Subject: [SDL] Re: Modifier keys pressed during initialization stick
I wrote a simple test program which initializes SDL, prints the SDL
version number, then prints any keydown and keyup events with their
modifiers. (Source code below). Compilation was done using Visual
Studio 6, release mode.
My test sequence was:
Start a command prompt. Type the name of the test program.
shift down
enter down (program starts)
Wait for window to appear
enter up
shift up
spacebar down
spacebar up
Under Windows 98, the output was correct:
SDL 1.2.8
left shift down
shift-return down
shift-return up
left shift up
space down
space up
Under Windows 2000 and under Windows XP, the output was:
SDL 1.2.8
shift-space down
shift-space up
Since shift was not held at the time space was pressed, this is
incorrect. Similar results were observed with launching in different
ways (including double-clicking in Windows Explorer), so it does not
depend on the launching terminal.

55 We compile SDL into a DLL on OS/2. This means, that it's the DLL which | |
56 creates a new thread for the calling process with the SDL_CreateThread() | |
57 API. There is a problem with this, that only the RTL of the SDL.DLL will | |
58 be initialized for those threads, and not the RTL of the calling application! | |
59 To solve this, we make a little hack here. | |
60 We'll always use the caller's _beginthread() and _endthread() APIs to | |
61 start a new thread. This way, it it's the SDL.DLL which uses this API, | |
62 then the RTL of SDL.DLL will be used to create the new thread, and if it's | |
63 the application, then the RTL of the application will be used. | |
64 So, in short: | |
