pub struct WindowHandle<'a> { /* private fields */ }
Expand description

The handle to a window.

This is the primary return type of the HasWindowHandle trait. All pointers within this type are guaranteed to be valid and not dangling for the lifetime of the handle. This excludes window IDs like XIDs and the window ID for web platforms. See the documentation on the HasWindowHandle trait for more information about these safety requirements.

This handle is guaranteed to be safe and valid. Get the underlying raw window handle with the HasRawWindowHandle trait.

Implementations§

source§

impl<'a> WindowHandle<'a>

source

pub unsafe fn borrow_raw(raw: RawWindowHandle, active: ActiveHandle<'a>) -> Self

Borrow a WindowHandle from a RawWindowHandle.

Safety

The RawWindowHandle must be valid for the lifetime and the application must not be suspended. The Active object that the ActiveHandle was created from must be associated directly with the display that the window handle is associated with.
