如何知道NSWindow是否是Mac OS X Lion中的全屏？ [英] How to know if a NSWindow is fullscreen in Mac OS X Lion?

问题描述

我想我应该检查 [NSApplication presentationOptions] 是否包含 NSFullScreenModeApplicationPresentationOptions ，但是如何实现？ / p>

编辑：使用 [NSApplication presentationOptions] 无法在我的基于文档的应用程序中，在全屏和其他人不。我现在正在寻找另一个解决方案。我想知道为什么没有属性 [NSWindow isFullscreen] 或类似的东西。

解决方案

我只是寻找一个解决方案自己和基于Matthieu的回答我创建了一个类别在NSWindow，对我来说很好。

  @interface NSWindow（FullScreen）
 
  - （BOOL）mn_isFullScreen; 
 
 @end 
 
 @implementation NSWindow（FullScreen）
 
  - （BOOL）mn_isFullScreen 
 {
 return self styleMask]& NSFullScreenWindowMask）== NSFullScreenWindowMask）; 
} 
 
 @end 
  

I guess I should check if [NSApplication presentationOptions] contains NSFullScreenModeApplicationPresentationOptions, but how do I achieve that?

EDIT: using [NSApplication presentationOptions] doesn't work as in my document-based app there might be some documents in fullscreen and others not. I'm now looking for another solution. I'm wondering why there isn't a property called [NSWindow isFullscreen] or something like that.

解决方案

I was just looking for a solution myself and based on Matthieu's answer I created a category on NSWindow that works fine for me.

@interface NSWindow (FullScreen)

- (BOOL)mn_isFullScreen;

@end

@implementation NSWindow (FullScreen)

- (BOOL)mn_isFullScreen
{
    return (([self styleMask] & NSFullScreenWindowMask) == NSFullScreenWindowMask);
}

@end
