nanogui: Thread: API for refreshing windows under nanox ?

Hi all,

Who knows the API functions for refreshing windows
under nanox? Or how to post a message, like EXPOSURE,
make it refresh automatically?

Any help is appreciated.

I'm not quite sure what you're asking, but if you want to force another 
window to redraw, you can do:
    GrClearArea(wid, 0, 0, 0, 0, GR_TRUE);
Where wid is the ID of the window to clear and generate an exposure 
event for. This isn't something you normally need to do as exposure 
events are generated automatically when part of a window is exposed.
