问题描述
我摔跤的 NSPathControl 。具体来说，我有一个对话框（由NIB生成），询问用户的标题和路径。该路径应该是用户硬盘驱动器上的本地路径。因此，在Xcode 4中，我在一个 NSPathControl 中拖动。在属性检查器中，我将其风格设置为弹出。
I'm wrestling with NSPathControl. Specifically, I have a dialog (generated by a NIB) which asks the user for a title and a path. The path is supposed to be a local path on the user's hard drive. So, in Xcode 4, I dragged in an NSPathControl. In the Attributes inspector, I set its style to "Pop Up".
这很像我期待的。如果我单击它，我得到一个菜单，其中包含与当前选择相关的一些公共路径或路径，以及一个选择...选项，打开一个对话框并允许路径选择。
This pretty much works like I expect. If I click it, I get a menu with a few common paths or paths related to the current selection, and a "Choose..." option which opens up a dialog box and allows a path selection.
问题是，它看起来不像Cocoa下拉列表，因为没有边框或按钮的东西。我如何使这个看起来更像一个 NSPopUpButton ，这可能是人们期望的。
The problem is, it doesn't look like a Cocoa dropdown, because there's no border or button stuff at all. How can I make this look more like an NSPopUpButton, which is presumably what someone would expect.
对Cocoa来说是新的，愿意被告知我要走这条路。如果我以错误的方式走，什么是一个更好的方式来让用户选择一个路径？
Alternatively, I'm new to Cocoa and willing to be told I'm going about this the wrong way. If I'm going about it the wrong way, what's a better way to go about having the user select a path?
这里是一个例子，我试图do：
Here's an example of what I'm trying to do:
查看路径下拉菜单？我希望它看起来像这样的一个...
See the path dropdown? I would have expected it to look like one of these...
...但是，我想写一个行为良好的Cocoa应用程序，所以我真正想要的是，什么是正确的方法这样做？提前感谢。
...but, that said, I'm trying to write a well-behaved Cocoa app, so what I really want is, "What's the right way to do this?" Thanks in advance.
推荐答案
我之前的做法是通过使用高度自定义的 NSPopUpButton 。我不知道一个更好的方法。
The way I've done this before is by recreating the control myself using a highly customized NSPopUpButton. I don't know of a better way. You should ask for one.
