        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

                          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?

                                        yes, i try to change the .h include because sometimes i need to add the path

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