getting data from a Dialog

[graciano]

Hi
I'm using public member-functions to get data from a called Dialog.

#ifndef A_H
#define A_H
 
#include <QtGui/QDialog>
 
namespace Ui {
    class a;
}
 
class a : public QDialog {
    Q_OBJECT
public:
    a(QWidget *parent = 0);
    ~a();
    QString getA();
protected:
    void changeEvent(QEvent *e);
private:
    Ui::a *m_ui;
};
 
#endif // A_H

#ifndef A_H
#define A_H

#include <QtGui/QDialog>

namespace Ui {
    class a;
}

class a : public QDialog {
    Q_OBJECT
public:
    a(QWidget *parent = 0);
    ~a();
    QString getA();
protected:
    void changeEvent(QEvent *e);
private:
    Ui::a *m_ui;
};

#endif // A_H

To copy to clipboard, switch view to plain text mode 

Calling the Dialog ...

void Dialog::calla()
{
    a x;
    x.exec();
    ui->a_lineEdit->setText(x.getA());
}

void Dialog::calla()
{
    a x;
    x.exec();
    ui->a_lineEdit->setText(x.getA());
}

To copy to clipboard, switch view to plain text mode 

Could someone point me other ways to do this!

Thanks
