Examples of java.awt.Container.invalidate()

java.awt.Container.invalidate()
Invalidates the container. The container and all parents above it are marked as needing to be laid out. This method can be called often, so it needs to execute quickly.
If the {@code LayoutManager} installed on this container isan instance of {@code LayoutManager2}, then {@link LayoutManager2#invalidateLayout(Container)} is invoked onit supplying this {@code Container} as the argument. @see #validate @see #layout @see LayoutManager @see LayoutManager2#invalidateLayout(Container)

  //this method fixes dumb repaint issues
  //when components are updated
  private void forceRepaint()
  {
    final Container contentPane = getContentPane();
    contentPane.invalidate();
    contentPane.validate();
    contentPane.repaint();
  }
