cocoa-单击CGEventPost鼠标后屏幕不刷新

当用户单击某个键盘键（CapsLock）时，我通过编程生成鼠标单击。 当CapsLock打开时，我用鼠标左键按下，然后当CapsLock关闭时，用鼠标左键向上

例如，如果我将鼠标放在窗口标题栏上，单击CapsLock，然后移动鼠标，然后单击CapsLock，则窗口将正确移动。i、 e.我正确地“拖动”窗口，就好像我在移动鼠标时按下了鼠标左键一样

但是有一个问题-当我移动鼠标时窗口不移动，它只在我第二次单击CapsLock后移动到最终位置。i、 e.在我“释放”鼠标按钮后

我需要做什么来确保在鼠标移动期间刷新屏幕

有趣的是，我也迷上了

[N事件添加GlobalMonitorForeventsMatchingMask:NSLeftMouseDraggedMask

发现我的NSLog语句只有在我释放鼠标左键（真正的鼠标左键）后才输出

鼠标点击代码在下面，我可以发布所有的代码，如果需要的话，没有太多

// simulate mouse down

// get current mouse pos
CGEventRef ourEvent = CGEventCreate(NULL);
CGPoint point = CGEventGetLocation(ourEvent);
NSLog(@"Location? x= %f, y = %f", (float)point.x, (float)point.y);

CGEventSourceRef source = CGEventSourceCreate(kCGEventSourceStateCombinedSessionState);
CGEventRef theEvent = CGEventCreateMouseEvent(source, kCGEventLeftMouseDown, point, kCGMouseButtonLeft);
CGEventSetType(theEvent, kCGEventLeftMouseDown);
CGEventPost(kCGHIDEventTap, theEvent);
CFRelease(theEvent);


// simulate mouse up

// get current mouse pos
CGEventRef ourEvent = CGEventCreate(NULL);
CGPoint point = CGEventGetLocation(ourEvent);
NSLog(@"Location? x= %f, y = %f", (float)point.x, (float)point.y);

CGEventSourceRef source = CGEventSourceCreate(kCGEventSourceStateCombinedSessionState);
CGEventRef theEvent = CGEventCreateMouseEvent(source, kCGEventLeftMouseUp, point, kCGMouseButtonLeft);
CGEventSetType(theEvent, kCGEventLeftMouseUp);
CGEventPost(kCGHIDEventTap, theEvent);
CFRelease(theEvent);

如果希望能够拖动窗口，问题是还需要发布

LeftMouseDragged

事件

只需调用

beginEventMonitoring

即可开始侦听大写锁定键事件和鼠标移动事件。事件处理程序将根据需要模拟鼠标左键按下和移动。以下是我的博客链接，您可以在这里下载Xcode 4的完整工作示例：

该示例位于公共域中，请随意使用它。：）

根据Apple（），“启用辅助设备访问”需要在“系统首选项”>“通用访问”中进行检查，但我没有检查，这不是问题。只是提醒一下。

请让我知道，如果你有任何进一步的问题，我会尽力帮助

// Begin listening for caps lock key presses and mouse movements
- (void)beginEventMonitoring
{
    // Determines whether the caps lock key was initially down before we started listening for events
    wasCapsLockDown = CGEventSourceKeyState(kCGEventSourceStateHIDSystemState, kVK_CapsLock);

    capsLockEventMonitor = [NSEvent addGlobalMonitorForEventsMatchingMask:(NSFlagsChangedMask) handler: ^(NSEvent *event)
    {
        // Determines whether the caps lock key was pressed and posts a mouse down or mouse up event depending on its state
        bool isCapsLockDown = [event modifierFlags] & NSAlphaShiftKeyMask;
        if (isCapsLockDown && !wasCapsLockDown)
        {
            [self simulateMouseEvent: kCGEventLeftMouseDown];
            wasCapsLockDown = true;
        }
        else if (wasCapsLockDown)
        {
            [self simulateMouseEvent: kCGEventLeftMouseUp];
            wasCapsLockDown = false;
        }
    }];

    mouseMovementEventMonitor = [NSEvent addGlobalMonitorForEventsMatchingMask:(NSMouseMovedMask) handler:^(NSEvent *event)
    {
        [self simulateMouseEvent: kCGEventLeftMouseDragged];
    }];
}

// Cease listening for caps lock key presses and mouse movements
- (void)endEventMonitoring
{
    if (capsLockEventMonitor)
    {
        [NSEvent removeMonitor: capsLockEventMonitor];
        capsLockEventMonitor = nil;
    }

    if (mouseMovementEventMonitor)
    {
        [NSEvent removeMonitor: mouseMovementEventMonitor];
        mouseMovementEventMonitor = nil;
    }
}

-(void)simulateMouseEvent:(CGEventType)eventType
{
    // Get the current mouse position
    CGEventRef ourEvent = CGEventCreate(NULL);
    CGPoint mouseLocation = CGEventGetLocation(ourEvent);

    // Create and post the event
    CGEventRef event = CGEventCreateMouseEvent(CGEventSourceCreate(kCGEventSourceStateHIDSystemState), eventType, mouseLocation, kCGMouseButtonLeft);
    CGEventPost(kCGHIDEventTap, event);
    CFRelease(event);
}

您是如何为left caps lock key检索密钥事件的？它的事件循环在哪里？没问题，很高兴能提供帮助。：）也为我的示例代码库添加了一点新的内容！
