This is indeed a bit strange. What's happening here is that the virtual 
keyboard's OK button is generating a key event for the Enter key which 
is sent to the QLineEdit, but since QLineEdit ignores this key, it is 
sent to the QDialog instead. QDialog handles key events and will accept 
its button box when it sees an Enter key. In the case of a virtual 
keyboard, which works on a particular line edit, this is unexpected, so 
I wouldn't mind it if you reported this as a bug, since it should really 
be part of the platform theme (on Windows, enter should accept the 
dialog, whereas on Android this does not make sense).

As a work-around, you can add an event filter to the QLineEdit and 
filter out the Enter key presses by returning true whenever you see them.
