Hey all,
I have two questions and one suggestion:
Q1: How far along are things for multiple windows? (time-wise) Q2: Will multiple windows open the door to render to a texture as if it was just another window? (I can think of many uses for this in relation to pixelTANGO)
Suggestion:
What if there is a gemwin outlet that deals with all input events, keyboard, mouse etc.. The format could follow the HID format, which would mean that abstractions made to work with HID would be fully compatible with Gem window events... I think this would be very nice to share the same format to get the data. I'm sure there are some ugly implications of saying this but I think it would be nice to be able to use the same abstractions to parse/smooth and genrally work with input data (tablet, mouse, keyboard etc..)
