How to work correctly with form elements from another form in qt?

Question

Qt

Hello! I'm trying to learn how to work with multiple forms in Qt.
There are two forms. Now in MainWindow I do this:

checkFileForm *fileF = new checkFileForm;
fileF->show();

Next, you need to change to checkFileForm, for example, the text of the button.
In checkFileForm.h I write:

public:
QPushButton *button;

checkFileForm.cpp

checkFileForm::checkFileForm(QWidget *parent) :
    QWidget(parent),
    ui(new Ui::checkFileForm)
{
    ui->setupUi(this);
    button = ui->pushButton;
}

Well, then through the signals and slots I do everything that I need.
The question is, is the mechanism for working with form elements from another form correct? Or is there a better way to work?

No need to do anything by hand, use QtDesigner's widget conversion mechanism for this purpose.
