    Hi there,

    I have a QStandardItemModel model (i.e,: QStandardItemModel *model;) made in mainwindow header code. I am passing it to a class SetDefault to put some default values in the model class. To do so, in mainwindow code I pass "&mode "and in class SetDefault get it as argument SetDefault (QStandardItemModel **_model). Next I set values in the passed model in such a way: (*_model)->setData(index,dat);
    Code runs, however, when i get the model back in mainwindow no changes was made to the model class! I have checked and the memory address of model class in the mainwindow is the same as the memory address of " *_model " in SetDefault class. But the model doesn't show changes after being back in the mainwindow.

    Any help is appreciated.

    Omid

      Hi and welcome to devnet,

      Please share the code where you create the model as well as the one you are using to modify it.

        why passing a double pointer instead of just the QStandardItemModel* ?
