Move a QGraphicsPixmapItem through keyboard

swapnilp96

I have a a character added via QgraphicsPixmapitem and now I want to move it by pressing the arrow keys on the keyboard. But I can't find a way. It gives compilation error. Help me please!

moveship.h (header file for my QPixmapItem)

    #ifndef MOVESHIP_H
    #define MOVESHIP_H
    #include <QGraphicsPixmapItem>

    class moveship: public QGraphicsPixmapItem
    {
        public:
        void keyPressEvent(QKeyEvent *event);
    };
    #endif // MOVESHIP_H

I am just checking if it recognises any key press or not.

Implementation of keyPressEvent:

  #include "moveship.h"
  #include <QDebug>

  void moveship::keyPressEvent(QKeyEvent *event)
  {
      qDebug() << "moved";
  }

My main source file:

    #include<QApplication>
    #include<QGraphicsScene>
    #include<QGraphicsView>
    #include<QGraphicsPixmapItem>
    #include <moveship.h>
    int main(int argc, char *argv[])
    {
        QApplication a(argc, argv);
        QGraphicsScene * scene = new QGraphicsScene();
        QGraphicsView * view = new QGraphicsView(scene);
    
        QPixmap q = QPixmap("://images/player.png");
        if(q.isNull())
        {
            printf("null\n");
        }
        else
        {
            moveship * player = new moveship(q);
            scene->addItem(player);
        }
    
        view->resize(500,500);
        view->show();
    
        return a.exec();
    }

Please help :(

Hi and welcome to devnet,

What exact error are you getting ?

Just saw that you already posted the same question here

Please, don't post the same questions multiple times in different sub forum. One is enough.

Closing it.
