Function nih_plug_vizia::create_vizia_editor

pub fn create_vizia_editor<F>(
    vizia_state: Arc<ViziaState>,
    theming: ViziaTheming,
    app: F
) -> Option<Box<dyn Editor>>where
    F: Fn(&mut Context, Arc<dyn GuiContext>) + 'static + Send + Sync,

Create an Editor instance using a [vizia][::vizia] GUI. The ViziaState passed to this function contains the GUI’s intitial size, and this is kept in sync whenever the GUI gets resized. You can also use this to know if the GUI is open, so you can avoid performing potentially expensive calculations while the GUI is not open. If you want this size to be persisted when restoring a plugin instance, then you can store it in a #[persist = "key"] field on your parameters struct.

The GuiContext is also passed to the app function. This is only meant for saving and restoring state as part of your plugin’s preset handling. You should not interact with this directly to set parameters. Use the ParamEvents to change parameter values, and [GuiContextEvent] to trigger window resizes.

The theming argument controls what level of theming to apply. If you use ViziaTheming::Custom, then you need to call nih_plug_vizia::assets::register_noto_sans_light() at the start of your app function. Vizia’s included fonts are also not registered by default. If you use the Roboto font that normally comes with Vizia or any of its emoji or icon fonts, you also need to register those using the functions in nih_plug_vizia::vizia_assets.

See VIZIA’s repository for examples on how to use this.
