I just want to select just one item in this window, but how to deal the bTag? Is there any other method to do this?
bTag = GUILayout.Toggle(bTag, info.Name);
Hey, AngryAnt! I have seen your article, it is very helpful! But I want make a tree view, I think it need recursion。
I build a simple browse demo! It takes me all day!

Nicely done Francis! Would make an awesome addition to the Wiki (hint 
).
I will, before that I have to fixed some bugs! 
I dont know how to edit the wiki, so paste the code in here:

Excellent, thanks for sharing Francis!
I gave it a try but since my C# skills are a bit limited I’m not able to find how you did the “…” move up the folder tree function in your stand-alone. Perhaps these warnings are related to this functionality?
I’m talking about the “…” like this:
hey, bigkahuna, I made two type of browser as u see, I dont konw how to add parent button(…) and use recursion. Anyway, I paste the code of parent button(…) in here:
//show the up on level button, if click this button the direcotory will up to its parent
GUILayout.BeginHorizontal();
GUILayout.Label(dirTexture, dirStyle, GUILayout.Width(12));
if( path != "/" GUILayout.Button("..", dirStyle))
{
directoryInfo = directoryInfo.Parent;
path = directoryInfo.FullName;
}
GUILayout.EndHorizontal();
Thanks Francis, but I’m afraid I don’t understand. Could you upload a package file? If not, that’s OK. I’ll try to figure it out later when I have some free time.
Not to be digging around too much here, but I just found this and couldn’t resist clarifying for you BigKahuna.
What he means is that he knows how to select the Unix navigation items, but once they’re selected he doesn’t know how to use them to modify the path properly.
I added his code in at line 92, and it added the … nav item. Which is all well and good, but it doesn’t do anything
@Francis: What you need to do is if the … item is selected, use some string functions to remove part of the path up to the previous “/”, then update the browser to that path. I would do it, but I don’t know any C# (and don’t intend on learning it unless I really have to).
Hope that makes some sense!
