copied!<p>I tried to make fully "event-transparent" (click-through as you call it) window, but there seems to be some native restrictions on that trick.</p> <p>Check this window example:</p> <pre><code>public static void main ( String[] args ) { Window w = new Window ( null ); w.add ( new JComponent () { protected void paintComponent ( Graphics g ) { g.setColor ( Color.BLACK ); g.fillRect ( 0, getHeight () / 2 - 10, getWidth (), 20 ); g.fillRect ( getWidth () / 2 - 10, 0, 20, getHeight () ); } public Dimension getPreferredSize () { return new Dimension ( 100, 100 ); } public boolean contains ( int x, int y ) { return false; } } ); AWTUtilities.setWindowOpaque ( w, false ); AWTUtilities.setWindowOpacity ( w, 0.5f ); w.pack (); w.setLocationRelativeTo ( null ); w.setVisible ( true ); } </code></pre> <p>Window and component does NOT have any:</p> <ol> <li>Mouse listeners</li> <li>Mouse motion listeners</li> <li>Mouse wheel listeners</li> <li>Key listeners</li> </ol> <p>Also the component should ignore any kind of mouse events EVEN if there are any listeners due to the modified <code>contains</code> method.</p> <p>As you can see - the area where nothing is painted on the component is event-transparent, but the filled area is not. Unluckly i didn't find any workaround to change that behavior. Seems that some "low-level" java methods are blocking the events.</p> <p>And this is just a basic JComponent-based example. I don't even say about more complex Swing components like labels, buttons e.t.c. which might have their own event-listeners which could block events.</p>
