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

[bruts@xxxxxxx]

Uri,

Would it be as simple as adding:

ioctl(uinput->fd, UI_SET_KEYBIT,  BTN_BACK);

ioctl(uinput->fd, UI_SET_KEYBIT,  BTN_FORWARD);

and re-compiling / testing?

I am not an experienced coder and have not had the time yet to get a good overview of the spice-vdagent code, so this might be a too simple approach.

I guess all of these values might be tested:

#define BTN_MISC        0x100
#define BTN_0            0x100
#define BTN_1            0x101
#define BTN_2            0x102
#define BTN_3            0x103
#define BTN_4            0x104
#define BTN_5            0x105
#define BTN_6            0x106
#define BTN_7            0x107
#define BTN_8            0x108
#define BTN_9            0x109

#define BTN_MOUSE        0x110
#define BTN_LEFT        0x110
#define BTN_RIGHT        0x111
#define BTN_MIDDLE        0x112
#define BTN_SIDE        0x113
#define BTN_EXTRA        0x114
#define BTN_FORWARD        0x115
#define BTN_BACK        0x116
#define BTN_TASK        0x117

Is there any way to test the btn value? Like xev is not showing me anything related to this value?

Your input is appreciated!

Thanks
