error message-> undefined reference to 'xxx::QPaintDevice virtual table'

[Harald Fernengel]

Hi,

you probably forgot to include the generated .moc file. Just add a #include 
"blah.moc" at the end of your .cpp file and the error should disappear.

The gcc error-message is very misleading, it just tells you that there are 
undefined references in your code.
