}
Expand description
Raw window handle for Win32.
Fields (Non-exhaustive)§
This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional
Struct { .. }
syntax; cannot be matched against without a wildcard ..
; and struct update syntax will not work.hwnd: NonZeroIsize
A Win32 HWND
handle.
hinstance: Option<NonZeroIsize>
The GWLP_HINSTANCE
associated with this type’s HWND
.
Implementations§
source§impl Win32WindowHandle
impl Win32WindowHandle
sourcepub fn new(hwnd: NonZeroIsize) -> Self
pub fn new(hwnd: NonZeroIsize) -> Self
Create a new handle to a window.
§Safety
It is assumed that the Win32 handle belongs to the current thread. This is necessary for the handle to be considered “valid” in all cases.
§Example
let window: HWND;
let mut handle = Win32WindowHandle::new(NonZeroIsize::new(window.0).unwrap());
// Optionally set the GWLP_HINSTANCE.
let hinstance = NonZeroIsize::new(unsafe { GetWindowLongPtrW(window, GWLP_HINSTANCE) }).unwrap();
handle.hinstance = hinstance;
