Goal for this part
Filter the listing as you type.
Treat 10-Filter-Names as the source of truth for this checkpoint. If your local tree drifted, re-clone that folder rather than mixing files from neighbors.
What you should already know
You do not need prior GTK experience for part 1. Later parts assume you finished the earlier snapshots on the same machine.
- You can open a terminal and run
python3 - You are comfortable editing a
.pyfile and saving it - You have a desktop session (not a headless SSH box without display forwarding)
Why GTK fits Pathwalk
GTK powers many Linux file managers. Teaching Pathwalk means directories, selection, and safe delete—not reinventing the kernel.
Places sidebar + file list is the familiar two-pane pattern. Use pathlib for traversal and confirm before destructive ops.
After you run the snapshot, you should recognize the behavior described in the goal—before you move on. If the window (or server) never appears, stop and fix the run steps.
Code shape
Snapshots stay small on purpose. Look for this kind of core call as you read the folder:
for p in Path(folder).iterdir(): ...How to run it
Clone the teaching repo, open 10-Filter-Names, install what the README asks for, then run python3 app.py.
git clone https://github.com/michaeldunga1/fcc-gtk-files.git
cd fcc-gtk-files/10-Filter-Names
python3 -m venv .venv
source .venv/bin/activate
pip install -r ../requirements.txt
python3 app.pyCommon mistakes
- Ignoring platform-specific install notes in the snapshot README
- Case-sensitive filters that surprise users
- Filtering the wrong collection (all rows vs current folder)
- Clearing the query box without restoring the full list
