How do i do it?
I have no idea what you are talking about. Transparency can means a hundred things.
Please be more clear and explain in lengthy and clear details what you would like to do, the context etc. This is the minimum amount of respect expected if you wish to obtain an answer.
I mean the transparency on the window
Closing this until you can make full sentences.
Please run the example code, read the docs and comments on ImGuiStyle and ImGui::Begin().
Regards.
Where is the docs and the example code? I can't even find it lol
