ImageViewer: ActionCallBack not called if there are actions associated with mouse buttons

I'm using the C++ ImageViewer v. 15.0.0.3 (5/2 patch).
I enable ActionCallBacks and I succesfully receive mouse events but if I set a default action associated with a mouse event, I don't receive the callback call anymore. See below code:



EnableActionCallBack(TRUE);
SetAction(CONTAINER_ACTION_WINDOWLEVEL, CONTAINER_MOUSE_BUTTON_LEFT, 0);

If I don't set the action for left mouse button, I receive the callback event.
Is this by design and if true is there any other way to intercept events when a default action is set?

Hello,

The callback only handles user-defined action events. It doesn't work with built-in (default) actions.

If you need to associate the mouse with a built-in action AND get mouse events at the same time, you might be able to do that by sub-classing the container viewer's window. To obtain the window handle, use the LImageViewer::GetWindowHandle() function. For more information about the subclassing, please refer to Microsoft Windows API documentation.
