-Module Name:
-
- UnixUgaInput.c
-
-Abstract:
-
- This file produces the Simple Text In for an Uga window.
-
- This stuff is linked at the hip to the Window, since the window
- processing is done in a thread kicked off in UnixUgaImplementation.c
-
- Since the window information is processed in an other thread we need
- a keyboard Queue to pass data about. The Simple Text In code just
- takes data off the Queue. The WinProc message loop takes keyboard input
- and places it in the Queue.
