I have a WPF app with a usercontrol that contains a HwndHost. The HwndHost is created as follows:
hwndHost = CreateWindowEx(0, "static", "",
WS_CHILD | WS_VISIBLE,
0, 0,
hostHeight, hostWidth,
hwndParent.Handle,
(IntPtr)HOST_ID,
IntPtr.Zero,
0);
hwndControl = CreateWindowEx(0, "Static", "",
WS_CHILD | WS_VISIBLE | WS_CLIPCHILDREN
,
0, 0,
hostHeight, hostWidth,
hwndHost,
(IntPtr)PICTUREBOX_ID,
IntPtr.Zero,
0);
I then hook into the message pump using HwndSourceHook and loads of messages come through.
Except the ones I want i.e. WM_MOUSEMOVE, WM_MOUSEHOVER, WM_LBUTTONDOWN and WM_LBUTTONUP
Also the OnMouseLeftButtonDown event is not fired in the WPF code on the main window or the control, I assume because windows is trapping it and throwing it away.
Anybody know how I can get these to come through, either with or without using the WIN32 window messages?
