This will be very hard to explain but i will try anyway

i have a project called test .....it has test.cpp test.h & update.cpp update.h ....i created a QT dialog that displays on startup, this works fine.....i have added QlineEdit box and a pushButton. In test.cpp when i press the pushButton i can succesfully add text to the lineEdit1 ..using lineEdit1->setText ("wow it worked"); ......but i want a class form update.cpp to be able to add the text to lineEdit1 but it fails with update.cpp:35: error: `lineEdit1' undeclared (first use this function).

the easiest way is to download the project from here and it should all make sense than ;-)

Thanks

The declaration of lineEdit1 (as a QLineEdit *)  and it's new/delete seem to have gotten lost in the shuffle.  It'll have to be public if you want update to see it and, even then it'll have to be explicitely scoped (::).

I think you could use pointers. So the update class will have a pointer to the QT edit box.
