我正在尝试将keynav移植到OS X.它基本上正在工作,但由于无法更改(全局)受监控事件,我遇到了问题。
是否可以在鼠标单击事件期间禁止键盘修改器?也许使用序列,例如用“控制键启动”+鼠标点击创建键盘事件?
这是我的鼠标点击方法:
- (void)clickMouseAtPoint:(CGPoint)point
{
CGEventRef move = CGEventCreateMouseEvent(
NULL, kCGEventMouseMoved,
point,
kCGMouseButtonLeft // ignored
);
CGEventRef click1_down = CGEventCreateMouseEvent(
NULL, kCGEventLeftMouseDown,
point,
kCGMouseButtonLeft
);
CGEventRef click1_up = CGEventCreateMouseEvent(
NULL, kCGEventLeftMouseUp,
point,
kCGMouseButtonLeft
);
CGEventPost(kCGHIDEventTap, move);
CGEventPost(kCGHIDEventTap, click1_down);
CGEventPost(kCGHIDEventTap, click1_up);
CFRelease(click1_up);
CFRelease(click1_down);
CFRelease(move1);
}
答案 0 :(得分:0)
所以这就是我最终的结果。特别是在这里做的背景:当按下ctrl +逗号时,keynav被覆盖到整个桌面,用户可以使用按住ctrl + SomeKeys来导航十字准线,并通过a模拟鼠标点击交叉的位置。第二个ctrl +逗号(在下面的代码片段中等待第二次单击时设置awaitClick)。
现在,在单击完成之前,控制键修饰符将从键盘事件中删除。此外,当显示keynav时,所有键盘输入都与键码-1交换。我通过试验证明了这一点,这抑制了按键。
如果这是一个好方法,我不能说。但到目前为止它可靠地运作。
CGEventRef
myCGEventCallback(CGEventTapProxy proxy, CGEventType type,
CGEventRef event, void *refcon)
{
if ((type != kCGEventKeyDown) && (type != kCGEventKeyUp))
return event;
CGKeyCode keycode = (CGKeyCode)CGEventGetIntegerValueField(event, kCGKeyboardEventKeycode);
EWAppDelegate *appInstance = [NSApplication sharedApplication].delegate;
CGEventFlags flags = CGEventGetFlags(event);
if (_awaitClick && keycode == (CGKeyCode)43 && type == kCGEventKeyDown)
{
flags = flags & ~kCGEventFlagMaskControl;
CGEventSetFlags(event, flags);
NSLog(@"suppressed control key");
}
BOOL didHandle = NO;
if (type == kCGEventKeyDown)
{
didHandle = [appInstance handleNavKey:keycode flags:flags];
}
NSLog(@"pressed keycode %d", keycode);
if (didHandle || _navIsSHowing) {
CGEventSetIntegerValueField(event, kCGKeyboardEventKeycode, (int64_t)-1);
NSLog(@"nav");
}
return event;
}
- (BOOL)registerGlobalKeyBoardModifier
{
CFMachPortRef eventTap;
CGEventMask eventMask;
CFRunLoopSourceRef runLoopSource;
eventMask = ((1 << kCGEventKeyDown) | (1 << kCGEventKeyUp));
eventTap = CGEventTapCreate(kCGSessionEventTap, kCGHeadInsertEventTap, 0,
eventMask, myCGEventCallback, NULL);
if (!eventTap) {
fprintf(stderr, "failed to create event tap\n");
return NO;
}
runLoopSource = CFMachPortCreateRunLoopSource(
kCFAllocatorDefault, eventTap, 0);
CFRunLoopAddSource(CFRunLoopGetCurrent(), runLoopSource,
kCFRunLoopCommonModes);
CGEventTapEnable(eventTap, true);
return YES;
}
