自定义NSPathControl [英] Customise NSPathControl

问题描述

我想做一个自定义的NSPathControl. NSPathCell具有方法+ pathComponentCellClass，您可以在其中返回组件单元格的自定义类. 我有一个NSPathComponentCell子类，我在那儿返回了它，但是它不起作用. 该方法不会被调用.为什么?

I would like to make a custom NSPathControl. NSPathCell has the method + pathComponentCellClass, where you can return the custom class of the component cells. I have a NSPathComponentCell subclass, which I return right there, but it doesn't work. The method does not get called. Why?

在文档说:

子类可以重写此方法以返回自动使用的自定义单元格类.默认情况下，该方法返回[NSPathComponentCell class]或其专门的子类.

Subclasses can override this method to return a custom cell class that is automatically used. By default, the method returns [NSPathComponentCell class], or a specialized subclass thereof.

如果这是错误的，还有另一种自定义NSPathControl的方法吗?

If this is wrong, is there another way to customise NSPathControl?

推荐答案

我找到了解决方案并将其发布在 github . 我从NSPathControl继承了子类.其实很简单.

I found the solution and posted it on github. I subclassed from NSPathControl. It's pretty simple actually.
