Disable mouse on DataTable?

[fohrloop]

I have subclassed the DataTable and defined two "modes"

• One for moving the cursor
• One for moving the selected row

The fact that user is able to click with mouse also on the "moving the selected item" mode makes the app not work intuitively. I don't think mouse support is crucial for me, especially with the DataTable component. It would be easier to disable mouse actions than try to add support for it. I would like to either disable the ability to click cells (and change selected cell) on DataTable selectively or completely. I tried to override DataTable methods (without really checking what they do):

    async def _on_click(self, event) -> None: ...

    def action_select_cursor(self) -> None: ...

    def _on_mouse_move(self, event): ...

but that did not have any effect. I also tried:

    async def on_event(self, event: events.Event) -> None:
        if isinstance(event, MouseEvent):
            event.prevent_default()
        await super().on_event(event)

mentioned here but that does not work.

Any ideas how mouse clicks could be disabled?

You can use the prevent_default method as mentioned here: https://textual.textualize.io/guide/events/#preventing-default-behaviors

    async def _on_click(self, event: events.Click) -> None:
        event.prevent_default()
