可可窗口 - 如何定位在右上角

Question

我需要将我的NSWindow放置在屏幕的右上方,就在菜单栏下方(如通知).这样做的最佳方法是什么？

您可以使用以下方法将窗口位置设置为右上角:

- (void)setWindowPosition
{
    NSPoint pos;
   pos.x = [[NSScreen mainScreen] visibleFrame].origin.x + [[NSScreen mainScreen] visibleFrame].size.width - [_window frame].size.width ;
    pos.y = [[NSScreen mainScreen] visibleFrame].origin.y + [[NSScreen mainScreen] visibleFrame].size.height - [_window frame].size.height  ;
   [_window setFrameOrigin : pos];
}

在您的调用此方法applicationDidFinishLaunching:,并注册 windowDidResizeNotification处理resize事件为:

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
    [self setWindowPosition];   //set window pos

   [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleNotification:) name:NSWindowDidResizeNotification object:nil];    //register resize notification

}

现在在您的通知处理程序方法中,再次更新窗口位置.

- (void)handleNotification: (id) sender
{
     [self setWindowPosition];
}
