@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
alt text

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
