You say that the Designer preview shows the buttons correctly but your 
code does not. Does this mean that you are not using the Designer 
generated .ui files in your application? Are you trying to do everything 
in code?  It has been a while since I went through this so I don't 
remember the details, but I have had problems trying to duplicate 
Designer generated code in my own code, so I use the .ui files generated 
by Designer in my applications.
