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.
