Fixed bug #61
Date: Mon, 24 Feb 2003 13:35:11 +0800
From: "Leonidas"
Subject: [SDL] Re: Trigger mouse wheel event -- not in X-environment
I have looked into the codes for the IMPS/2 mouse wheel mode of fbcon driver.
But I found something weird.
Here's the original codes to set a mouse device into IMPS/2 mode in libSDL.
In the file src/video/fbcon/SDL_fbevents.c
In function static int set_imps2_mode(int fd)
...
Uint8 set_imps2[] = {0xf3, 200, 0xf3, 100, 0xf3, 80};
Uint8 reset = 0xff;
fd_set fdset;
struct timeval tv;
int retval = 0;
// Set mouse device fd into IMPS/2 mode
if ( write(fd, &set_imps2, sizeof(set_imps2)) == sizeof(set_imps2) ) {
// ??? then RESET it..???
if (write(fd, &reset, sizeof (reset)) == sizeof (reset) ) {
retval = 1;
}
}
...........
Since it sets IMPS/2 mode then reset it, so you will never get a mouse into
IMPS/2 mode to use its wheel.
What I did to make the wheel usable is remove the RESET codes.
....
if ( write(fd, &set_imps2, sizeof(set_imps2)) == sizeof(set_imps2) ) {
/*
if (write(fd, &reset, sizeof (reset)) == sizeof (reset) ) {
}
*/
retval = 1;
}
....
And in FB_OpenMouse(_THIS)
Make the device /dev/psaux to be setted into imps2 mode such that it can be
detected its a imps/2 mouse or not.
(my mouse device is on ps2, but the codes only set /dev/input/mice device
originally)
Then I have done, I can use the mouse wheel when SDL uses frame buff driver.
I dont exactly know I did right or wrong, I just change it for my usuage.
Correct me please, if I did something wrong.

| 3 Using the Simple DirectMedia Layer with MacOS 7,8,9 on PPC | |
| 4 ============================================================================== | |
| 5 | |
| 6 These instructions are for people using the Apple MPW environment: | |
| 7 http://developer.apple.com/tools/mpw-tools/ | |
| 8 | |
| 9 CodeWarrior projects are available in the CWprojects directory. | |
| 10 | |
| 11 ============================================================================== | |
| 12 I. Building the Simple DirectMedia Layer libraries: | |
| 13 (This step isn't necessary if you have the SDL binary distribution) | |
| 14 | |
| 15 First, unpack the MPWmake.sea.hqx archive and move SDL.make into the | |
| 16 SDL directory. | |
| 17 | |
| 18 Start MPW | |
| 19 | |
| 20 Set the current directory within MPW to the SDL toplevel directory. | |
| 21 | |
| 22 Build "SDL" (Type Command-B and enter "SDL" in the dialog) | |
| 23 | |
| 24 If everything compiles successfully, you now have the PPC libraries | |
| 25 "SDL" and "SDLmain.o" in the 'lib' subdirectory. | |
| 26 | |
| 27 ============================================================================== | |
| 28 II. Building the Simple DirectMedia Layer test programs: | |
| 29 | |
| 30 First, unpack the MPWmake.sea.hqx archive, move the new rsrc directory to | |
| 31 the main SDL directory, and move the makefiles in the new test subdirectory | |
| 32 to the SDL 'test' subdirectory. | |
| 33 | |
| 34 Start MPW | |
| 35 | |
| 36 Set the current directory within MPW to the SDL 'test' subdirectory. | |
| 37 | |
| 38 Build the programs that have an associated MPW makefile (file ending | |
| 39 with .make), including "testwin", "testalpha", and "graywin". | |
| 40 | |
| 41 Copy the SDL library file into the test directory, and run! | |
| 42 | |
| 43 ============================================================================== | |
| 44 III. Building the Simple DirectMedia Layer demo programs: | |
| 45 | |
| 46 Copy one of the test program Makefiles to the demo directory | |
| 47 and modify it to match the sources in the demo. | |
| 48 | |
| 49 ============================================================================== | |
| 50 IV. Enjoy! :) | |
