Unsolved wait for slot to finished

[s002wjh]

in my function i'm constantly emit a signal, but i would like to only emit the signal after my slot function are finished, anyway to do that?

if (canEmit) {
  canEmit = false;
  emit mySignal();
}
// Slot:
void mySlot() {
  doSomething();
  emit processingFinished();
}
// The previous class, slot:
void onProcessingFinished() {
  canEmit = true;
}
