@AliM93
its due to you having the auto generated file open
just press Close.

[mrjj]

Hmm
it seems cmake is confused.
about the includes.

Lets demote the widget and then you can add it to the dialog as you normal does.

Demote is important else you get error for ever.
sec.
shots

[mrjj]

ok go to
GridDialog UI
and then right click the widget

THIS IS ULTRA IMPORTANT as ELSE it will fail again and again as it still remembers the promotion.

[AliM93]

i have to do only this? morph into QWidget

[mrjj]

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.

[mrjj]

@AliM93
Yes to get rid of the promotion we tried.

[AliM93]

done, so now i have to include into file grid the matrix

[mrjj]

@AliM93
yes and see if it will accept it.
Then we need to new a matrixwidget in GridDialog

[AliM93]

so i add the include of matrix.h in the grid.cpp

[mrjj]

@AliM93
and it can compile?

[AliM93]

Build! thansk

[AliM93]

i run it but obviouslt i can't see anything

[AliM93]

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

[mrjj]

@AliM93
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

[AliM93]

done! but i only see the grid, not the content

[mrjj]

@AliM93
\o/
Good work.
I hope you learn a few Creator tricks.

we didnt paint the values yet :)

[AliM93]
