setLabel in QprogressDialog

hi, I create a progress dialog from disigner and subclassedit; then I need set its label but the error below occur...why this?

Code:

---

myProgressDialog* progress = new myProgressDialog (steps, this, "progress", TRUE );
QLabel* l = new QLabel ("progress", 0);
progress->setLabel(l);
 error C2039: 'setLabel' : is not a member of 'myProgressDialog'

---

...also other members get same error.....

How did you define that subclass? Maybe you forgot to add "public" before the superclass name?

Code:

---

class myProgressDialog : public progressDialog {
	Q_OBJECT
public:
	myProgressDialog(int steps, QWidget* creator=0, const char* name=0, bool modal=FALSE, WFlags f =0);
	~myProgressDialog();	
};

What is that progressDialog class? If it was generated by uic from .ui file, then it only contains member variables (public, AFAIR) named in the same way as in Qt Designer --- just see the header generated by uic.

progressDialog.h in ui directory is a class that inherit from QDialog and not from QProgressDialog..is this problem? I designed a dialog called progressDialog from designer;but I'd ike design it and make it inherit from QProgressDialog. What do I have to do? How do I change it? Do you understand what I'd like do? thanks

Yes, your class is a QDialog not a QProgressDialog, so you can't use QProgressDialog's methods.

Unfortunately you can't design custom dialog that inherits from QProgressDialog, because QProgressDialog creates its own layout. Either create your own dialog that behaves like QProgressDialog or customize QProgressDialog using setBar(), setCancelButton() and setLabel() methods.
