    when the connection fails the reason will be printed to the console.
    Also you can check the boolean return value of the connect-statement indicating if it failed or succeeded.

      Thanks for the response. On the Application Output console, this is what I get:
      @Object::connect: No such slot QWizardPage::connectionTest() in ../smif/setupwizard.cpp:272@

        you're missing the Q_OBJECT macro ;)
        @
        class DatabasePage : public QWizardPage
        {
        Q_OBJECT
        ....
        }
        @

          Hi,

          You are missing the Q_OBJECT macro in your DatabasePage declaration

            Thanks for pointing this out. Initially I had this macro and the error was the same.

              Where do you declare your DatabasePage class ?

                I have declared it in my setupWizard header file. This is how I have done it:
                @
                class setUpWizard : public QWizard
                {
                public:
                enum { Page_Intro, Page_Admin, Page_School, Page_Subjects,
                Page_Database, Page_Conclusion };
                setUpWizard();
                protected:

                private slots:
                void showHelp();

                };
                class DatabasePage : public QWizardPage
                {

                public:
                DatabasePage();

                int nextId() const;
                

                private slots:
                void connectionTest();

                private:
                QPushButton *testConnBttn;
                };@

                I get the following error when I assign Q_OBJECT macro to both setUPWizard class and DatabasePage class
                @
                C:\Users\GORDON\project\smif-build-desktop-Qt_4_7_4_for_Desktop_-_MinGW_4_4__Qt_SDK__Debug..\smif\setupwizard.cpp:202: error: undefined reference to `vtable for DatabasePage'
                @

                  This error usually appears when you didn't re-run qmake after adding/removing Q_OBJECT

                      You're welcome :)

                      Since it's working, you can update the thread's title by prepending [solved] so other forum users will know a solution has been found :)
