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. Best regards, Li Tsung Lin IAP Product Dept. Engineer EeRise Corp.
