Declarative Tcl/Tk UI library for Python.
- Somewhat React-like (there is effectively a Tk VDOM).
- Well typed.
- Maps very closely to the underlying Tcl/Tk for ease of debugging.
- Zero dependency.
- On mac sometimes you have to start by wiggling the window.
- Small enough to understand how it works.
- In an incomplete state – much functionality missing.
After pip install tkintergalactic, just run:
, onbuttonrelease=inc_counter),
tk.Text(content=f"Button clicked {counter} times"),
),
).run()
None:
state.tasks.append(Task(state.new_task_description))
state.new_task_description = “”
state.tasks.append(Task(state.new_task_description))
state.new_task_description = “”
@tk.command()
def delete_task(i: int) -> None:
state.tasks.pop(i)
@tk.command()
def toggle_class_complete(i: int) -> None:
state.tasks[i].complete = not state.tasks[i].complete
@tk.command(with_event=True)
def set_new_task_description(e: tk.EventKeyRelease) -> None:
state.new_task_description = e.value
tk.Window(
title=”TODO List”,

app=lambda: tk.Frame(

Your repo link is probably not set to public.

Link gives a 404 :-(

Nice! (starred and forked so I'll be more inclined to try it)
What projects do you feel this would be esp. well-suited to?
(your doing a "To-do" app where a list would normally appear was a fun bit)
Are there projects which you feel this would absolutely _not_ work for? In particular, I have an itch to do a line/arc drawing program w/ a canvas…

why not just call it reactTK

Why declarative became synonym of nested hell? Can't you mimic an imperative flow of UI construction but under the hood have it declarative or whatever you want?
