[Solved] Signal/slot doesn’t work

[silep]

Hello,

I am practicing Qt5 and I tried some easy signal/slots which worked, but now I tried to open a Dialogwindow with a connect and it doesn't work. I really don't know why.. I tried to open only the window in the main and it worked, so the problem comes probably from the connect line.

MaFenetre.h

@class MaFenetre: public QWidget
{
public:
MaFenetre();
~MaFenetre();
void show();

public slots:
void OuvrirDialogueQuestion();

private:
QWidget *cadre;
QPushButton *bouton2;
};@

MaFenetre.cpp

@MaFenetre::MaFenetre()
{
cadre = new QWidget;
cadre->setFixedSize(1905,1005);

bouton2 = new QPushButton("Question!",cadre);
bouton2->setFont(QFont("Lucida Handwriting",20));
bouton2->move(300,900);
QObject::connect(bouton2, SIGNAL(clicked()), this , SLOT(OuvrirDialogueQuestion()));

MaFenetre::~MaFenetre()
{
delete bouton1;
delete bouton2;
delete lcd;
delete slider1;
delete slider2;
delete barre;
delete cadre;
}

void MaFenetre::show()
{
cadre->show();
}

void MaFenetre::OuvrirDialogueQuestion()
{
QMessageBox::question(this,"Question","Est ce que tu aimes les nems?", QMessageBox::Yes | QMessageBox::No);
}@

main.h

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

QApplication app(argc, argv);
MaFenetre window;
window.show();

return app.exec();
}@

Would anyone have an idea about where the error could be? If you have any advice about this program, I would be interested to read them too. Thank you in advance!

Oups sorry I am not in the good topic folder, but I don't know how to delete my topic

You need a Q_OBJECT designation in your class declaration.
@
class MaFenetre: public QWidget
{
Q_OBJECT
public:
MaFenetre();
~MaFenetre();
void show();

public slots:
void OuvrirDialogueQuestion();

private:
QWidget *cadre;
QPushButton *bouton2;
};

Be sure and add a Q_OBJECT macro in your class. You may need to run qmake again, too.

[Edit: Oops, didn't see mranger90's response.]
