Removing and reinstalling mouse listeners would be one of the most

in the
hidden state. That is, add an event-filtering mechanism. Then you

have to tweak code in one place, instead of at every listener/sender
relationship throughout your entire code-base.
why would removing/adding listeners be complicated? If you have one
method that adds all the listeners and another that removes them,
these
can be called in setVisible() depending on the parameter. From my
point
of view this is easier than adding an event filtering mechanism.
It's probable I'm missing an important design/implementation issue
here, so please would someone explain :)
