pub enum GuiContextEvent {
    Resize,
}

Events that directly interact with the GuiContext. Used to trigger resizes.

Variants

Resize

Resize the window to match the current size reported by the ViziaState’s size function. By changing the plugin’s state that is used to determine the window’s size before emitting this event, the window can be resized in a declarative and predictable way:

// Assuming there is some kind of state variable passed to the editor, likely stored as a
// `#[persist]` field in the `Params` struct:
let window_state = Arc::new(AtomicBool::new(false));

// And this is the `ViziaState` passed to `create_vizia_editor()`:
ViziaState::new(move || {
    if window_state.load(Ordering::Relaxed) {
        (800, 400)
    } else {
        (400, 400)
    }
});

// Then the window's size can be toggled between the two sizes like so:
fn toggle_window_size(cx: &mut EventContext, window_state: Arc<AtomicBool>) {
    window_state.fetch_xor(true, Ordering::Relaxed);

    // This will cause NIH-plug to query the size from the `ViziaState` again and resize the
    // windo to that size
    cx.emit(GuiContextEvent::Resize);
