QGraphicsItem hover event

[xgoan]

Hi. I'm subclassing a QGraphicsItem, but I can't recieve the hover events. I'm forgoting anything?

The code is below


#include "square.h"

#include <QtGui>

Square::Square(QPolygonF &polygon, uint row, uint col){
m_polygon=polygon;
m_row=row; m_col=col;
m_hover=false;
setAcceptsHoverEvents(true);
}

QRectF Square::boundingRect() const{
return m_polygon.boundingRect();
}

void Square::paint(QPainter *painter, const QStyleOptionGraphicsItem*, QWidget*){
if(m_hover) painter->setBrush(Qt::red);
painter->drawPolygon(m_polygon);
painter->drawText(boundingRect(), QString("%1x%2").arg(m_row).arg(m_col));
}

void Square::hoverEnterEvent(QGraphicsSceneHoverEvent*) {
m_hover=true;
}

void Square::hoverLeaveEvent(QGraphicsSceneHoverEvent*) {
m_hover=false;
}

Thanks, bye

Are you sure you are not receiving them? Maybe you should call QGraphicsItem::update() to schedule a repaint of the item?

Yes, I have test it using QMessageBox::information... And don't works, but if I use mousePressEvent it works

I think u just need to check if the item has mouse over it...

u can do it by the following


void Square::paint(QPainter *painter, const QStyleOptionGraphicsItem*, QWidget*)
{
if(option->state & QStyle::State_MouseOver) painter->setBrush(Qt::red);
painter->drawPolygon(m_polygon);
painter->drawText(boundingRect(), QString("%1x%2").arg(m_row).arg(m_col));
}

if(option->state & QStyle::State_MouseOver)

hope it helps :0

This solved it for me.
