Question

当用户点击某个键盘键（CapsLock）时，我以编程方式生成鼠标单击。因此，当CapsLock打开时我向左鼠标按下，然后在CapsLock关闭时向左鼠标向上。

这行为正确，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，窗口正确移动。即我正确地“拖动”窗口，就像我在移动鼠标时按住鼠标左键一样。

然而，有一个问题 - 当我移动鼠标时窗口不移动，它仅在我第二次点击CapsLock后移动到最终位置。即在我'释放'鼠标按钮之后。

我需要做些什么才能确保在鼠标移动过程中刷新屏幕？

有趣的是，我也迷上了

[NSEvent addGlobalMonitorForEventsMatchingMask：NSLeftMouseDraggedMask

发现我的NSLog语句只在之后输出我发布了鼠标左键（真正的鼠标左键）

鼠标点击代码如下，我可以在必要时发布所有代码，但没有多少代码..

// 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);

如果您希望能够拖动窗口，问题是您还需要发布LeftMouseDragged事件。

只需致电beginEventMonitoring即可开始侦听大写锁定键事件和鼠标移动事件。事件处理程序将按照您的需要模拟鼠标左键和移动。这是我的博客的链接，您可以在其中下载Xcode 4的完整工作示例：http://www.jakepetroules.com/2011/06/25/simulating-mouse-events-in-cocoa

该示例位于公共领域，随心所欲地做任何事情。：）

根据Apple（NSEvent documentation），需要在“系统偏好设置”＆gt;中检查“启用辅助设备的访问权限”。通用访问为此工作，但我没有检查它，这不是一个问题。只是一个抬头。

如果您有任何其他问题，请告诉我，我会尽力帮助您。

// 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);
}

可可 - CGEventPost鼠标点击后屏幕没有刷新
