I’ve used DirectGUI so far and not that it is bad, but I do believe the skinning with your own textures is a mess and I also don’t understand why it is in Python.
I think DirectGUI can do everything and look like the GUI from your picture, it’s just time consuming to configure it to look that way and maybe it’s a bit slower.
Could you please list some advantages or improvements over DirectGUI? Is it just the skinning or is there more? Thanks.
