objective-c - setIgnoresMouseEvents :YES not working (e. g。闪烁窗口)

Question

我认为我的问题最好在视频中描述:http://cl.ly/5Iou

基本上，我在窗口中创建一个跟踪区域，如下所示:

NSTrackingArea *area = [[NSTrackingArea alloc] initWithRect:[self frame] options:NSTrackingMouseEnteredAndExited | NSTrackingActiveAlways owner:self userInfo:nil];
[self addTrackingArea:area];
[area release];

然后我实现了:

-(void)mouseEntered:(NSEvent *)event {
    [self toggleDetail];
}
-(void)mouseExited:(NSEvent *)event {
    [self toggleDetail];
}

在 awakeFromNib 中，我输入了以下内容:

[attachedWindow setIgnoresMouseEvents:YES];

toggleDetail 看起来有点类似于:(弹出窗口是一个 MAAttachedWindow)

- (void)toggleDetail {
    if (!attachedWindow) {
        NSPoint buttonPoint = NSMakePoint(NSMidX([conditionImage frame]),
                                          NSMidY([conditionImage frame]));
        attachedWindow = [[MAAttachedWindow alloc] initWithView:view 
                                                attachedToPoint:buttonPoint 
                                                       inWindow:[self window] 
                                                         onSide:12
                                                     atDistance:65.0];
        //irrelevant window setup here
        [[self window] addChildWindow:attachedWindow ordered:NSWindowAbove];
    } 
    else {
        [[self window] removeChildWindow:attachedWindow];
        [attachedWindow orderOut:self];
        [attachedWindow release];
        attachedWindow = nil;
    }
}

因此，正如您在视频中看到的那样，如果我将鼠标移到窗口上远离窗口，然后将其移到弹出窗口上，则不会发生“脉冲”。但是，如果我将鼠标移到弹出窗口将出现的大致区域，然后将鼠标移到窗口中，它就会发出脉冲。看起来窗口几乎没有时间注册它不应该接收鼠标事件。有任何想法吗？我已经无计可施，试图解决这个问题。

哇，这很简单。我刚刚想通了。我调用这个:

[attachedWindow setIgnoresMouseEvents:YES];

在窗口初始化之前。因此，由于某种原因，它没有注册。所以，我把它移到这里:

//in toggleDetail
attachedWindow = [[MAAttachedWindow alloc] initWithView:view 
                                            attachedToPoint:buttonPoint 
                                                   inWindow:[self window] 
                                                     onSide:12
                                                 atDistance:65.0];
[attachedWindow setIgnoresMouseEvents:YES]; //HERE it works!
[[self window] addChildWindow:attachedWindow ordered:NSWindowAbove];

所以，就在它初始化之后、显示之前。终于可以工作了! :)
