Proper way to remove widgets

[artur-shaik]

How I can properly reload my view with new widgets, by removing old ones?

I've been poking around the source the past couple days and I haven't seen anything like def remove_widget. I think this might be intentional but I'm not sure. You could delete the Widget object from the View.widgets property but I haven't tried that yet. You could also try setting the visible property of your widget to False.

You could also overwrite an area with a widget with None in a GridView for example, by using add_widget or place. There isn't really a proper way to do it

I've tried to do self.view.widgets.clear(). Set becomes empty, but widgets still in view.

Ok, looks like find some hacky solution that works:

        if isinstance(self.view.layout, DockLayout):
            self.view.layout.docks.clear()
        self.view.widgets.clear()

@artur-shaik I was unable to get this to work outside of on_mount at the very start. How did you implement it?

[artur-shaik]

@stephenlutes I've implemented in inside textual event loop, not sure why you need it outside?

I may be going about this the wrong way. I am trying to clear everything within an action when a certain key is pressed.

Update
I was able to get it to work by moving it into on_key instead of binding to an action.
