如何在NSTabView中更改选项卡按钮和视图本身的颜色? [英] How to change the color of the tab button and the view itself in NSTabView?

问题描述

我正在使用OS X应用程序，并且正在使用NSTabView.我想更改标签(按钮)的背景颜色.当前背景为蓝色，(属性检查器->外观=继承(浅绿色).

I am working on OS X app, and I am using NSTabView. I would like to change the background color of the tab (button). Currently the background is blue, (Attribute Inspector -> Appearance = Inherited (Aqua).

视图本身的背景色也是如此.我将NSTabView子类化，然后在此代码中添加以下内容:

Same is true with the background color of the view itself. I subclass the NSTabView, and I add inside this code:

 CGContextRef context = (CGContextRef) [[NSGraphicsContext currentContext] graphicsPort];
 CGContextSetRGBFillColor(context, 241.0/255.0, 252.0/255.0, 255.0/255.0, 1.0);
 CGContextFillRect(context, NSRectToCGRect(dirtyRect));

这确实会更改背景颜色，但还会用背景颜色覆盖选项卡...

which does change the background color, but also cover the tabs with the background color...

对NSTabView自定义的任何帮助将深表感谢.

Any help with customization of the NSTabView will be deeply appreciated.

推荐答案

几个小时后，我认为您无法使用NSTabView完成它. 该文档说您不能再这样做了，NSTabView会尊重操作系统选择的主题.

After a couple of hours, I think you can't do it with NSTabView. The documentation says you can no longer do it and NSTabView will respect the theme chosen by the OS instead.

这使我想到了如何绘制自己的NSTabView标签?，我相信您已经看到了.但是，尽管有文档说明，SetImage/ForSegment对我却不起作用.

This led me to How to draw your own NSTabView tabs?, which I'm sure you've seen. But despite the documentation, SetImage/ForSegment did not work for me.

[ NSSegmentedControl颜色似乎找到了一种解决方案，并且SMSegmentView 是另一个.这两种解决方案都是较新的.

[NSSegmentedControl Colors seems to have found one solution, and SMSegmentView is another, although there may be licensing issues. Both these solutions are more recent.

我希望以上内容对您有帮助，祝您好运.

I hope the above will prove useful to you and good luck.
