Expand description
A set of callbacks for an active window. If a callback is not implemented, it will do nothing by default, so it is only necessary to implement the callbacks you actually need.
Provided methods
fn on_start(
&mut self,
helper: &mut WindowHelper<UserEventType>,
info: WindowStartupInfo
)
fn on_start(
&mut self,
helper: &mut WindowHelper<UserEventType>,
info: WindowStartupInfo
)
Invoked once when the window first starts.
fn on_user_event(
&mut self,
helper: &mut WindowHelper<UserEventType>,
user_event: UserEventType
)
fn on_user_event(
&mut self,
helper: &mut WindowHelper<UserEventType>,
user_event: UserEventType
)
Invoked when a user-defined event is received, allowing you to wake up the event loop to handle events from other threads.
fn on_resize(
&mut self,
helper: &mut WindowHelper<UserEventType>,
size_pixels: Vector2<u32>
)
fn on_resize(
&mut self,
helper: &mut WindowHelper<UserEventType>,
size_pixels: Vector2<u32>
)
Invoked when the window is resized.
fn on_scale_factor_changed(
&mut self,
helper: &mut WindowHelper<UserEventType>,
scale_factor: f64
)
fn on_scale_factor_changed(
&mut self,
helper: &mut WindowHelper<UserEventType>,
scale_factor: f64
)
Invoked when the window scale factor changes.
fn on_draw(
&mut self,
helper: &mut WindowHelper<UserEventType>,
graphics: &mut Graphics2D
)
fn on_draw(
&mut self,
helper: &mut WindowHelper<UserEventType>,
graphics: &mut Graphics2D
)
Invoked when the contents of the window needs to be redrawn.
It is possible to request a redraw from any callback using WindowHelper::request_redraw.
fn on_mouse_move(
&mut self,
helper: &mut WindowHelper<UserEventType>,
position: Vector2<f32>
)
fn on_mouse_move(
&mut self,
helper: &mut WindowHelper<UserEventType>,
position: Vector2<f32>
)
Invoked when the mouse changes position.
Invoked when a mouse button is pressed.
Invoked when a mouse button is released.
fn on_key_down(
&mut self,
helper: &mut WindowHelper<UserEventType>,
virtual_key_code: Option<VirtualKeyCode>,
scancode: KeyScancode
)
fn on_key_down(
&mut self,
helper: &mut WindowHelper<UserEventType>,
virtual_key_code: Option<VirtualKeyCode>,
scancode: KeyScancode
)
Invoked when a keyboard key is pressed.
To detect when a character is typed, see the WindowHandler::on_keyboard_char callback.
fn on_key_up(
&mut self,
helper: &mut WindowHelper<UserEventType>,
virtual_key_code: Option<VirtualKeyCode>,
scancode: KeyScancode
)
fn on_key_up(
&mut self,
helper: &mut WindowHelper<UserEventType>,
virtual_key_code: Option<VirtualKeyCode>,
scancode: KeyScancode
)
Invoked when a keyboard key is released.
fn on_keyboard_char(
&mut self,
helper: &mut WindowHelper<UserEventType>,
unicode_codepoint: char
)
fn on_keyboard_char(
&mut self,
helper: &mut WindowHelper<UserEventType>,
unicode_codepoint: char
)
Invoked when a character is typed on the keyboard.
This is invoked in addition to the WindowHandler::on_key_up and WindowHandler::on_key_down callbacks.
fn on_keyboard_modifiers_changed(
&mut self,
helper: &mut WindowHelper<UserEventType>,

fn on_keyboard_modifiers_changed(
&mut self,
helper: &mut WindowHelper<UserEventType>,
state: ModifiersState
)
Invoked when the state of the modifier keys has changed.
