MouseWheelZoomEventHandler doesnt stop zooming #257

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem? What is the expected output? What do you 
see instead?
Using a mouseWheelRotated/ mouseWheelZoomEventHandler causes the 
panel/scrollpane/swing/canvas to be zoomed very deep. The reason being is that 
it doesnt stop zooming after stopping to rotate the mouse wheel. Instead it 
keeps zooming until the x value is NaN.

What version of the product are you using? On what operating system?
Piccolo2D 3.0 on Xubuntu

I used following code to add a mouse wheel zoom event handler:

canvas.removeInputEventListener(canvas.getZoomEventHandler());

final PMouseWheelZoomEventHandler mouseWheelZoomEventHandler = new 
PMouseWheelZoomEventHandler();
canvas.addInputEventListener(mouseWheelZoomEventHandler);
