how to program custom Dialogs with return values

Hi,
I wonder how to write modal Dialogs executed with QDialog::exec(), that provide a result other than integer values ( which can be easily achieved with QDialog::accept(), QDialog::reject() and QDialog::setResult() ). Since there are Dialogs that return objects like QFonts, QColors etc. all over Qt4, I guess there must be a (simple) mechanism to do that. Any Ideas?

thanx in advance

Yes, but they either use static methods or signals.

Of course you can always do something like this:

Code:

---

class MyDialog : public QDialog {
public:
 // ...
  QString myExec(){
    if(exec())
      return myresult();
    else return ""; 
  }
private:
  QString myresult() const { return ... }
};

---

and call it using

Code:

---

MyDialog dlg;
QString r = dlg.myExec();
