Hi,
I started developing my application on qtopia using qt designer.
I have little problem while compiling my application.I used signals and
slots from qtdesigner and it is giving some problem.
I created implementation file and inherited the class creted by QT designer.
i created the same slot which is there in the base class as virtual
function. Every thing i did fine. but it is not compiling. I am using suse
10.0. as my os. If i won't create implementation file and  if compile it is
compiling fine.
I am attaching my application also for ur refernce.

When i did make it is giving following message.
