Problem to rotate a QGraphicRectItem

Kiko007

My problem is when I rotate a rect, this no rotate very well. My centerPoint is (0, 0) corner left-up, but only rotate good when call it twice. I reimplemented mousepressEvent() for to call rotate(90) only.
Please help me how to rotate properly an Item.

It would be easier to help you if you provided more information, e.g.

post the code that you use
explain what you expect to happen
explain what you see happening

Excuse me.

I want to rotate the rectangle around its point of origin (0, 0) top-left, but when I click the item does not work properly (Figure A). Just after 3 click does what I expected (Figure B). How do I rotate at the first click.

Another issue is that without the variable num, rotates only once, when I try to make another click does nothing. I have broken my head but I can't get results.

My Qt version is Qt 5.0.1

@
#include <QApplication>
#include <QtWidgets>
#include "rectitem1.h"

int main(int argc, char *argv[])
{
QApplication a(argc, argv);

QGraphicsView *view = new QGraphicsView;
QGraphicsScene *scene = new QGraphicsScene;
RectItem1 *item = new RectItem1;
item->setRect(QRect(0, 0, 100, 200));

scene->addItem(item);
view->setScene(scene);
view->resize(600, 600);
view->show();

return a.exec&#40;&#41;;

}

#ifndef RECTITEM1_H
#define RECTITEM1_H

#include <QGraphicsRectItem>

class RectItem1 : public QGraphicsRectItem
{
public:
RectItem1();

protected:
void mousePressEvent(QGraphicsSceneMouseEvent *event);

};

#endif // RECTITEM1_H

#include "rectitem1.h"

RectItem1::RectItem1()
{
}

void RectItem1::mousePressEvent(QGraphicsSceneMouseEvent event)
{
static int num = 0;
setRotation(90++num);
QGraphicsRectItem::mousePressEvent(event);
}

I have just compiled your code
works perfectly

you have to click inside the rectangular item that you are adding
otherwise mouse event will not be passed to the RectItem1 object
