undefined reference to `vtable for MyClass' [SOLVED]

I create seven custom widget, all in the same way. Now, with the eighth I've got this error code when I compile that I don't understand.

grptransmitterpoweroptions.o: In function `GrpTransmitterPowerOptions':
/home/paceyiv/workspace/QtProjects/MatrixTestTool/test/TestFirmwareVersion/../../src/grptransmitterpoweroptions.cpp:12: undefined reference to `vtable for GrpTransmitterPowerOptions'
