I'm trying to make a hotkey type button which has a main image, a number in the top left indicating the hotkey button, and a number in the bottom right indicating the quantity of the item. I could use a Table to place these but they wouldn't be overlapping. I'd like to have the numbers on top of the main image so I used a stack, unfortunately it doesn't look like there's a way to control the actors on a stack - they all get placed at 0,0 within the biggest actor in the stack. Is there a way to place the actors in the appropriate positions or do I have to use table?
By definition, Stack puts its children in 0,0 coordinates and trying to stretch them to fill Stack.
You can use Group, for more control over actors you putting in:
You can simply get X and Y coordinates of inserted Actor by getX() and getY() methods. With little bit of help by getHeight() and getWidth() methods you can make simple table layout.
