Struct RawWindow 

pub struct RawWindow<'a> {
    pub _marker: &'a PhantomData<()>,
}

A raw window type that contains fields to access the HWND on Windows, GTK object pointers on Linux

Ownership

Unlike the WindowDispatch getters, the GTK pointers here are transfer none: they are borrowed from the window that is being created and are only valid for the duration of the callback that receives this struct. Wrap them with glib’s from_glib_none (which takes its own reference) and do not store them - the 'a lifetime is not enforced by the raw pointers, so retaining one past the callback dereferences freed memory.

The GTK major version of the objects is the one the runtime was built against, so consumers must wrap them with matching bindings.

Fields

_marker: &'a PhantomData<()>

Ties this struct to the lifetime of the window the pointers above are borrowed from.
