Mousewheel support under win9x

Nehal_Mistry · November 16, 2002, 11:27pm

Hi,

mousewheel doesn’t work for me under win9x,
only under linux…

the WM_MOUSEWHEEL message isn’t processed
under win9x, so i tried taking out the:

#if (_WIN32_WINNT >= 0x0400) || (_WIN32_WINDOWS > 0x0400)

from SDL_sysevents.c … because it should work
for win98 (although it doesnt for win95) i think
this may be a bug… this line should be fixed
to include win98/ME too… i dunno if
_WIN32_WINDOWS should be defined for win98 …
because it isn’t for me (im using mingw compiler)

… anyways:
i recompiled SDL and relinked my program
again… still same result… mousewheel doesn’t
work at all…

any clues?

Thx, Nehal

Can you scroll in other apps, like IE and stuff? If you cant, there is your
answer.On 16-Nov-2002, Nehal Mistry wrote:

What kind of question is that?
yes i can scroll under IE and other programs…
does anyone have any useful info/suggestions?>Can you scroll in other apps, like IE and stuff? If you cant, there is your

answer.

hi, this is sample of code: scrolling with wheel
will exit program in linux, but not in win98:

(i hope it pastes correctly)====================
#include
<SDL.h>
#include
<SDL_events.h>

int main(int argc, char
**argv)
{

SDL_Event

event;
SDL_Surface
*screen;

SDL_Init(SDL_INIT_EVERYTHING);
screen = SDL_SetVideoMode(640, 480, 16,
SDL_SWSURFACE);

SDL_LockSurface(screen);

for (;;)

{

SDL_WaitEvent(&event);
if (event.type ==
SDL_MOUSEBUTTONDOWN)

exit(0);

}

====================

maybe post the code where your trapping the mouse wheel event?

i dunno if
_WIN32_WINDOWS should be defined for win98 …
because it isn’t for me (im using mingw compiler)

It should (quoting MSDN):
Windows 98 _WIN32_WINDOWS >= 0x0410
Windows Me _WIN32_WINDOWS = 0x0490

…and probably
Windows 95 _WIN32_WINDOWS = 0x0400

Ciao,

There seems to be something touchy going on with MinGW
recompilation of the .dll. But that’s not the whole story.

I compiled your program under MinGW/MSYS on win98.

For me it works but shows the same odd behaviour I posted
about recently (with clarifications here):

the very first mousewheel event shows up immediately
(but only with the precompiled (VC?) version of the .dll)
subsequent mousewheel motions are not received until
some other event (like pointer motion or key press) occurs.
the delay problem goes away in fullscreen mode.

Your posted program exits after the first mousewheel event,
but SDL-1.2.5/test/graywin.c can be used to test the multiple
event delay and the fullscreen mode difference.

even if i get it working with dll… its something, but i cant…

I only get released or up events from the mouse wheels
so test with changing the code to test SDL_MOUSEBUTTONDOWN
instead.

I don’t know if that will work for Nehal, but using
SDL_MOUSEBUTTONUP doesn’t fix the delayed event queueing.

Nor does compiling entirely under VisualC, so it is not a MinGW
issue. Mousewheel events are broken in SDL-1.2.5 under win98.

This works fine for me, I’m running Windows 98 as well.
One thing that may be affecting your results. You’re not supposed to
keep the screen surface locked. Try removing that call and see if it
fixes the problem for you.

See ya!

Sam, do u have mingw? if u do can u test it on that please…

and if i remove the lock, the program automatically exits…
ie, the window popups for a split second, then exits…
(even if i take out the for loop)

thx, Nehal
