I want to be able to dynamically draw multiple rectangles dynamically onto a stage but I'm not sure how to go about doing that. What I was thinking was this:
1. When user clicks on screen, start drawing at x,y
2. Whenever the mouse moves, update the screen with the new x,y to get the rectangle (but if the user hasn't moved the mouse yet, keep the rectangle with height and width to be 0, 0).
3. Once user let's the mouse go, don't update the rectangle anymore.
But I want to also allow the user to change the width and height once they create the rectangle. And when the user clicks on the side of the ages, be able to change it that way too.
It would be exactly what they would have as selection tools in image editors. Any idea how to program out?
