Widget Error Update

[Roy_CT]

src/email.cpp: In constructor 'Email::Email(QWidget*)':
src/email.cpp:5: error: invalid use of incomplete type 'struct Ui::dialogEmail'
src/email.h:8: error: forward declaration of 'struct Ui::dialogEmail'
src/email.cpp:7: error: invalid use of incomplete type 'struct Ui::dialogEmail'
src/email.h:8: error: forward declaration of 'struct Ui::dialogEmail'
src/email.cpp: In destructor 'virtual Email::~Email()':
src/email.cpp:12: warning: possible problem detected in invocation of delete operator:
src/email.cpp:12: warning: invalid use of incomplete type 'struct Ui::dialogEmail'
src/email.h:8: warning: forward declaration of 'struct Ui::dialogEmail'
src/email.cpp:12: note: neither the destructor nor the class-specific operator delete will be called, even if they are declared when the class is defined.

I can't add on to my first Widget Error so I am adding the extra infomation requested here
This is email.h :-

@
#ifndef EMAIL_H
#define EMAIL_H

#include <QtGui/QDialog>

namespace Ui
{
class dialogEmail;
}

class Email : public QDialog
{
Q_OBJECT

public:
Email(QWidget *parent = 0);
~Email();

public slots:
void accept();

private:
Ui::dialogEmail *ui;

};

#endif // EMAIL_H
@

and this is email.cpp :-

@
#include "email.h"
#include "ui_email.h"
#include <QSettings>
// added setup
Email::Email(QWidget *parent) : QDialog(parent), ui(new Ui::dialogEmail)
{
ui->setupUi(this);
}

Email::~Email()
{
delete ui;
}

void Email::accept()
{
QSettings settings("abycad.com","abycad");
}
@

Thanks for the help

EDIT: added @-tags for source code, Gerolf

I have checked my pro and Forms += email.ui is there.

Below is full compile output of my build :-

This reminds me of another post, still the same issue ?

to quote your code use "@" markers, it's more readable

Hem, I took your email.h, email.cpp, email.ui, and tried
@
qmake -pro
qmake -tp vc -r
@
it does compile...

All sounds your pro file does not contain the forms part:

@
FORMS += email.ui
