Mouse Down On Image but Not On Scrollbar Event?

Go to solution

Hi All,


I am using a "Mouse Down" event on an image to record the X and Y coordinates of the click and to increment a counter.  My problem is that I am looking at an image with a scroll bar that I want to use to adjust which part of the image is visible.  When I click on the scroll bar, I trigger the Mouse Down event and increment the counter, which I do not want to do.

Is there a way to set up a Mouse Down event so that it will ignore clicks on image scroll bars?  If not, can you think of another way to accomplish what I am trying to do?

A couple quick ideas:

The scroll bars will be a fixed height or width from the right side or bottom of the indicator. In the mouse down event handler, if the click occurs at a set of coordinates that you know are in a scrollbar region, don't increment the count.


Perhaps you could overlay a transparent control over the image such that it covers the image but not the scrollbars, then look for clicks on that second control.

That worked perfectly.  Thanks!  I used the Coords indicator in the event handler to define the area where mouse clicks "count."

You can do this dynamically with these property nodes:



"DrawAreaSize" will give you the draw are size of the picture excluding scrollbars, the "Mouse"-cluster contains information of the mouse position within the picture control (starting at 0,0). Hence X & Y position have to be smaller than "width" and "height" of the draw area in order to count as a valid click.
