Hi, thanks for reply.
I tried to add signal but could not run.
Here is my polygon.cpp code:
#include "polygon.h"
#include "point.h"
#include <QPainter>
#include <stdio.h>
#include <iostream>
#include <sstream>
#include <QGraphicsSceneDragDropEvent>
#include <QFocusEvent>
#include "DeclarativeDragDropEvent.h"
using namespace std;
using namespace Qt;
Polygon::Polygon(QDeclarativeItem *parent)
: QDeclarativeItem(parent)
{
// need to disable this flag to draw inside a QDeclarativeItem
setFlag(QDeclarativeItem::ItemHasNoContents, false);
setFlags(ItemIsSelectable|ItemIsMovable|ItemIsFocusable);
setAcceptDrops(true);
}
{
}
cout<<"focusin"<<endl;
}
QRectF Polygon
::boundingRect() const{
QVector<QPointF> vPnt=listToVector(m_vertices);
}
{
QVector<QPointF> vPnt=listToVector(m_vertices);
return path;
}
...
{
painter->setPen(pen);
painter
->setRenderHints
(QPainter::Antialiasing,
true);
QVector<QPointF> vPnt=listToVector(m_vertices);
painter
->setBrush
(QBrush(m_color,Qt
::SolidPattern));
painter
-> drawPolygon
(QPolygonF(vPnt
),Qt
::OddEvenFill);
}

QVariant Polygon::itemChange(GraphicsItemChange change, const QVariant &value)
{
return QGraphicsItem::itemChange(change, value);
}
void Polygon::focusInEvent ( QFocusEvent * event ){
cout<<"focusin"<<endl;
}

painter->setBrush(QBrush(m_color,Qt::SolidPattern));
painter-> drawPolygon(QPolygonF(vPnt),Qt::OddEvenFill);

I can see a polygon, but why focusInEvent is not called?
As you can see, i override boundingRect ans shape but no result.
I was doing nearly same things in Qt with C++ without QML.
Thanks for any idea.
