pointer at QMainWindow

[mattia]

Hello, if i have created with QT Designer a class called ui_class.h with the main window layout and at the and i have declared this namespace:

namespace Ui {
    class MainWindowClass: public Ui_MainWindowClass {};
}

namespace Ui {
    class MainWindowClass: public Ui_MainWindowClass {};
}

To copy to clipboard, switch view to plain text mode 

then i've made class.h in this way

#include <QtGui/QWidget>
#include "modify.h"
class class : public QMainWindow
{
    Q_OBJECT
 
public:
    class();
    ~class();
private:
    Ui::MainWindowClass ui;
    Modify *modify;
};

#include <QtGui/QWidget>
#include "modify.h"
class class : public QMainWindow
{
    Q_OBJECT

public:
    class();
    ~class();
private:
    Ui::MainWindowClass ui;
    Modify *modify;
};

To copy to clipboard, switch view to plain text mode 

and the class.cpp

#include <QtGui>
#include "class.h"
 
 
class::class()
{
	ui.setupUi(this);
	modify = new Modify(this);
 
}
 
server::~server(){}

#include <QtGui>
#include "class.h"


class::class()
{
	ui.setupUi(this);
	modify = new Modify(this);
	
}

server::~server(){}

To copy to clipboard, switch view to plain text mode 

how is the constructor in modify.h? cos i want to pass at the modify.h a pointer at the "MainWindowClass ui" to have access at all the widget that i have in ui_class.h.
Is it possibile?
