Hi,
Thanks for the suggestion and Im trying it out with pgu. Now Im having
problems with the pgu interface. Can anyone help me?
I've attached my test code. Its basically a button or event that brings
up a text entry dialog. So far its fine, as soon as the dialog is
closed, it wont close. Any ideas?
Cheers
Stan

hi,
Lamina allows you to use any pygame 2d gui with opengl.

It's fairly easy to use, and comes with demos for ocempgui and pgu.
cheers,

Hi,
I was wondering if there is a way to get a simple text entry dialog on a
pygame+opengl surface. I've tried several and all of them seem to dislike
doing a .blit on a opengl surface and crash badly whenever I do anything on
it. Are there simple alternatives?
Thanks
Astan
