    Again, select the File New as when we made the widget.

    alt text

    Choose Designer Form class

    Then choose a dialog

    alt text

    Give it a good name
    alt text

    Press NExt, NExt

    Now you have this and you add a QWidget to it and promote it.

            Hi
            Nope. When you use promotion, Creator adds the needed included. You tell it what file
            in the promotion dialog. ( look at image)


            and after you promoted it.
            Then right click outside the widget and add a layout so our widget follow size of dialog automatically

                    Ok then we need button to show dialog.
                    so add button
                    Right click it and goto slot.
                    Choose Released
                    Add the code. ( want me to show that ?)

                        Where ever you want to open it from.
                        Main win sounds good.

                        #include "GridDialog.h"
                        
                        void MainWindow::on_pushButton_released()
                        {
                            GridDialog dia; 
                            dia.exec();
                        }

                          @mrjj which is the difference between released and clicked? (curiosity)

                          Done.

                            Clicked = triggers when you click
                            Release = triggers when you release the left mouse button.
                            You can use any of them.

                                  Mind the case

                                  Griddialog = new griddialog(this); <<< that is not correct class name and u missed * and name

                                  GridDialog * dia = new GridDialog (this);

                                  GridDialog <<< class name
