Creating a drag rectangle on the thick client
I’m working on a feature where I want the user to be able to draw a rectangle onto an image on a window in the runtime. At the moment it’s pretty basic – I can track the mouse down and mouse up events, and then it draws the box. However, it would be really cool if the user saw a rectangle as they moved the mouse after clicking mouse down – like drawing a box in a drawing program. For double bonus points it’d be awesome if they could later on select the rectangle and resize it.
I don’t think there’s any functionality in Omnis that allows us to do that in the runtime. Has anyone done something like this in the past, and are willing to share?
