Enum WindowEvent

#[non_exhaustive]
pub enum WindowEvent {
    Resized(PhysicalSize<u32>),
    Moved(PhysicalPosition<i32>),
    CloseRequested {
        api: CloseRequestApi,

    Focused(bool),

}

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.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

api: CloseRequestApi

An API modify the behavior of the close requested event.

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

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

scale_factor: f64

The new scale factor.

new_inner_size: PhysicalSize<u32>

The window inner size.

DragDrop(DragDropEvent)

An event associated with the drag and drop action.

ThemeChanged(Theme)

The system window theme has changed. Only delivered if the window theme is None.

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

Platform-specific

• Linux: Not supported.
