Child Window?

Hi! I’m trying to construct a 3D editor, and I’m getting some problems…

I’m using the win32api (no MFC) to make them menu, toolbars, etc…
The problem is that OpenGL draw the things under my toolbar… Because its share the same Handle… Now, I thing I have to create another window, with another Handle, so I can draw to it, without erasing the actual content of Principal Handle.

I’m new to win32 API, and I would like to know How I’m going to do this!!!

I want to use Win32API! (no MFC, no glut).

DO I have to create a CHILD WINDOW or I can Create just a simple ‘Panel’ (like TPanel on Delphi) without having to configure a MDI Client, etc?

Thank you guys!
