[QtDesigner] passing a pointer from ui (QGraphicsView) as argument to another class constructor

LeB0ucEtMistere

Hello :)
As said, all is in the title, in my class generated by QtDesigner, i have a ui pointer with let me access all my ui elements. I have a QGraphicsView element and i want to sent a pointer onto to another class when i instantiate it in my main class. But it's like something is not going on .... I don't understand where the issue is...Here is the code :
@MainWindow::MainWindow(QWidget parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
_speed = ui->doubleSpinBox->value();
_iter = ui->spinBox_4->value();
_buttonState = 1;
int width = ui->graphicsView->width();
int height = ui->graphicsView->height();
QGraphicsView graph = this->getGraphicsView(); // here is the problem i think
_game = new( Logic(width,height,graph) ); // here is the line 15
}@

The log said : /Users/depassearthur/Documents/Programmation/ConwayGameOfLife-build-desktop-Qt_4_8_0_dans_le_PATH__Syst_me__Debug/../ConwayGameOfLife/mainwindow.cpp:15: erreur : expected type-specifier before ';' token

Here is the other parts of the code
my .h :
@#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>
#include <QGraphicsView>
#include "logic.h"

namespace Ui {
class MainWindow;
}

class MainWindow : public QMainWindow
{
Q_OBJECT

public:
explicit MainWindow(QWidget *parent = 0);
~MainWindow();

private slots:
void on_actionQuit_triggered();

void on_actionPreferences_triggered();

void on_actionA_Propos_triggered();

void on_actionEditer_le_mod_le_triggered();

void on_Launch_clicked();

private:
Ui::MainWindow *ui;

float _speed;
int _iter;
int _buttonState;
Logic *_game;
QGraphicsView* getGraphicsView();

};

#endif // MAINWINDOW_H
@

my function getGraphicsView() :
@QGraphicsView* MainWindow::getGraphicsView()
{
return ui->graphicsView;
}@

And the constructor of the other class ("logic")
@Logic::Logic(int width, int height, QGraphicsView* graph) :_iter(1),
_speed(1.0),
_width(width),
_height(height),
_graph (graph)
{
}
@

And its .h file

@
#ifndef LOGIC_H
#define LOGIC_H

#include <QGraphicsView>

class Logic
{
public:
Logic(int width, int height, QGraphicsView* graph);
void launch(int iter, float speed);
void setModel();
void stop();

private:
int _iter;
int _speed;
int _width;
int _height;
QGraphicsView* _graph;

};

#endif // LOGIC_H
@
If someone know why i have this strange error, i take it :) !
Thanks

welcome to devnet

My French is almost non-existent anymore. But if I understand your logic correct, it is not the line where you expect the trouble. The compiler is right.
Change to this:
@
_game = new Logic(width,height,graph); // here is the line 15
@

Hello :)
Thanks, what made you think i'm French ? (of course i am :p )
Thanks for your very fast answer, it is now good, the problem came from this point :) thanks

Hi,

Your paths, slot names and user name are in french and (AFAIK) there are not a lot of french speaking country that are represented here ;)

The language was a lucky guess ;-)
