An event from a window.

Variants (Non-exhaustive)#

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Resized(PhysicalSize<u32>)

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

Moved(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.

Focused(bool)

The window gained or lost focus.

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

ScaleFactorChanged

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.

Fields of ScaleFactorChanged#

scale_factor: f64

The new scale factor.

new_inner_size: PhysicalSize<u32>

The window inner size.
