Method Description
BuildWindowCore ( HandleRef hwndParent ) : HandleRef
BuildWindowOverride ( HWND hwndParent ) : HWND

Default implementation of BuildWindowOverride, which just creates a simple "STATIC" HWND. This is almost certainly not the desired window, but at least something shows up on the screen. Override this method in your derived class and build the window you want.
DestroyWindowCore ( HandleRef hwnd ) : void
DestroyWindowOverride ( HWND hwnd ) : void

Default implementation of DestroyWindowCore, which just destroys the hosted window. If this is undesirable, override this method and provide alternative logic.
OnWindowPositionChanged ( Rect rcBoundingBox ) : void

WndProc ( IntPtr hwnd, int msg, IntPtr wParam, IntPtr lParam, bool &handled ) : IntPtr
WndProcOverride ( HWND hwnd, WM msg, IntPtr wParam, IntPtr lParam ) : IntPtr

Property Details

AsyncUpdateWindowPosProperty public_oe static_oe property

Specifies whether or not to set the window position of the hosted window asynchronously.
HwndHost depends on the LayoutUpdated event to synchronize the position of the HWND with the layout slot. However, when WPF gets into a recursive/nested layout loop, the LayoutUpdated event is not raised. Since we resize the hosted HWND in response to this event, if the hosted HWND contains an HwndSource, that HwndSource will run an immediate layout pass, but the LayoutUpdated event will not be raised. TODO: fix in 4.5?
