Thanks to the magic of the Internet, I figured out how to add a tab with a "camera widget" and an image overlay. I would like to improve it a little... There are three buttons and I would like the button click to change the image used for the camera overlay.
Something like: btnOverlay3.onClick -> videoDisplay.image = "someimage.png"
Obviously I have no idea what the code needs to look like or where it goes. I'm guessing that there would need to be a function in some script and then the name of that function goes into the button event. I posted this to the "video probing" category because that is the goal, but maybe there is a better choice?
Thanks in advance for your help.
