I want to simulate multi-touch event on jailbroken device, I tried the GSEvent, I couldn't known each field of the structs, so I just assumed each pathInfo meant one finger info, but no effect, could anyone give me some help?Thank you very much.
typedef struct touch {
int identity;
int x;
int y;
GSHandInfoType type;
} touch;
static void sendTouches(touch touches[])
{
if (touches_count<1) {
return;
}
uint8_t touchEvent[sizeof(GSEventRecord) + sizeof(GSHandInfo) + sizeof(GSPathInfo)*touches_count];
// structure of touch GSEvent
struct GSTouchEvent {
GSEventRecord record;
GSHandInfo handInfo;
} * event = (struct GSTouchEvent*) &touchEvent;
bzero(touchEvent, sizeof(touchEvent));
// set up GSEvent
event->record.type = kGSEventHand;
event->record.subtype = kGSEventSubTypeUnknown;
event->record.windowLocation = CGPointMake(touches[0].x, touches[0].y);
event->record.timestamp = GSCurrentEventTimestamp();
event->record.infoSize = sizeof(GSHandInfo) + sizeof(GSPathInfo);
event->handInfo.type = touches[0].type;
event->handInfo.x52 = touches_count;
event->handInfo.pathInfosCount = touches_count;
for (int i=0; i<touches_count; i++) {
bzero(&event->handInfo.pathInfos[i], sizeof(GSPathInfo));
event->handInfo.pathInfos[i].pathIndex = 1;
event->handInfo.pathInfos[i].pathIdentity = 2;
event->handInfo.pathInfos[i].pathProximity = (touches[i].x == kGSHandInfoTypeTouchDown || touches[i].x == kGSHandInfoTypeTouchDragged || touches[i].x == kGSHandInfoTypeTouchMoved) ? 0x03 : 0x00;;
event->handInfo.pathInfos[i].pathLocation = CGPointMake(touches[i].x, touches[i].y);
}
mach_port_t port = (mach_port_t)getFrontMostAppPort();
GSSendEvent((GSEventRecord *)event, port);
}
int test()
{
// simulate two fingers touch from the center to two sides of the screen.
struct touch touchesDown[2] = [{0, 140, 200, kGSHandInfoTypeTouchDown},
{1, 160, 200, kGSHandInfoTypeTouchDown}];
struct touch touchesMove[2] = [{0, 40, 200, kGSHandInfoTypeTouchDragged},
{1, 300, 200, kGSHandInfoTypeTouchDragged}];
struct touch touchesUp[2] = [{0, 40, 200, kGSHandInfoTypeTouchUp},
{1, 300, 200, kGSHandInfoTypeTouchUp}];
sendTouches(touchesDown);
usleep(20000);
sendTouches(touchesMove);
usleep(20000);
sendTouches(touchesUp);
