You don't need a different QThread sub-class for each method. You only need 
one that takes an argument that is the callable to call from run() - just 
like you were passing it as "target=" before.

How many event types you need depends on how many different things you want to 
do in the main thread. You could get away with just one if you used it to 
pass a reference to another callable which the event handler in the main 
thread called to do the updates.
