Best way to simulate a key press?

[jspv]

I have a situation where I want the action taken from a button press to be an actual keypress to trigger the appropriate binding. Currently I'm using the internal App._press_keys() method which is working fine, but I know this isn't intended for public use. Is there a better way do to this?

    async def simulate_key(self, key: str) -> None:
        """Simulate a keypress"""
        await self._press_keys(key)

My working use case is a reused generic modal confirmation dialog - the dialog message and bindings for for "Y" and "N" responses are set each time before the dialog is displayed. I have the Button Widget presses simply simulate the "Y" and "N" responses to trigger the appropriate bindings rather than adding more logic to also customize the on_button_pressed logic.

To the best of my knowledge, there isn't an exposed method of simulating a key press. If I'm understanding correctly what you want to do (a yes/no dialog that has yes/no buttons but also handles Y/N key press), I think I'd start with something like this:

from textual.app import App, ComposeResult
from textual.widgets import Static, Button
from textual.containers import Horizontal

class Discussion1129( App[ str ] ):

    CSS = """
    #question {
        border: solid green;
    }

    Button {
        margin: 2;
    }
    """

    BINDINGS = [
        ( "y", "result( 'y' )", "" ),
        ( "n", "result( 'n' )", "" )
    ]

    def compose( self ) -> ComposeResult:
        yield Static( "A strange game. The only winning move is not to play. How about a nice game of chess?", id="question" )
        yield Horizontal(
            Button( "Yes please", id="y" ),
            Button( "No thanks", id="n" )
        )

    def on_button_pressed( self, event: Button.Pressed ) -> None:
        self.action_result( event.button.id )

    def action_result( self, answer: str ):
        self.exit( answer )


if __name__ == "__main__":
    print( Discussion1129().run() )

Thanks, really appreciate the code example.
