I am having trouble with the following code can someone explain what i am doing wrong. It is a main window application that has a dialog open up and im trying to create a button that saves the input from the user. but when i press the button it does gives the follwoing error

Object::connect: No such slot QDialog::SaveSettings() in serverDialog.cpp:6
Object::connect:  (sender name:   'pushButton_Save')
Object::connect:  (receiver name: 'Dialog')

Object::connect: No such slot QDialog::SaveSettings() in serverDialog.cpp:6
Object::connect:  (sender name:   'pushButton_Save')
Object::connect:  (receiver name: 'Dialog')

#ifndef SERVERDIALOG_H
#define SERVERDIALOG_H
 
#include "ui_serverDialog.h"
 
class ServerDialog: public QDialog, public Ui::Dialog
{
public:
    ServerDialog();
protected slots:
   void SaveSettings();
 
};
 
#endif // SERVERDIALOG_H

#ifndef SERVERDIALOG_H
#define SERVERDIALOG_H

#include "ui_serverDialog.h"

class ServerDialog: public QDialog, public Ui::Dialog
{
public:
    ServerDialog();
protected slots:
   void SaveSettings();

};

#endif // SERVERDIALOG_H

ServerDialog::ServerDialog()
{
        setupUi(this);
        connect(pushButton_Save, SIGNAL(clicked()), this, SLOT(SaveSettings()));
        connect(pushButton_Quit, SIGNAL(clicked()), this, SLOT(close()));
}
 
void ServerDialog::SaveSettings()
{
 
 
}

#include "serverDialog.h"

ServerDialog::ServerDialog()
{
        setupUi(this);
        connect(pushButton_Save, SIGNAL(clicked()), this, SLOT(SaveSettings()));
        connect(pushButton_Quit, SIGNAL(clicked()), this, SLOT(close()));
}

void ServerDialog::SaveSettings()
{


}

This was created using Qtcreator.
if i change the slot to close() it works perfectly. how would i get the method SaveSettings to run.

many thanks

Try adding the line "Q_OBJECT" before "public:" so moc knows to process the file.

That fixed it many thanks for the help

#ifndef SERVERDIALOG_H
#define SERVERDIALOG_H
 
#include "ui_serverDialog.h"
 
class ServerDialog:  public QDialog,  public Ui::Dialog
 
{
Q_OBJECT
public:
    ServerDialog();
public slots:
   void SaveSettings();
 
};
 
#endif // SERVERDIALOG_H

#ifndef SERVERDIALOG_H
#define SERVERDIALOG_H

#include "ui_serverDialog.h"

class ServerDialog:  public QDialog,  public Ui::Dialog

{
Q_OBJECT
public:
    ServerDialog();
public slots:
   void SaveSettings();

};

#endif // SERVERDIALOG_H

Out of interest, how did the close slot work without Q_OBJECT being present?

'Close' is part of QDialog, rather than part of ServerDialog.
