Context Menu & QGraphicsWidget

First of all concerning your composite item's ::boudingRect(), you really should "think about it" My guess is to merge every child item's bounding rect.

To ensure you computed the right boundingRect, add this code in your CompositeItem:aint() :

painter->save() ;
painter->setPen(Qt::yellow) ;
painter->setBrush(Qt::NoBrush) ;
painter->drawRect(boundinRect()) ;
painter->restore() ;

painter->save() ;
painter->setPen(Qt::yellow) ;
painter->setBrush(Qt::NoBrush) ;
painter->drawRect(boundinRect()) ;
painter->restore() ;

To copy to clipboard, switch view to plain text mode 

And try to right-click on your composite item, maybe it will suffice (didn't try so I'm not sure)

You are right buddy. I think seriously about boundingRect. (I edited the code)

QRectF CompositeItem::boundingRect() const
{
   FieldItem *child;
  QRectF rect(0,0,0,0);
  foreach(child,children)
 {
     rect = rect.united(child->boundingRect());
 }
 return rect;
}

QRectF CompositeItem::boundingRect() const
{
   FieldItem *child;
  QRectF rect(0,0,0,0);
  foreach(child,children)
 {
     rect = rect.united(child->boundingRect());
 }
 return rect;
}

I thinks its is a neat idea to unite child items boundingRects but this time
item can' t catch events like contextmenuevent, mousepressevent.
I tried to click everywhere inside boundingRect.
What may cause this?

sorry, I've no idea without seeing involved source code. It might come from an event you accept too early in the scene or not forwarded by a virtual method call, or even items are not selectable, etc.

I solved the problem temporarily. I rewrite paint. Now it looks as follows.

void CompositeItem::paint(QPainter *painter, const QStyleOptionGraphicsItem *option, QWidget *widget )
{
   painter->setPen(Qt::transparent);
   painter->drawRect(boundingRect());
 
   FieldItem *child;
   foreach(child,children)
   {
     child->paint(painter,option,widget);
   }
 }

void CompositeItem::paint(QPainter *painter, const QStyleOptionGraphicsItem *option, QWidget *widget )
{
   painter->setPen(Qt::transparent);
   painter->drawRect(boundingRect());
   
   FieldItem *child;
   foreach(child,children)
   {
     child->paint(painter,option,widget);
   }
 }

Now I can catch events occurs inside rectangle
