使用 CGEventCreateMouseEvent() 执行双击

发布于 2024-08-06 03:25:56 字数 1095 浏览 10 评论 0原文

我使用以下代码来模拟鼠标单击:

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执行控制单击(右键单击),方法是将:

kCGEventLeftMouseDown

kCGEventLeftMouseUp

kCGMouseButtonLeft

更改为各自的“右键”事件。该函数看起来类似于:

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? 我尝试发送两次左键单击并连续两次调用 PostMouseEvent() 但没有成功。 如何执行双击?

谢谢!

I'm using the following code to simulate a click of the mouse:

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);
}

I can use basically the same code to do a control-click (right click) by changing:

kCGEventLeftMouseDown

kCGEventLeftMouseUp

kCGMouseButtonLeft

to their respective "Right" events. The function looks something like:

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

But, how about a double click?
I tried sending 2 leftclicks and calling PostMouseEvent() twice in a row but no luck.
How do you perform a double click?

thanks!

查看 CGEventSetIntegerValueField(event, kCGMouseEventClickState, clickCount)。此外,即使将 clickCount 设置为 2,在某些情况下,对于旧版应用程序,您可能也必须执行 2 个事件。

所以基本上:

  1. 创建事件
  2. 将点击计数设置为 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); 
}

Look into CGEventSetIntegerValueField(event, kCGMouseEventClickState, clickCount). Also, even after setting the clickCount to 2, you may have to perform 2 events in some cases, for legacy apps.

So basically:

  1. Create event
  2. Set click count to 2
  3. Set event type to mousedown and send
  4. Set event type to mouseup and send
  5. Repeat 3 and 4

Edit:

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); 
}

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,CGEventSetIntegerValueField(theEvent, kCGMouseEventClickState, 2); 在第一组向下、向上点击之后执行。

This is sample code to simulate a double click.

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); 

Notice that CGEventSetIntegerValueField(theEvent, kCGMouseEventClickState, 2);goes after the first set of down,up clicks.
