    Smile QGraphicsscene and QGraphicsview

    Hey guys,
    my Code:
    Qt Code:
    1. #include "../header/analyse.h"
    2. #include "ui_analyse.h"
    3. #include <QDebug>
    4.  
    5. Analyse::Analyse(QWidget *parent) :
    6. QWidget(parent),
    7. ui(new Ui::Analyse)
    8. {
    9.  
    10. ui->setupUi(this);
    11.  
    12. scene = new QGraphicsScene();
    13. this->ui->graphicsView->setScene(scene);
    14. this->ui->graphicsView->setRenderHint(QPainter::Antialiasing);
    15.  
    16. }
    17.  
    18. Analyse::~Analyse()
    19. {
    20. delete ui;
    21. }
    To copy to clipboard, switch view to plain text mode 
    Qt Code:
    1. #ifndef ANALYSE_H
    2. #define ANALYSE_H
    3.  
    4. #include <QWidget>
    5. #include <QPushButton>
    6. #include <QGraphicsLineItem>
    7. #include <QStringList>
    8. namespace Ui {
    9. class Analyse;
    10. }
    11.  
    12. class Analyse : public QWidget
    13. {
    14. Q_OBJECT
    15. public:
    16. explicit Analyse(QWidget *parent = 0);
    17. ~Analyse();
    18. private:
    19. Ui::Analyse *ui;
    20. };
    21. #endif // ANALYSE_H
    To copy to clipboard, switch view to plain text mode 
    The user can add moveable Items to the scene. I want that you can only move Items through the right border. I got two problems:
    The borders one the left, top and bottom site. If you try to move an item through this borders it stops.(colide)
    If you move items to the right border of the scene scroll bars should appear. and the scene should extend.
    A scene like this :
