Hi D L H, I'm guessing the browser you were testing on when you tried this out was Firefox 3? There is a known (and fixed) issue for this reported on the Issue Tracker. See Issue #2902 (link below). The fix for the issue has been committed all will be included in the next release.
Issue #2902: http://code.google.com/p/google-web-toolkit/issues/detail?id=2902 If you're working from the GWT trunk, you can pick up and patch the issue with r5398. Hope that helps, -Sumit Chandel On Mon, Jun 8, 2009 at 7:09 AM, D L H <[email protected]> wrote: > > hello. > > i'm trying to make a TextBox that will change value when someone > scrolls the mouse wheel over it. specifically, my goal is for the > number in the text box to increase when i scroll up, and decrease when > i scroll down. however, i'm having trouble figuring out the > MouseWheelHandler. i simplified my code to just change the value to > "UP" or "DOWN", but it just doesn't work. it compiles though. i also > tried it with event.preventDefault(), but that didn't seem to have any > effect. > > private TextBox valueField = new TextBox(); > ... > ... > valueField.addMouseWheelHandler(new MouseWheelHandler() { > public void onMouseWheel(MouseWheelEvent event) { > //event.preventDefault(); > if(event.isNorth()) { > valueField.setText("UP"); > } else { > valueField.setText("DOWN"); > } > } > }); > > > --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
