I want to call parent widget's event from child widget .

I am having eventfilter in QDialog , in that i am checking keypress event and if it is up key i am doing some actions , i am having my own widget placed in that QDialog , from my child widget i want to call the up event explicitly ,

This is like sendMessage() in VC++.

How to do this in qt?

can we use emit() forthis ? if yes , how to call events using emit()?
