Button on ooimpress slide

Hi,

I've a code which create my own customized slide in
ooimpress. What I want
is that a button be placed on every slide and I need to
handle the click
event of the button. On every click of the button I need to
call my own
function.

Also I read in the developer guide about Protocol Handler
and Jobs, are they
related to such scenario as well or are they just for
buttons in the
toolbars ?

Thanks
