display <-
inspect_handlers: chainChain of handler
objects used to support debugging tools. This chain is shared by all
displays: it is display_manager <-inspect_handlers. When
an event occurs on a window and this chain is non-empty, the handlers in
this chain are tried before the normal event-handling procedure.
xpce searches for the deepest nested graphical that overlaps the
event-position.
A possible event focus is ignored. If the event matches the type of the
handler, the message of the handler is executed with the following
argument binding:
If this message succeeds, the event is considered to be dealt with.
