QStackedWidget - paintevent of widget not getting called

Hi,

Please consider the below codes:

File : mainwindow.cpp

Code:

---

mainwindow::mainwindow()
{   
    men = new menu1(this);
 
    q1 = new QPushButton("q1", men);
    connect(quran1, SIGNAL(clicked()), this, SLOT(qopen()));
 
    qs = new QStackedWidget(this);
    qs->addWidget(men);
    qs->setCurrentIndex(0); 
 
    show();
}

---

File : men.cpp

Code:

---

menu1::menu1(QWidget *parent) :
    QWidget(parent)
{
    resize(880, 580);
}
 
void menu1::paintEvent(QPaintEvent *)   // THIS JUST DRAWS A GREEN CURVE
{
    QPainter painter(this);
    painter.setRenderHint(QPainter::Antialiasing, true);
    QPainterPath path;
    path.moveTo(qrand() % 80, qrand() % 320);
    path.cubicTo(200, 200, 320, 80, 480, 320);
    painter.setPen(QPen(Qt::green, 8));
    painter.drawPath(path);
}

---

The problem is, whenever I run the above code, in the output, all I get is the pushbutton but not the green curve which is in the paintevent of menu1.


HOWEVER,

When I remove the QStackedWidget from mainwindow.cpp as shown below, I get both the pushbutton AND the green curve.

Code:

---

mainwindow::mainwindow()
{   
    men = new menu1(this);
 
    q1 = new QPushButton("q1", men);
    connect(quran1, SIGNAL(clicked()), this, SLOT(qopen()));
 
    show();
}

What is the problem with QStackedWidget? How can I get both the pushbutton and the curve to appear with the first example of mainwindow?

Regards.

Try giving the stacked widget a large enough size explicitly.

Yeah, your trick worked perfectly. Thanks.
