使用CGEventCreateMouseEvent()执行双击

Question

我正在使用以下代码来模拟鼠标的单击:

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

void LeftClick(const CGPoint point) 
{
 PostMouseEvent(kCGMouseButtonLeft, kCGEventMouseMoved, point);
 NSLog(@"Click!");
 PostMouseEvent(kCGMouseButtonLeft, kCGEventLeftMouseDown, point);
 PostMouseEvent(kCGMouseButtonLeft, kCGEventLeftMouseUp, point);
}

我可以使用基本相同的代码来进行控制点击(右键单击),方法是:

kCGEventLeftMouseDown

kCGEventLeftMouseUp

kCGMouseButtonLeft

他们各自的"正确"事件.该函数看起来像:

void RightClick(const CGPoint point) 
{
 PostMouseEvent(kCGMouseButtonRight, kCGEventMouseMoved, point);
 NSLog(@"Click Right");
 PostMouseEvent(kCGMouseButtonRight, kCGEventRightMouseDown, point);
 PostMouseEvent(kCGMouseButtonRight, kCGEventRightMouseUp, point);
}

但是,双击怎么样？我尝试发送2个leftclicks并连续两次调用PostMouseEvent()但没有运气.你如何进行双击？

谢谢!

Answer 1

看看CGEventSetIntegerValueField(event, kCGMouseEventClickState, clickCount).此外,即使将clickCount设置为2,在某些情况下,对于旧版应用,您可能还必须执行2个事件.

所以基本上:

1. 创建活动
2. 将点击次数设为2
3. 将事件类型设置为mousedown并发送
4. 将事件类型设置为mouseup并发送
5. 重复3和4

编辑:

void doubleClick(int clickCount) {
    CGEventRef theEvent = CGEventCreateMouseEvent(NULL, kCGEventLeftMouseDown, point, kCGMouseButtonLeft);  
    CGEventSetIntegerValueField(theEvent, kCGMouseEventClickState, clickCount);  
    CGEventPost(kCGHIDEventTap, theEvent);  
    CGEventSetType(theEvent, kCGEventLeftMouseUp);  
    CGEventPost(kCGHIDEventTap, theEvent);  
    CGEventSetType(theEvent, kCGEventLeftMouseDown);  
    CGEventPost(kCGHIDEventTap, theEvent);  
    CGEventSetType(theEvent, kCGEventLeftMouseUp); 
    CGEventPost(kCGHIDEventTap, theEvent); 
    CFRelease(theEvent); 
}

Answer 2

这是模拟双击的示例代码。

CGEventRef theEvent = CGEventCreateMouseEvent(NULL, kCGEventLeftMouseDown, CGPointMake(x, y), kCGMouseButtonLeft);  
CGEventPost(kCGHIDEventTap, theEvent);  
CGEventSetType(theEvent, kCGEventLeftMouseUp);  
CGEventPost(kCGHIDEventTap, theEvent);  

CGEventSetIntegerValueField(theEvent, kCGMouseEventClickState, 2);

CGEventSetType(theEvent, kCGEventLeftMouseDown);  
CGEventPost(kCGHIDEventTap, theEvent);  

CGEventSetType(theEvent, kCGEventLeftMouseUp); 
CGEventPost(kCGHIDEventTap, theEvent); 

CFRelease(theEvent); 

请注意，这CGEventSetIntegerValueField(theEvent, kCGMouseEventClickState, 2);是在第一组向下、向上点击之后发生的。
