[Sugar-devel] [PATCH] Make the child window of the event box insisible

[Simon Schampijer]

We do use the EventBox only to receive events, hence the
window that the even box creates should be a GDK_INPUT_ONLY
window, which means that it is invisible and only serves to
receive events [1].

A test program to see this is at [2].
