This enables + Linux guests to seamlessly integrate, i.e. the pointer doesn't have to be + captured by the guest anymore. + +Pointer movement, all five buttons (two of them being mapped to 'middle') and both vertical and horizontal wheels are supported. + +Vertical mouse wheel functionality could be verified using links in framebuffer mode. Horizontal wheel is untested due to the lack of a device with that feature. +--- + src/mice.c | 59 ++++++++++++++++++++++++++++++++++++++++++++++++++++++ + 1 file changed, 59 insertions(+) + +diff --git a/src/mice.c b/src/mice.c +index 6cbd491..00c69b9 100644 +--- a/src/mice.c ++++ b/src/mice.c +@@ -254,6 +254,62 @@ static int M_evdev (Gpm_Event * state, unsigned char *data) + } + return 0; + } ++ ++/* ++ * USB Tablet emulated by VirtualBox for seamless mouse integration ++ * ++ * The 'VirtualBox USB Tablet' is an absolute pointing device which ++ * uses values of range 0-32767 for both axes, reports five button ++ * states (left, right, middle, side, extra) and two wheel states ++ * (vertical, horizontal; both relative) ++ */ ++#define VBOX_MAX 32767 ++ ++static int M_vbox (Gpm_Event * state, unsigned char *data) ++{ ++ struct input_event thisevent; ++ (void) memcpy (&thisevent, data, sizeof (struct input_event)); ++ ++ state->dx = state->dy = 0; ++ state->wdx = state->wdy = 0; ++ ++ // Pointer ++ if (thisevent.type == EV_ABS) { ++ if (thisevent.code == REL_X) { ++ state->x = thisevent.value * (win.ws_col+1) / VBOX_MAX; ++ realposx = thisevent.value * REALPOS_MAX / VBOX_MAX; ++ } else if (thisevent.code == REL_Y) { ++ state->y = thisevent.value * (win.ws_row+1) / VBOX_MAX; ++ realposy = thisevent.value * REALPOS_MAX / VBOX_MAX; ++ } ++ ++ // Wheels ++ } else if (thisevent.type == EV_REL) { ++ if (thisevent.code == REL_WHEEL) { ++ //state->buttons ^= thisevent.value > 0 ?
