      Next step is to then include matrixwidget.h and
      make it like it.
      I dont know your structure so not sure why it dont see it.
      You have to make it like the include.

            yes and see if it will accept it.
            Then we need to new a matrixwidget in GridDialog

                      because we have to add the matrix in the widget, right?

                        yes.
                        You should still have the layout from before, correct ?
                        then in Grids constrcutor

                        GridDialog::GridDialog(QWidget *parent) :
                            QDialog(parent),
                            ui(new Ui::GridDialog)
                        {
                            ui->setupUi(this);
                        
                            MatrixWidget * m = new MatrixWidget (this);
                            ui->verticalLayout->addWidget(m); /// you name might differ for layout
                        
                        }
                        

                        We dont need the plain widget any more. you can delete it. we use the layout

                                  well do you have that version of paint ?

                                      // now we find out how big each box should be which area we have  divided with how many on x and y

                                      But it dont draw numbers ?
                                      That seems very odd.

                                      But you do see grid ?

                                          Ok that good news as it would be very impossible that numbers went missing :)

                                          what is remaining is the click logic and to actual draw the 1.

                                          how shall we draw 0 ones ?
                                          just no value in cell and cant be selected or what is the goal?
