Testing for Looks

We have a properly connected panel. We can check the widgets'relative locations:

• label left-of queryField

• queryField left-of findButton

• queryField above table

To make this test run, we need to put our panel in a frame or window. (Components don't have their screen locations set until their containing window is created.)

 public void testRelativePosition() { SearchPanel sp = new SearchPanel(); JFrame display = new JFrame("test"); display.getContentPane().add(sp); ...
