making a class aware of the gui

[aegis]

hi,

i have a form design that i implement using the multiple inheritance approach, so i have a class {i name it gui} that represents my form

class gui : public QDialog, private Ui::mainFormGUI
 {
     Q_OBJECT
 
     //the constructor
     public:
     	gui (QWidget *parent = 0);
 
     //the buttons of the functions....
     private slots:
 
     private:
     typeA test;
};

class gui : public QDialog, private Ui::mainFormGUI
 {
     Q_OBJECT

     //the constructor
     public:
     	gui (QWidget *parent = 0);

     //the buttons of the functions....
     private slots:

     private:
     typeA test;
};

To copy to clipboard, switch view to plain text mode 

the problem is that i want to make typeA access the gui interface....{for example write on a QTextEdit..... How can i do this?

i thought that i could pass to the typeA class a {this}pointer of gui {i.e. gui* p_gui} and then access the QTextEdit from p_gui but unfortunatelly it doesn't work....

any other ideas?

thanks in advance ,
