How was VGUI made? Valve made their own GUI library called VGUI. I am wondering how were they able to make their GUI library and what methods they used to make it. Did they use Win32 API or something else. Is there an open source code for VGUI? Please answer these questions and help me out as much as you can. https://ift.tt/eA8V8J
