QSignalMapper not working.

[A Former User]

Hi, i use QSignalMapper like this:
@
class MainWindow;
}

class MainWindow : public QMainWindow
{
Q_OBJECT

public:
explicit MainWindow(QWidget *parent = 0);
~MainWindow();
public slots:
void cclick(int);

private:
Ui::MainWindow *ui;
QSignalMapper *signalmaper;
};@
in constructor:
@
signalmaper = new QSignalMapper(this);
connect(signalmaper, SIGNAL(mapped(int)),this,SLOT(cclick(int)));
ui->setupUi(this);
signalmaper->setMapping(ui->pushButton,10);
@

@void MainWindow::cclick(int x)
{

ui->pushButton->setText("dfdff");

}
@
but when i click on button nothing happen. any idea?

Hi,

Did you check that the slot was called ? With i.e the debugger or simply a

@qDebug() << Q_FUNC_INFO;@

in cclick ?

What's the original text of pushButton ?

the slot not called. this is application output:
@

You are missing a connect statement:
@
connect(ui->pushButton, SIGNAL(clicked()),signalmaper,SLOT(map()));
