Connecting from a dialog to mainWindow

[anda_skoa]

You can forward the signal from the Dialog's line edit

class Dialog : public QDialog
{
    Q_OBJECT
public:
    explicit Dialog(QWidget *parent = 0);
 
signals:
    void textChanged(const QString &text);
};

class Dialog : public QDialog
{
    Q_OBJECT
public:
    explicit Dialog(QWidget *parent = 0);

signals:
    void textChanged(const QString &text);
};

To copy to clipboard, switch view to plain text mode 

Dialog::Dialog(QWidget *parent)
    : QDialog(parent)
    , ui(....)
{
    connect(ui->lineEdit, SIGNAL(textChanged(QString)), this, SIGNAL(textChanged(QString)));
}

Dialog::Dialog(QWidget *parent)
    : QDialog(parent)
    , ui(....)
{
    connect(ui->lineEdit, SIGNAL(textChanged(QString)), this, SIGNAL(textChanged(QString)));
}

To copy to clipboard, switch view to plain text mode 

And then connect that signal in your main window to whatever slot you want.
