setting terminal window title

[t184256]

To be added by @willmcgugan

I can set title and subtitle for the textual-rendered header, but I cannot update the terminal window title once I start using textual. The standard (linux) trick of sys.stderr.write("\x1b]2;TEXT\x07"); sys.stderr.flush() works before I initialize textual, but stops working afterwards.

I think you can do self.app.console.set_window_title("My title")

And to show that off, here's a wee stand-alone Textual app using it:

from textual.app        import App, ComposeResult
from textual.containers import Vertical
from textual.widgets    import Header, Footer, Label, Input

class SetTitleApp( App[ None ] ):

    CSS = """
    Label {
        margin-left: 1;
    }

    Vertical {
        align: center middle;
    }
    """

    def compose( self ) -> ComposeResult:
        yield Header()
        yield Vertical(
            Label( "Set the terminal title:" ),
            Input( placeholder="Set the terminal title here" )
        )
        yield Footer()

    def on_input_changed( self, event: Input.Changed ) -> None:
        self.console.set_window_title( event.value )

if __name__ == "__main__":
    SetTitleApp().run()

Indeed you can, thank you!
