Hi Jacek,

    Valery Fine is right and you should not mix Qt and TG classes in the 
same source file. Please, see if you can re-organize your code, either use 
a TGButton or a QButton. If you are only interested in using the Qt 
TVirtualX backend then there is no need to include any Qt header files at 
all, just use TG and the widgets will be rendered, low level, by Qt via the 
libRQt plugin.


Cheers, Fons.
