textual-cogs 0.0.3

Dialogs for use with the Textual package.

textual-cogs

A collection of Textual dialogs.

Dialogs included so far:

• Generic MessageDialog - shows messages to the user
• SaveFileDialog - gives the user a way to select a location to save a file
• TextEntryDialog - Ask the user a question and get their answer using an Input widget

Installation

You can install textual-cog using pip:

python -m pip install textual-cog

You also need Textual to run these dialogs.

Example Usage

Here is an example of creating a small application that opens the MessageDialog immediately. You would normally open the dialog in response to a message or event that has occurred, such as when the application has an error or you need to tell the user something.

from textual.app import App
from textual.app import App, ComposeResult

from textual_cogs.dialogs import MessageDialog
from textual_cogs import icons


class DialogApp(App):
    def on_mount(self) -> ComposeResult:
        def my_callback(value: None | bool) -> None:
            self.exit()

        self.push_screen(
            MessageDialog(
                "What is your favorite language?",
                icon=icons.ICON_QUESTION,
                title="Warning",
            ),
            my_callback,
        )


if __name__ == "__main__":
    app = DialogApp()
    app.run()

When you run this code, you will get something like the following:
