Flushing PyQt's Event Queue

[ff]

Hi, I am writing an app which models growth of a system over time
visually which is activated by button clicks, and when the loop
finishes running i dont want any events [mainly clicking on buttons]
that happened during the loop to be put into action since then it may
run multiple times without the user realising what they have done,

is there way to flush the event queue when the loop has finished??
