Re: Mac OS X: Problems with custom widget in JTable

I am using a simple "graph widget" (a subclass of JComponent that

JTable.
This works fine on Linux and Windows (you see the /\ /\ in each cell),
but on Mac OS X (also with Java 1.6) the cells are empty (just plain
white window).
Others have addressed the main points, but I see another problem - you aren't
doing GUI on the Event Dispatch Thread (EDT).
public static void main(String[] args) {
TestJTable5 frame = new TestJTable5();
frame.addWindowListener( new WindowAdapter() {
public void windowClosing( WindowEvent e ) {
System.exit(0);
}
});
//frame.pack();
frame.setVisible(true);
}
All those GUI calls and constructors should be moved to the EDT, most easily
by using java.awt.EventQueue.invokeLater() of a new Runnable around the calls
in your main().
