Hide/Disable widgets or buttons from state

[chrisheib]

Hey, I have a widget for a song, which is:

On clicking on the 'x' I want some stuff to happen, and a function to set a field of the song 'x_pressed' to be set to true, and the x-button to disappear or get deactivated. Is there a widget with this functionality available? It would surprise me if I was the first one wanting to use this.

Code now:

    let skip = Button::new("✘")
        .on_click(|_: &mut EventCtx, song: &mut SongData, _: &Env| song.skip = true);

I want:

    let skip = Button::new("✘")
        .on_click(|_: &mut EventCtx, song: &mut SongData, _: &Env| {song.skip = true; song.x_pressed = true;})
        .enabled(|_: &mut EventCtx, song: &mut SongData, _: &Env| !song.x_pressed);

Hello, disable widgets are in progress see #1632, if you want to hide a button it should be possible with a ViewSwitcher on the Button and an SizedBox (cf. example view_switcher).

@HoNile thanks alot, using the viewswitcher works nicely for the time being!

    let skip_panel = ViewSwitcher::new(
        |data: &SongData, _env| data.is_last,
        |selector, _data, _env| match selector {
            false => Box::new(
                Button::new("✘")
                    .on_click(|_: &mut EventCtx, song: &mut SongData, _: &Env| song.skip = true),
            ),
            true => Box::new(Flex::column()),
        },
    );

Closing as a duplicate of #746.

@chrisheib the disabled state is merged, a disabled_if WidgetExt method is on the way (#1702).
