Enum Event 

#[non_exhaustive]
pub enum Event {
    Created,
    Resized,
    Moved,
    Foregrounded,
    Backgrounded,
    Focused,
    Unfocused,
    Hidden,
    Showed,
    Closed {
        window_id: WindowId,
    },
}

Represents events that can be observed on 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.

Created

The window was created.

Resized

The window was resized.

Moved

The window was moved.

Foregrounded

The window was brought to the foreground. This event does not mean the window has gained input focus.

Backgrounded

The window was backgrounded. It is opposite of Event::Foregrounded.

Focused

The window was focused.

Platform-specific

• Windows: This event is same as Event::Foregrounded. So this event and Foregrounded event are always dispatched together.
• macOS: On macOS, a window does not lose focus even when miniaturized. Therefore, this event will not be dispatched when the window is deminiaturized.

Unfocused

The window was unfocused.

Platform-specific

• Windows: This event is same as Event::Backgrounded. So this event and Backgrounded event are always dispatched together.
• macOS: On macOS, a window does not lose focus even when miniaturized. Therefore, this event will not be dispatched when the window is miniaturized

Hidden

The window was hidden.

Showed

The window was showed.

Platform-specific

• Windows: This event may not occur until after the observer has started and the first Hidden event has been triggered. Example: When monitoring begins while the window is minimized to the taskbar, and then the window is opened from the taskbar.

Closed

The window was closed.

Fields

window_id: WindowId

Trait Implementations

impl Clone for Event

fn clone(&self) -> Event

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Event

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Event

fn eq(&self, other: &Event) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
