Mouse click events for QPixmapItem objects



  • Hi everyone,

    I'm playing around with Qt to get a grip of its basics, and can't seem to do it very well.

    Here's a few lines of my code:

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

        QGraphicsScene scene;
        QGraphicsView view(&scene);
        QGraphicsPixmapItem item(QPixmap("C:\\card set\\s8.gif")),
                item2(QPixmap("C:\\card set\\s9.gif"));
        scene.addItem(&item), scene.addItem(&item2);
       view.show();
      return app.exec();
    

    }@

    How do I go about adding click events for these objects?
    Is there a more efficient way to declare and add items?

    I checked the documentation, but it still seems a bit confusing.

    I'd like to get quite a thorough explanation. Sorry if it seems noobish, but..I am very new to this.

    Thank you!

    You can subclass QGraphicsView, implement mousePressEvent and use itemAt() like shown in "this example":http://qt-project.org/doc/qt-5/qgraphicsview.html#itemAt

    As for more info on how to use graphics view you can look at "these examples":http://qt-project.org/doc/qt-5/examples-graphicsview.html
