Implementations

impl EventHandler

pub fn get_events(&self) -> &Vec<WidgetEvent>

pub fn clear_events(&mut self)

impl EventHandler

pub fn new() -> Self

pub fn handle_event(
    &mut self,
    event: Input,
    window_dimensions: Dimensions
) -> Option<WindowEvent>

Handle raw window events and update the Ui state accordingly.

This occurs within several stages:

1. Convert the user's given event to a RawEvent so that the Ui may use it.
2. Interpret the RawEvent for higher-level Events such as DoubleClick, WidgetCapturesKeyboard, etc.
3. Update the Ui's global_input State accordingly, depending on the RawEvent.
4. Store newly produced event::Uis within the global_input so that they may be filtered and fed to Widgets next time Ui::set_widget is called.

This method drives the Ui forward, and is what allows for using carbide's Ui with any window event stream.

The given event must implement the ToRawEvent trait so that it can be converted to a RawEvent that can be used by the Ui.
