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