Re: mouse enter/leave notifications for insenstive widgets

[Praveen Innamuri <ajay praveen2002 gmail com>]

Thanks for your reply. But that might go wrong if mouse enter signal is
generated for widget-1 itself. (Suppose, some part of the widget-1 is
exposed, then that logic might not be useful).
I want to know whether mouse enter signal generated for widget-1 is due to
the mouse entering into insenstive widget-3. I tried using
gdk_window_at_pointer() to get the widget-3 when the mouse is entered on it.
However, even that API is returning me the widget-1 itself (as it is the
parent though widget-3 is actually drawn on top of widget-2) as widget-3 is
insensitive :(
Or, to prevent such enter/leave signals when mouse enters or leave
insensitive widgets.
