to the component's layout manager.

  Overrides:

  getMinimumSize in class JComponent

  Returns:

  the value of the minimumSize property
