Readme for brick-filetree-

[back to package description]


Hackage BSD3 license Stackage Lts StackageetreeNightly Build status

A brick widget for exploring file trees.

You can dig through my unfinished cli file browser Delve for a few examples if you like.

Note that this works relatively well, but I give no guarantees about future maintenance or feature requests.

Allows selecting multiple files/directories from anywhere in your filesystem which can be viewed from your brick app and used for whatever you like.

Note, this uses lazy IO to build the file tree, which will be run iteratively as you use the UI to explore it; this allows better performance, but all the usual lazyIO caveats apply; shouldn't cause you too much trouble though.


  • Create a FileTree using newFileTree
  • Store this FileTree in your Brick State somewhere
  • Render the FileTree using renderFileTree
  • Wire up handlers for brick events to trigger FileTree actions, e.g. moveUp, toggleFlagged, etc.
  • At some point you'll want to get the selected object with getCurrentFilePath or get all flagged items with getFlagged.

See Hackage for docs.
