What does WPF use to capture mouse and keyboard input?

Question

I globally (system-wide) filter certain mouse clicks using SetWindowsHookEx and WH_MOUSE_LL. The problem is it doesn\'t work for WPF applications (

Answer 1

• WPF Window creates HwndSource (Window.CreateSourceWindow).
• HwndSource creates HwndWrapper (HwndSource.Initialize).
• HwndWrapper creates Win32 window with window procedure that delegate Windows messages to hooks, specified by HwndSource.
• One hook is the HwndSource.InputFilterMessage that delegate Windows messages to four input providers: stylus, mouse, keyboard, appcommand.
• Provider parses appropriate Windows message and invokes InputManager to raise input events on elements.

HwndMouseInputProvider process messages such as WM_MOUSEMOVE, WM_LBUTTONDOWN, etc. So I think there is no DirectInput used to handle mouse and keyboard input.
