Your statement is still not helpful because you don't describe what the 
conflict is. So, I'll try with a couple of questions. 1) What happens 
when you just click push button 1? 2) What happens when you click push 
button 1 then click push button 2? 3)How is this different from what you 
want to happen?

You can use the sender() function in the run_timer slot. See the Qt 
documentation.
