我有一个小程序,当它从屏幕左边超过500像素时,应将鼠标移动到某一点(在本例中为100,100)。 CGEventTap正确接收kCGEventMouseMoved事件,但CGEventSetLocation似乎只移动诸如mouseUp之类的事件,而不是MouseMoved。
是否可以使用CGEventSetLocation移动鼠标?如果没有,还有其他方法吗?
我在这里包含了我的代码:
CGEventRef
mouse_filter(CGEventTapProxy proxy, CGEventType type, CGEventRef event, void *refcon) {
if (type != kCGEventMouseMoved)
return event;
CGPoint point = CGEventGetLocation(event);
CGPoint target = CGPointMake(500,point.y);
if (point.x >= 500){
CGEventSetLocation(event,target);
printf("(%f,%f)\n", point.x, point.y);
}
return event;
}
int
main(int argc, char *argv[]) {
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
CFRunLoopSourceRef runLoopSource;
CGEventMask event_mask;
event_mask = (1 << kCGEventMouseMoved);
CFMachPortRef eventTap = CGEventTapCreate(kCGSessionEventTap, kCGHeadInsertEventTap, 0, event_mask, mouse_filter, NULL);
if (!eventTap) {
NSLog(@"Couldn't create event tap!");
exit(1);
}
runLoopSource = CFMachPortCreateRunLoopSource(kCFAllocatorDefault, eventTap, 0);
CFRunLoopAddSource(CFRunLoopGetCurrent(), runLoopSource, kCFRunLoopCommonModes);
CGEventTapEnable(eventTap, true);
CFRunLoopRun();
CFRelease(eventTap);
CFRelease(runLoopSource);
[pool release];
exit(0);
}
答案 0 :(得分:0)
令人困惑的是,the function you want实际上不在Quartz Event Services中,而是Quartz Display Services。
