I never have had as much trouble with anything I can remember.
As you suggested I setup a new class "MyDrawingFrame" and implemented it as best as I could. It compiles without any warnings
Qt Code: 
  1. #ifndef MYDRAWINGFRAME_H
  2. #define MYDRAWINGFRAME_H
  3.  
  4. #include "baseform.h"
  5. #include <qframe.h>
  6. #include <qpainter.h>
  7.  
  8. class MyDrawingFrame : public  QFrame
  9. {

Great, but how do I access it to set the values of the variables and activate the paint event itself??. If I "#include "mydrawingframe.h" in my "baseframe.cpp" or anyplace else for that matter I get an
/home/pete/Desktop/pm-straight-C/pm/mydrawingframe.h:65: multiple definition of `MyDrawingFrame:aintEvent(QPaintEvent*)'
baseform.o:/home/pete/Desktop/pm-straight-C/pm/mydrawingframe.h:65: first defined here
collect2: ld returned 1 exit status
make: *** [pm] Error 1
I have also tried setting up a "mydrawingframe.cpp" but I could not get a "MyDrawingFrame::MydrawingFrame( Q??? *parent ) : Q???
t(parent) that did not give an error when compiling.
Sorry to be so long winded, but I am desperate. What in H--- am I missing??? All I want to do is draw some lines of a QFrame widget!!!!!
