Graphics Context #121

Closed drb4637 closed 1 day ago

drb4637 commented 5 months ago

Hi My application has a few different graphics contexts and I noticed after switching context the glwpf control stops updating. Adding a check inside GLWpfControlRenderer.Render to make sure that the graphics context is current fixes the issue but I was wondering if there was a better way to handle multiple contexts?

What version of GLWpfControl are you using? Could you describe your issue in more detail?

How does the updates stop? Does the render function stop being called?

NogginBops commented 2 days ago

Changing the thread the GLWpfControls context is current on is going to be pretty problematic as you can't really synchronize when to make it current on the rendering thread. With #86 you are able to setup context sharing between contexts which is likely a better solution.

Hi, sorry for the delayed response. Yea the context sharing seems to fix my issue. Also nice you got MSAA working, gone are the days of bliting the frame buffer :D

Good to hear! I'll close this issue then. :)
