纹理的NSWindow与setBackgroundColor有一个带有灰色背景 [英] Textured NSWindow with setBackgroundColor has a tinged grey background

问题描述

基本上我想做一个简单的窗口，有一个统一的标题栏和窗口（即纹理）和一个白色背景，如Xcode的窗口：

所以我有一个纹理的窗口在IB和我有它连接到我的应用程序代理通过绑定。然后我将这行代码添加到应用程序委托：

  [about setBackgroundColor：[NSColor whiteColor]]; 
 

虽然对于其他颜色，如红色和蓝色，窗口似乎更改颜色，但每当我使用[ NSColor whiteColor]这个窗口看起来没有什么附近像Xcode的窗口一样耀眼明亮：




有趣的是，当窗口无效时，我最终得到Xcode的白色：


这是一个错误，还是应该看起来真的灰色？白色？

解决方案

我发现了一个教程，使用一个漂亮的ghetto hack来交换框架视图的drawRect： href =http://parmanoir.com/Custom_NSThemeFrame =nofollow noreferrer> http://parmanoir.com/Custom_NSThemeFrame

它不会'/ b>

最后的结果：

编辑：我提交了一个反馈助理报告，而在Yosemite DP 7或Xcode 6.1这个问题似乎是固定的。设置带纹理的窗口的背景颜色现在会生成无色的颜色。

Basically I want to make a simple about window that has a unified title bar and window (i.e textured) and a white background, like Xcode's about window:

So I have a textured window in IB and I have it connected to my app delegate via bindings. I then add this line of code to the app delegate:

[about setBackgroundColor:[NSColor whiteColor]];

Whilst for other colours like red and blue the window seems to change colour fine, but whenever I use [NSColor whiteColor] the window looks nowhere near as dazzlingly bright as Xcode's window:

Interestingly enough, when the window is inactive I end up getting Xcode's white colour:

Is this a bug? Or is it supposed to look really grey? How can I make this window "true white"?

解决方案

I found a tutorial that uses a pretty darn ghetto hack to swap the frame view's drawRect: method: http://parmanoir.com/Custom_NSThemeFrame

It doesn't even require you to subclass NSWindow, but I did it anyway in case I wanted to use it on another window or something.

The final result:

Edit: I submitted a feedback assistant report a while back, and as of either Yosemite DP 7 or Xcode 6.1 this issue seems to be fixed. Setting the background colour of a textured window now produces a non-tinged colour.
