• textual

  • reactive

    • descriptor protocol ->
      • auto refreshing
      • var() from textual.reactive wont causes refreshes
      • built in validates_
      • built in watch_
        • check watch01.py for example

  • dev tools

    • super useful
      • allows for double consoles (textual console)
      • from textual import log or TextualHandler with logger()

  • workers

    • on_worker_state_changed
    • – dev shows the lifetime of workers
    • can you decorates for workers as well to auto generate them

  • uses id to handle conditions of apps

  • widgets

    • mini apps responsible for an area of the screen
    • loading indicator
      • replaces wigets for a loading icon when generating data
      • (useful for me)
    • base
      • each widget has
      • on_mount
    • Static
      • Just content with base widget classes

  • message_pump.py

    • very important lib cause the entire textual console is just this file. look into!
