Re: spice-vdagent: how to enable additional mouse buttons?

[bruts@xxxxxxx]

Hi,

Yes most likely.

I find these lines of code:

/* buttons */
    ioctl(uinput->fd, UI_SET_EVBIT, EV_KEY);
    ioctl(uinput->fd, UI_SET_KEYBIT, BTN_LEFT);
    ioctl(uinput->fd, UI_SET_KEYBIT, BTN_MIDDLE);
    ioctl(uinput->fd, UI_SET_KEYBIT, BTN_RIGHT);

    /* wheel */
    ioctl(uinput->fd, UI_SET_EVBIT, EV_REL);
    ioctl(uinput->fd, UI_SET_RELBIT, REL_WHEEL);

I will probably need to declare the additional mouse buttons of my mouse (Logitech G403), so I run xev to find some information:

(BTN_LEFT, BTN_RIGHT, button 8, button 9)

ButtonPress event, serial 48, synthetic NO, window 0x3000001,
    root 0x3ad, subw 0x0, time 361327, (127,94), root:(128,144),
    state 0x0, button 1, same_screen YES

ButtonRelease event, serial 48, synthetic NO, window 0x3000001,
    root 0x3ad, subw 0x0, time 361426, (127,94), root:(128,144),
    state 0x100, button 1, same_screen YES

ButtonPress event, serial 48, synthetic NO, window 0x3000001,
    root 0x3ad, subw 0x0, time 362448, (127,94), root:(128,144),
    state 0x0, button 3, same_screen YES

ButtonRelease event, serial 48, synthetic NO, window 0x3000001,
    root 0x3ad, subw 0x0, time 362556, (127,94), root:(128,144),
    state 0x400, button 3, same_screen YES

ButtonPress event, serial 48, synthetic NO, window 0x3000001,
    root 0x3ad, subw 0x0, time 366829, (127,94), root:(128,144),
    state 0x0, button 8, same_screen YES

ButtonRelease event, serial 48, synthetic NO, window 0x3000001,
    root 0x3ad, subw 0x0, time 366949, (127,94), root:(128,144),
    state 0x0, button 8, same_screen YES

ButtonPress event, serial 48, synthetic NO, window 0x3000001,
    root 0x3ad, subw 0x0, time 368093, (127,94), root:(128,144),
    state 0x0, button 9, same_screen YES

ButtonRelease event, serial 48, synthetic NO, window 0x3000001,
    root 0x3ad, subw 0x0, time 368250, (127,94), root:(128,144),
    state 0x0, button 9, same_screen YES

Now the next question is obvious: how do I adjust the code to add support for button 8,9 ?

I thought BTN_LEFT and BTN_RIGHT would be declared in uinput.h but they are global variables? or where are they declared?

Any help with adding support for these buttons would be very appreciated and finally make me stop using virtualbox lol.

Thanks!
