I'm working on a new application which has a feature that allows the user to create arbitrary lists of items in a hierarchical fashion. Every item is by default a container, as there's no predefined "end point." The same interface should used to select an item as it is to create one. In other words, the user brings up the window and is presented with the base level, he can then either select one of those, create a new base level item, or navigate to the next level from one of those items, select something there, create a new item, or continue moving down. This repeats endlessly (actually, I doubt anyone will use more than three levels, but I don't intend on putting in a limitation.
As an example, let's say that I'm defining locations... column one would be a nation, column two a state or province, column three a city, etc.
I'm torn between using the column view (which would be great for selection and navigation, but less ideal for creation) and a simple list view, which would be handy for creation, less so for navigation. On Apple's website, I ran across this little note:
▪ Text editing works only in list view; don’t plan to make text editing available in column view.
Now, this is contrary to how the Finder works (go to column view, create a folder, and you can indeed edit the name) but I'll assume that there will be no functionality for editing text in column view.
I'm sure that there are examples out there which do this sort of thing, but I haven't come across them.
Any thoughts? Thanks!
I found that there does not appear to be too many people on this list using the data browser because a few questions have been asked regarding data browsers with very little response.
I use a simple Column view with no items that are containers so I'm not much help in that area. I do allow the editing of names in column view so I'm not sure what that note refers to.
I did a search of kDataBrowserNoItem in the Sample Apps and came up with 3 sample code projects that use DataBrowsers:
BasicDataBrowser (this is the one I used for my information), GrabBag and EmbededAppleScripts.
It's likely you already know about these but you didn't mention any. The BasicDataBrowser does use containers so that may help.
