Could you post more code?  Where are you calling the code you have shown us?  It sounds to
me like you would need a flag set on key down or mouse down, and cleared on key up or mouse
up, and then only do the zoom as you have shown while the flag is set.  But, without a bit
more of an idea of how you have structured things, it is a little hard to tell.

Thanks,

Subject: Re: Zooming an image

Hello, my name is Javier

At first, i think is a good idea to resize the container BoxPane, in order to execute zoom,
with image setted to fill.

But here is a problem: the zoom only sets after mousemove or similar (panel is a BoxPane containing
an image):

                int newWidth=(int)((float) panel.getWidth() * zoomXY);
                int newHeight=(int)((float) panelgetHeight() * zoomXY);
                               
                panel.setPreferredWidth(newWidth);
                panel.setPreferredHeight(newHeight);

Now, the zoom only ends when moving the mouse or keyboard click.

┬┐Any idea?

Thanks
