Accessing the UI ! Help !

Thank you !

Did you initialize your ui and did you set the pointer guiClass right? Can we see the implementation?

guiClass ::guiClass (QWidget *parent)
    : QMainWindow(parent), ui(new Ui::guiClass )
{
    ui->setupUi(this);
 
 
    //this->ui->progressBar->setValue(80); // IT WORKS, but it is in guiClass    
 
    anotherClass *anotherclass = new anotherClass(this);
    anotherclass->anything();
 
}
 
guiClass ::~guiClass ()
{
    delete ui;
}

guiClass ::guiClass (QWidget *parent)
    : QMainWindow(parent), ui(new Ui::guiClass )
{
    ui->setupUi(this);


    //this->ui->progressBar->setValue(80); // IT WORKS, but it is in guiClass    

    anotherClass *anotherclass = new anotherClass(this);
    anotherclass->anything();

}

guiClass ::~guiClass ()
{
    delete ui;
}

@Lykurg : I don't use SIGNALS and SLOTS because I don't know how to use them
Moreover, I'd prefer to do it without signals and slots.

@fatjuicymole : what is a BP ?

PS: I'm a beginner.
