Struct ReleaseCaptureGuard

pub struct ReleaseCaptureGuard<'a> { /* private fields */ }

Available on crate features kernel and user only.

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

Implementations

impl<'a> ReleaseCaptureGuard<'a>

pub const unsafe fn new(hwnd: &'a HWND, 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.

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

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

Trait Implementations

impl<'a> Drop for ReleaseCaptureGuard<'a>

fn drop(&mut self)
