QGraphicsWidgets on QGraphicsGridLayout

[onurozcelik]

Hi

I subclass QGraphicsWidget and override boundingRect and paint methods.

Here is what I did shortly

CustomItem :: CustomItem()
{
    pen = QPen(QBrush(Qt::gray),5,Qt::SolidLine,Qt::RoundCap,Qt::BevelJoin);
}
 CustomItem :: ~CustomItem()
{
}
 
QRectF CustomItem::boundingRect() const
{
    return QRectF(0,0,102,5);
}
 
void CustomItem::paint(QPainter *painter,...)
{
    painter->setPen(pen);
    painter->drawLine(0,0,100,0);     
}

CustomItem :: CustomItem()
{
    pen = QPen(QBrush(Qt::gray),5,Qt::SolidLine,Qt::RoundCap,Qt::BevelJoin);
}
 CustomItem :: ~CustomItem()
{
}

QRectF CustomItem::boundingRect() const
{
    return QRectF(0,0,102,5);
}

void CustomItem::paint(QPainter *painter,...)
{
    painter->setPen(pen);
    painter->drawLine(0,0,100,0);     
}

To copy to clipboard, switch view to plain text mode 

And I added my CustomItem(s) to QGraphicsGridLayout

For this I used

QGraphicsScene *scene = new QGraphicsScene;
QGraphicsGridLayout *grid = new QGraphicsGridLayout;
 
CustomItem *custom1 = new CustomItem;
CustomItem *custom2 = new CustomItem;
 
grid->addItem(custom1,0,1);
grid->addItem(custom2,0,2);
 
QGraphicsWidget *container = new QGraphicsWidget;
container->setLayout(grid);
 
scene->addItem(container);

QGraphicsScene *scene = new QGraphicsScene;
QGraphicsGridLayout *grid = new QGraphicsGridLayout;

CustomItem *custom1 = new CustomItem;
CustomItem *custom2 = new CustomItem;

grid->addItem(custom1,0,1);
grid->addItem(custom2,0,2);

QGraphicsWidget *container = new QGraphicsWidget;
container->setLayout(grid);

scene->addItem(container);

To copy to clipboard, switch view to plain text mode 

When I do this
Two custom items had painted on each other(I guess because of paint draws them on same coordinates)
But I want them to paint one after another, I assume grid layout does it for me but it does not

How can I overcome this?

Note: I use QGraphicsWidget class instead of QGraphicsItem or QGraphicsLineItem because I think I may easily
create my user interface without supplying coordinates for each item.
