Thanks Tristan for you prompt response.
I did try your suggestion, but to no avail. After making the changes to my .cpp file, I now get a messages saying: "... error: 'GTK_CALLBACK' undeclared ..."


Perhaps this macro was not yet included in the 1.2.10 version, but in a later version, do you know?

I'll keep waiting, hopefully there'll be a GTK+ developer that will read this message and clear this for me, and the millions of GTK+ programmers who bought the "Learn GTK+ Programming in 21...." from SAMS.


Again, thank you, Tristan.

gtk_signal_connect uses functions with any signatures, they must all be cast to `void (*) ()' though first.

try:
gtk_signal_connect(GTK_OBJECT(btnExit), "clicked",
                   GTK_CALLBACK (Quit), NULL);

Cheers,
