Crazy over the QGraphicsScene/Item

[Morea]

I have added an customized QGraphicsPixmapItem to the Scene, but when I click on the item.. what can I say, it records it as a ordinary click on the scene, but if I click more than once very quickly, it also notice that the item is clicked.

(as a side note: if I click exactly in the left margin of the Item, it seems to respond to a slow single click.)

It's driving me crazy.

Here is code for the item

void Town::mousePressEvent(QGraphicsSceneMouseEvent* ev)
{
	Qt::MouseButtons btn = ev->buttons();
	if (btn & Qt::LeftButton)
	{
		qDebug()<<"You visited Lamerville";
	}
}

void Town::mousePressEvent(QGraphicsSceneMouseEvent* ev)
{
	Qt::MouseButtons btn = ev->buttons();
	if (btn & Qt::LeftButton)
	{
		qDebug()<<"You visited Lamerville";
	}
}

To copy to clipboard, switch view to plain text mode 

When I set the position for the item, I set it with integer coordinats. but I think that can hardly be the problem.

Here is code for the scene

void Game::mousePressEvent(QGraphicsSceneMouseEvent* ev)
{
	QPointF p = ev->buttonDownScenePos( Qt::LeftButton);
	int x,y;
	x=p.x()/SKAL;
	y=p.y()/SKAL;
	qDebug()<<"you pressed mouse on map"<<x<<y;

void Game::mousePressEvent(QGraphicsSceneMouseEvent* ev)
{
	QPointF p = ev->buttonDownScenePos( Qt::LeftButton);
	int x,y;
	x=p.x()/SKAL;
	y=p.y()/SKAL;
	qDebug()<<"you pressed mouse on map"<<x<<y;

SKAL is a constant for scaling purposes.

I'd be very happy for any suggestion. I guess there is a fundamental flaw... but what is it?

Did u subclass the pix item ??
if yes, while handling mousepress event.. try passing it to QGraphicsItem::mousePressEvent ()....

also how are town and game related ??

[Morea]

Yes I did this:

class Town :public QGraphicsPixmapItem {
        public:
                Town(QPoint p=QPoint(0,0));
                void mousePressEvent(QGraphicsSceneMouseEvent* ev);
        protected:
                QString name;
};

class Town :public QGraphicsPixmapItem {
        public:
                Town(QPoint p=QPoint(0,0));
                void mousePressEvent(QGraphicsSceneMouseEvent* ev);
        protected:
                QString name;
};

To copy to clipboard, switch view to plain text mode 

In the town.cpp file I have

void Town::mousePressEvent(QGraphicsSceneMouseEvent* ev)
{
        Qt::MouseButtons btn = ev->buttons();
        if (btn & Qt::LeftButton)
        {
                qDebug()<<"You visited Lamerville";
        }

void Town::mousePressEvent(QGraphicsSceneMouseEvent* ev)
{
        Qt::MouseButtons btn = ev->buttons();
        if (btn & Qt::LeftButton)
        {
                qDebug()<<"You visited Lamerville";
        }

To copy to clipboard, switch view to plain text mode 

}

Should I add a line

QGraphicsItem::mousePressEvent ();

QGraphicsItem::mousePressEvent ();

To copy to clipboard, switch view to plain text mode 

to the code? Where? In the beginning of the function?
Exactly, what will it accomplish?

town and game is related by populating the game ( a Scene) with towns (Items)

QVector<QPoint> cities = map->randomTownPositions(8);
        QPoint pos;
        Town* t;
        foreach (pos, cities)
        {
                t = new Town(pos);
                addItem(t);
                towns.push_back(t);
        }

QVector<QPoint> cities = map->randomTownPositions(8);
        QPoint pos;
        Town* t;
        foreach (pos, cities)
        {
                t = new Town(pos);
                addItem(t);
                towns.push_back(t);
        }

I think the "additem" will be enough, won't it?

[aamer4yu]

did u try adding QGraphicsItem::mousePressEvent () to ur mousepressevent ??

[Morea]

Sorry, I did something to solve it. I can't remember right now.
But I think it was somethign with mousPressEvent.. or.. no. I don't remember what it was.

[aamer4yu]

well.. if u remmeber what u did.. u may post it.. it may benefit me too if ur way is not known

[Morea]

I think it was something with adding the item to the scene or setting the parent.
