Describes an event from a Window.

Variants

Resized(PhysicalSize<u32>)

Tuple Fields

0: PhysicalSize<u32>

The size of the window has changed. Contains the client area’s new dimensions.

Moved(PhysicalPosition<i32>)

Tuple Fields

0: PhysicalPosition<i32>

The position of the window has changed. Contains the window’s new position.

CloseRequested

The window has been requested to close.

Destroyed

The window has been destroyed.

DroppedFile(PathBuf)

Tuple Fields

0: PathBuf

A file has been dropped into the window.

When the user drops multiple files at once, this event will be emitted for each file separately.

HoveredFile(PathBuf)

Tuple Fields

0: PathBuf

A file is being hovered over the window.

When the user hovers multiple files at once, this event will be emitted for each file separately.

HoveredFileCancelled

A file was hovered, but has exited the window.

There will be a single HoveredFileCancelled event triggered even if multiple files were hovered.

ReceivedCharacter(char)

Tuple Fields

0: char

The window received a unicode character.

Focused(bool)

Tuple Fields

0: bool

The window gained or lost focus.

The parameter is true if the window has gained focus, and false if it has lost focus.

KeyboardInput

Fields

device_id: DeviceId

input: KeyboardInput

is_synthetic: bool

If true, the event was generated synthetically by winit in one of the following circumstances:

• Synthetic key press events are generated for all keys pressed when a window gains focus. Likewise, synthetic key release events are generated for all keys pressed when a window goes out of focus. Currently, this is only functional on X11 and Windows

Otherwise, this value is always false.

An event from the keyboard has been received.

ModifiersChanged(ModifiersState)

Tuple Fields

0: ModifiersState

The keyboard modifiers have changed.

Platform-specific behavior:

• Web: This API is currently unimplemented on the web. This isn’t by design - it’s an issue, and it should get fixed - but it’s the current state of the API.

CursorMoved

Fields

device_id: DeviceId

position: PhysicalPosition<f64>

(x,y) coords in pixels relative to the top-left corner of the window. Because the range of this data is limited by the display area and it may have been transformed by the OS to implement effects such as cursor acceleration, it should not be used to implement non-cursor-like interactions such as 3D camera control.

modifiers: ModifiersState

👎 Deprecated:

Deprecated in favor of WindowEvent::ModifiersChanged

The cursor has moved on the window.

CursorEntered

Fields

device_id: DeviceId

The cursor has entered the window.

CursorLeft

Fields

device_id: DeviceId

The cursor has left the window.

MouseWheel

Fields

device_id: DeviceId

delta: MouseScrollDelta

phase: TouchPhase

modifiers: ModifiersState

👎 Deprecated:

Deprecated in favor of WindowEvent::ModifiersChanged

A mouse wheel movement or touchpad scroll occurred.

MouseInput

Fields

device_id: DeviceId

state: ElementState

button: MouseButton

modifiers: ModifiersState

👎 Deprecated:

Deprecated in favor of WindowEvent::ModifiersChanged

An mouse button press has been received.

TouchpadPressure

Fields

device_id: DeviceId

pressure: f32

stage: i64

Touchpad pressure event.

At the moment, only supported on Apple forcetouch-capable macbooks. The parameters are: pressure level (value between 0 and 1 representing how hard the touchpad is being pressed) and stage (integer representing the click level).

AxisMotion

Fields

device_id: DeviceId

axis: AxisId

value: f64

Motion on some analog axis. May report data redundant to other, more specific events.

Touch(Touch)

Tuple Fields

0: Touch

Touch event has been received

ScaleFactorChanged

Fields

scale_factor: f64

new_inner_size: &'a mut PhysicalSize<u32>

The window’s scale factor has changed.

The following user actions can cause DPI changes:

• Changing the display’s resolution.
• Changing the display’s scale factor (e.g. in Control Panel on Windows).
• Moving the window to a display with a different scale factor.

After this event callback has been processed, the window will be resized to whatever value is pointed to by the new_inner_size reference. By default, this will contain the size suggested by the OS, but it can be changed to any value.

For more information about DPI in general, see the dpi module.

ThemeChanged(Theme)

Tuple Fields

0: Theme

The system window theme has changed.

Applications might wish to react to this to change the theme of the content of the window when the system changes the window theme.

At the moment this is only supported on Windows.
