16 | Abstract:\r | |
17 | \r | |
18 | This file produces the Simple Text In for an Gop window.\r | |
19 | \r | |
20 | This stuff is linked at the hip to the Window, since the window\r | |
21 | processing is done in a thread kicked off in WinNtGopImplementation.c\r | |
22 | \r | |
23 | Since the window information is processed in an other thread we need\r | |
24 | a keyboard Queue to pass data about. The Simple Text In code just\r | |
25 | takes data off the Queue. The WinProc message loop takes keyboard input\r | |
26 | and places it in the Queue.\r | |
