This is what I get from my debugger :
Program received signal SIGSEGV, Segmentation fault.
0x080498d3 in MainWindow::translate (this=0x0) at Poligono.cpp:75
75 mygl->translate(1.0,1.0,0.0);

Seems to me that when I call the translate() method the object mygl is no
longer available. But is there a way of calling this method without making
this parse
((MainWindow*)v)->translate(); ? Or at least do it differently?
I guess that here is where the pointer is not available anymore or even
before.
This is my main function... I had forgotten..
#include "Poligono.h"
#include "T.h"
int main(int argc, char** argv){
MainWindow win(50,100, 800, 600, "Poligono");
return Fl::run();
}
