Struct winsafe::guard::ReleaseCaptureGuard

source · 
pub struct ReleaseCaptureGuard<'a, H>
where
    H: user_Hwnd,
{ /* private fields */ }
Available on crate features kernel and user only.
Expand description

RAII implementation for HWND which automatically calls ReleaseCapture when the object goes out of scope.

Implementations§

source§

impl<'a, H> ReleaseCaptureGuard<'a, H>
where H: user_Hwnd,

source

pub const unsafe fn new(hwnd: &'a H, hwnd_prev: Option<HWND>) -> Self

Constructs the guard by taking ownership of the handles.

§Safety

Be sure you must call ReleaseCapture at the end of scope.

source

pub const fn prev_hwnd(&self) -> Option<&HWND>

Returns a handle to the window that had previously captured the mouse, if any.
