Please give me some hints about triangle disclosure

dear all

i am new to applescript development and want to construct a project with triangle disclosure to show files and directories of the file system.

For example, please take a look at this png file. http://sky.csie.org/browser.png

Please give me some hints or samples to fulfill the requirement.

Thanks a lot in advance.

I know this question is kind of old, but since the link still works I thought I’d recommend you looking into Outline View in IB. It should do what you’re looking for.

There is an example of how to work with it called “Simple Outline” in the examples folder.
