giving value to int in other class from mainwindow.cpp



  • Hello. there.. I want to change variable value from mainwindow.cpp (mainwindow.h) to scene.h..
    So that i can do some logic in scene.cpp... by checking variable value;
    variable is int test;

    I have mainwindow.h which look like this
    #ifndef MAINWINDOW_H
    #define MAINWINDOW_H
    #include "scene.h"

    namespace Ui {
    class MainWindow;
    }

    class MainWindow : public QMainWindow
    {
    Q_OBJECT

    public:
    explicit MainWindow(QWidget *parent = 0);
    QList<QString> clickedData;
    ~MainWindow();

    private slots:
    void on_pushButtonChange_clicked();

    private:
    Ui::MainWindow *ui;
    QGraphicsView *view; //just pointers
    QGraphicsItem *item;
    QGraphicsScene scene;
    QAction
    selectAction;
    };

    #endif // MAINWINDOW_H
    Now so if I click on on_pushButtonChange then it should give variable a value in other class called Scene

    so scene.h is like this
    #include <QGraphicsScene>
    #include <QGraphicsSceneMouseEvent>
    #include <QGraphicsView>

    class Scene : public QGraphicsScene //inherit
    {
    public:
    Scene(QObject* parent = 0); //construct.
    int test; //this should be changed so that I can do some logics
    protected:
    void mousePressEvent(QGraphicsSceneMouseEvent *event;
    };

    #endif // SCENE_H

    Thanks for help.

    Hi,

    Where do you have an instance of Scene ?
