touchscreen no work with sdl + drm about lvgl HOT 8 CLOSED

I've checked in SDL's docs that for SDL_FINGER* events really event->tfinger shall be used. If SDL doesn't set the Window ID we cannot do much.

Can you ask it from the SDL developers?

I'm use is in DRM not X11, maybe these two are different.

/*Find a suitable indev*/
    lv_indev_t * indev = lv_indev_get_next(NULL);
    while(indev) {
        if(disp != NULL) {
            if(lv_indev_get_display(indev) == disp) {
                break;
            }
        }
        if(lv_indev_get_type(indev) == LV_INDEV_TYPE_POINTER) {
            break;
        }
        indev = lv_indev_get_next(indev);
    }

I have modified the lv_sdl_mouse.c code, that it can work properly.
after:
I found that my code was written incorrectly, and I have corrected it.

What is the difference? It seems to your code does the same thing, just the if is split into 2 parts. Am I missing something?

from lvgl.

In drm, disp is null, but lv_indev_get_display(indev) is not null.

from lvgl.

This way always the first POINTER indev will be found. Which is better nothing, but worth mentioning.

I've opened #6194 to fix it.

from lvgl.

I have tested it, this patch is work.

Great, thank you!
