Question

我在这里的法典把 mo局限于屏幕上的一个区域,它的工作相对较好,只有一个大问题。潮use在沿区域边缘移动时,会得到清洁/友好的移动,而是以非常巧妙的方式跳出,我认为这可能是由于CGWarpMouseCursorPosition造成每个“战争”。

www.un.org/Depts/DGACM/index_spanish.htm 任何人都能够说,这是否在我的法典中引起这种拖延,或者事实上是 mo忙的。如果是摩擦功能的话,我是否能够顺利地搬迁 mo? 我在闪电中做了同样的事情,而且它无休止地运作,我知道, lo子仅仅花了这么多时间执行,它减缓了事情,因为它只剩下4或5次。

CGEventRef 
mouse_filter(CGEventTapProxy proxy, CGEventType type, CGEventRef event, void *refcon) {


    CGPoint point = CGEventGetLocation(event);

    float tX = point.x;
    float tY = point.y;

    if( tX <= 700 && tX >= 500 && tY <= 800 && tY >= 200){
        // target is inside O.K. area, do nothing
    }else{

    CGPoint target; 

    //point inside restricted region:
    float iX = 600; // inside x
    float iY = 500; // inside y

    // delta to midpoint between iX,iY and tX,tY
    float dX;
    float dY;

    float accuracy = .5; //accuracy to loop until reached

    do {
        dX = (tX-iX)/2;
        dY = (tY-iY)/2;

        if((tX-dX) <= 700 && (tX-dX) >= 500 && (tY-dY) <= 800 && (tY-dY) >= 200){
            iX += dX;
            iY += dY;
        } else {
            tX -= dX;
            tY -= dY;
        }

    } while (abs(dX)>accuracy || abs(dY)>accuracy);

        target = CGPointMake(roundf(tX), roundf(tY));
        CGWarpMouseCursorPosition(target);

    }



    return event;
}

int
main(int argc, char *argv[]) {
    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
    CFRunLoopSourceRef runLoopSource;
    CGEventMask event_mask;
    event_mask = CGEventMaskBit(kCGEventMouseMoved) | CGEventMaskBit(kCGEventLeftMouseDragged) | CGEventMaskBit(kCGEventRightMouseDragged) | CGEventMaskBit(kCGEventOtherMouseDragged);

    CFMachPortRef eventTap = CGEventTapCreate(kCGHIDEventTap, kCGHeadInsertEventTap, 0, event_mask, mouse_filter, NULL);

    if (!eventTap) {
        NSLog(@"Couldn t create event tap!");
        exit(1);
    }

    runLoopSource = CFMachPortCreateRunLoopSource(kCFAllocatorDefault, eventTap, 0);

    CFRunLoopAddSource(CFRunLoopGetCurrent(), runLoopSource, kCFRunLoopCommonModes);

    CGEventTapEnable(eventTap, true);

    CFRunLoopRun();

    CFRelease(eventTap);
    CFRelease(runLoopSource);
    [pool release];

    exit(0);

Answer 1

As you discovered, CGSetLocalEventsSuppressionInterval fixes your problem.

However, it s deprecated as of 10.6. the Apple docs state:

This function is not recommended for general use because of undocumented special cases and undesirable side effects. The recommended replacement for this function is CGEventSourceSetLocalEventsSuppressionInterval, which allows the suppression interval to be adjusted for a specific event source, affecting only events posted using that event source.

遗憾的是,替换代码“CGEventSourceSet LocalEventsSuppressionInterval没有使用。

相反,在战争之后立即使用:

CGPoint warpPoint = CGPointMake(42, 42);
CGWarpMouseCursorPosition(warpPoint);
CGAssociateMouseAndMouseCursorPosition(true);

The documentation makes no mention of this behavior, but it appears to cancel the suppression interval after the warp.

Answer 2

I could get CGEventSourceSetLocalEventsSuppressionInterval to work with CGWarpMouseCursorPosition the following way:

auto eventSourceRef = CGEventSourceCreate(kCGEventSourceStateCombinedSessionState);
CGEventSourceSetLocalEventsSuppressionInterval(eventSourceRef, 0);

这项工程用进行。虽然对我没有帮助。

Answer 3

你或许会重新寻找CGSet LocalEventsSuppressionInterval(CGSet)这一方法,截至10.6年,它仍在10.7年运作。
