Hello all,
In the application I am developing I need to let the user do the following;
press leftMouseButton down, drag, then leftMouseBottomUp -> display popup
menu
That is, the popup menu needs to be displayed after the user releases the
left mouseButton. Does anyone know if this is possible at all in SWT? I have
looked everywhere, but all the sites/book I have consulted don't help...
I've really hit a brick wall here, and am starting to wonder if this is
possible at all.
Any thanks is much appreciated.
Thanks.

public static void main (String [] args) {
Display display = new Display ();
Shell shell = new Shell (display);
final Menu menu = new Menu(shell, SWT.POP_UP);
MenuItem item = new MenuItem (menu, SWT.PUSH);
item.setText ("Hello");
shell.addMouseListener(new MouseAdapter() {
Point mouseDown;
public void mouseDown(MouseEvent e) {
if (e.button == 1) {
mouseDown = new Point(e.x, e.y);
}
}
public void mouseUp(MouseEvent e) {
if (e.button == 1) {
if (Math.abs(mouseDown.x - e.x) > 2 ||
Math.abs(mouseDown.y - e.y) > 2) {
menu.setVisible(true);
}
}
mouseDown = null;
}
});
shell.open ();
while (!shell.isDisposed ()) {
if (!display.readAndDispatch ()) display.sleep ();
}
display.dispose ();
}
