hmmm 

sorry, I don't know what to tell you.


I haven't played with it in a while.  I also do most things directly in C++ 
and as little as possible with the designer.


I would try a Qt specific group or list if you don't have paid support.


I wish I knew the answer.


B-)


P.S.  You might want to try changing the datatype in either the database field 
or the lineedit if possible.  I simply don't remember
