Textual Application-Adding Functionality ?
I am trying to create a define function that would show up in one of the placeholders in the TUI. How would I do that ?
I am sing the incredible Textual Library by @Will McGugan
My Code :
from textual.app import App
from textual.reactive import Reactive
from textual.widgets import Footer, Placeholder
class SmoothApp(App):
"""Demonstrates smooth animation. Press 'b' to see it in action."""
async def on_load(self) -> None:
"""Bind keys here."""
await self.bind("b", "toggle_sidebar", "Toggle sidebar")
await self.bind("q", "quit", "Quit")
show_bar = Reactive(False)
def watch_show_bar(self, show_bar: bool) -> None:
"""Called when show_bar changes."""
self.bar.animate("layout_offset_x", 0 if show_bar else -40)
def action_toggle_sidebar(self) -> None:
"""Called when user hits 'b' key."""
self.show_bar = not self.show_bar
async def on_mount(self) -> None:
"""Build layout here."""
footer = Footer()
self.bar = Placeholder(name="left")
await self.view.dock(footer, edge="bottom")
await self.view.dock(Placeholder(), Placeholder(), edge="top")
await self.view.dock(self.bar, edge="left", size=40, z=1)
self.bar.layout_offset_x = -40
# self.set_timer(10, lambda: self.action("quit"))
SmoothApp.run(log="textual.log", log_verbosity=2)
