      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

              Then you must have missspelled something as that is all you need.
              Show excact code and the error

                  Creator did that when you promoted.

                        Try a clean build.
                        It seems correct.

                          I think we did the same so not sure why you cannot compile.

                                    Hmm . must be a cmake thing.

                                    The .h seems correctly spelled
                                    and this is in same project?

                                      #include "../include/agree_gui/matrixwidget.h"
