GetWindowDC function Null safety user32
- int hWnd
The GetWindowDC function retrieves the device context (DC) for the entire window, including title bar, menus, and scroll bars. A window device context permits painting anywhere in a window, because the origin of the device context is the upper-left corner of the window instead of the client area.
HDC GetWindowDC(
HWND hWnd
);
Implementation
int GetWindowDC(int hWnd) {
final _GetWindowDC = _user32.lookupFunction<IntPtr Function(IntPtr hWnd),
int Function(int hWnd)>('GetWindowDC');
return _GetWindowDC(hWnd);
}
