如何以编程方式(无需使用鼠标)触发mouseDown:(NSEvent *)?

问题描述

我正在开发一个Leap Motion应用程序，已经在其中移动了光标，但是我不知道如何以编程方式触发mouseDown:(NSEvent *).

I am developing a Leap Motion Application where I already move the cursor with it, but I don't know how I can trigger a mouseDown:(NSEvent *) programmatically.

推荐答案

这对我 在可可Mac中很有效 :

This worked well for me in Cocoa Mac:

void PostMouseEvent(CGMouseButton button, CGEventType type, const CGPoint point)
{
   CGEventRef theEvent = CGEventCreateMouseEvent(NULL, type, point, button);
   CGEventSetType(theEvent, type);
   CGEventPost(kCGHIDEventTap, theEvent);
   CFRelease(theEvent);
}

例如，要在我使用的点(500,500)处触发MouseDown事件:

For example, to trigger a MouseDown event at the point (500,500) I've used:

PostMouseEvent(kCGMouseButtonLeft, NX_LMOUSEDOWN, CGPointMake(200, 200));
