How to interchange the behaviour of the Keys

[Vikram.Saralaya]

The code snippet you sent works fine.

The output I get when I run it:

before functionality
your key value is 16777234
inside if
before functionality
your key value is 16777236
before box display
before box display

before functionality
your key value is 16777234
inside if
before functionality

before box display

To copy to clipboard, switch view to plain text mode 

May be make sure the proper widget is receiving the event. Rest everything is fine.
