I have a slider that I use for color selection, and have the live scroll property set to true so that as I move the slider, the color of a small rectangle changes color. That works fine. However, when I release the slider, I'd like a complex image to update in a canvas. That process takes a second or two, so it's not practical to include that in the value changed event of the slider. I thought that maybe I could use the mouse up event in the slider to trigger the canvas redraw, but it appears that mouse button events are not compatible with the slider. The language reference says that in order to use the mouse up event, then the mouse down event must be set to return true. If I add the mouse down event and have it return true, then the slider control won't do anything when I try to move it. It's frozen.
Is there some other way to achieve what I'm trying to do here?
