Change Focus After Enter/ Return Key Pressed in QLineEdit.

Hi.. I am just trying to create a sample Application Form, in that i have few QLineEdits, QCheckBox and QComboBoxes in it. When the user finished Editing in a QLineEdit and if the user Presses the Enter/Return Key, the QLineEdit’s Focus has to be changed to the Next Component.. How can i change a QLineEdit’s Focus to the next component when an Enter/Return key is Pressed. Note: I tried using an Evenfilters() method.. But No use…. :( The Focus is not changing…. :( Please give ur suggestions…
