Implementations

impl GUI

pub fn new(context: &Context) -> Result<Self, Error>

Creates a new GUI.

pub fn update<F: FnOnce(&CtxRef)>(
    &mut self,
    frame_input: &mut FrameInput,
    callback: F
) -> Result<bool, Error>

Initialises a new frame of the GUI and handles events. Construct the GUI (Add panels, widgets etc.) using the egui::CtxRef in the callback function. This function returns whether or not the GUI has changed, ie. if it consumes any events, and therefore needs to be rendered again.

pub fn render(&mut self) -> Result<(), Error>

Render the GUI defined in the update function. Must be called in a render target render function, for example in the callback function of Screen::write.
