[fpc-pascal] Directory Tree

[James Richters]

It looks like Lazarus is going to be the best way.   I've been looking at TTreeView... but I'm not sure I can make it do what I want.   I need to select multiple items in the tree at the same time, and then get a list of what has been selected.  Is there a way to add checkboxes to the tree with TTreeView?   Or is there a better tree object I should look at?

I am also wondering if there is some convenient method of saving a tree to some kind of data file, and later restoring the data file to the tree.  It seems that since trees are all over the place that maybe there is already a built in way to load a data file that somehow designates the hierarchical order.

I'm developing a new application where the user will need to select items from a tree structure.. I'm trying to figure out how to do the tree at all,  and allow the user to select multiple files and/or folders.   If the tree is going to be too complicated in text mode, then maybe I'll have to figure out Lazarus and go that way.  I haven't even started the project yet, but this tree selection with the ability to expand or collapse branches is going to be a big part of it, so I'm trying to see what's available.

As far as I understand, you are searching for a general tree component like TTreeView in Lazarus, but for FreeVision, running in text mode in console ?
