Buttons

Hello,

i have read few forum on it but i need your help for a little problem :

i want to put a button on my window,
i declared my button on the main with :
QPushButton *bouton = new QPushButton("Connecter",ui->pushButton);
bouton->setCheckable(true);

i would like to make an action named "connection" when i click on it. So i connect the button but i don't know what i should write instead of the "???"
connect(ui->pushButton,SIGNAL(clicked()),????,SLOT(connection ()));

should i create a new file to put my function into?

Thanks

first you have to declare connection() as a slot. second, it does not matter where (in which class) you declare that slot, just put a pointer to that class instead of ?????.
Most likely, you declare that slot in the widget you create your button, then use this for ???.

1. Is it that you really wanted to put new buttun bouton INSIDE another button ui->pushButton ?
2. If you have a QAction, named connection, you should do

Code:

---

connect(ui->pushButton,SIGNAL(clicked
()),ui-> connection,SLOT(trigger()));

---

thanks, but i still have a problem ^^

i declared my function connection as a slot like that in my header :
class MainWindow : public QMainWindow
{
Q_OBJECT
....
public slots :
void connection();
...
};

in the .cpp i write that :
QPushButton *bouton = new QPushButton("Connecter Wiimote",ui->pushButton);
bouton->setCheckable(true);
QObject::connect(ui->pushButton,SIGNAL(clicked()),this,SLOT(connection ()));

my function connection is :
void MainWindow::connection()
{
...
}

There is no errors at the compilation.
However when i cllick on the button, the code in my function connection is not executed... what's wrong?

emmm)
Write this and all will earn:

Code:

---

QObject:: connect (bouton, SIGNAL (clicked(), this, SLOT (connection ()));

---

cool! i'm a joke... ^^
Thanks :D

if you use ui you don't have to create a new button. ui->pushButton is already a full button, so there is no need to recreate one. Simply use your

Code:

---

QObject::connect(ui->pushButton,SIGNAL(clicked()),this,SLOT(connection()));

---

and skip all the

Code:

---

QPushButton *bouton = new QPushButton("Connecter Wiimote",ui->pushButton);
bouton->setCheckable(true);

---

things...

Lykurg you are right, but its way is amusing and works)
valy12 when you add object in gui redactor, it is not obligatory to describe again the button in a code, the nobility its objective name suffices and to address to it it is possible through the index ui)
