| Tab | What's there |
|---|---|
| Defaults | Default save location, default form width / height |
| Workspace | Grid style, color picker swatch, spacing px |
| Editor | Editor command for Event Handlers — Auto / VS Code / Notepad++ / IDLE / Custom |
| Autosave | Interval (minutes), enable/disable, autosave folder |
| Notifications | Reset dismissed warnings |
| Appearance | Theme dropdown — Light / Dark / System (planned) |
Picks which editor opens when you double-click a handler, hit F7, or follow any Open in editor entry.
| Preset | Behavior |
|---|---|
| Auto | Tries VS Code → Notepad++ → IDLE in order |
| VS Code | Opens project folder + jumps to the line |
| Notepad++ | Lightweight fallback |
| IDLE | Always works — runs python -m idlelib
|
| Custom | Free-form command with {file}, {line}, {folder}, {python} placeholders |
The dropdown auto-flips to Custom if you hand-edit the command. VS Code is the recommended pick — a CTkMaker VS Code extension is on the roadmap.
