Hi,

I believe this is a OS X specific bug:

import org.eclipse.swt.SWT;
import org.eclipse.swt.events.MouseEvent;
import org.eclipse.swt.events.MouseListener;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.widgets.*;

public class MouseBug implements MouseListener
{
public static void main(String[] args)
{
Display display = Display.getDefault();
Shell shell = new Shell(display);
shell.setLayout(new FillLayout());
shell.setSize(100,100);
MouseBug mousebug = new MouseBug();

// works correctly under OS X
// mouse pressed: mouse up event generated
// mouse released: mouse down event generated
// double click: 2 x up, down, and 1 x double click
// event generated
Canvas canvas = new Canvas(shell, SWT.NONE);
canvas.addMouseListener(mousebug);

// doesn't work as expected under OS X:
// mouse pressed: nothing happens
// mouse released: mouse down event generated
// double click: works (same as canvas)
Button button = new Button(shell, SWT.NONE);
button.addMouseListener(mousebug);

shell.pack();
shell.open();

while (!shell.isDisposed())
{
if (!display.readAndDispatch())
display.sleep();
}
}

public void mouseDoubleClick(MouseEvent arg0)
{
System.out.println("mouse double click");
}

public void mouseDown(MouseEvent arg0)
{
System.out.println("mouse down");
}

public void mouseUp(MouseEvent arg0)
{
System.out.println("mouse up");
}
}

Thanks
Jelle
