Qt4/C++ - Accessing data on a QDialog form a QMainWindow

[jimbo]

Hello,

I'm constructing multiple QDialogs from a button on a QMainWindow.
Each dialog gets filled with different data when constructed and I (may) edit this data.
I can find which dialogs have been edited and get the dialogs objectName when I click
the qmainwindow 'save' button.
Is it possible to access, say a QLabel->text() on one of the dialogs only knowing the dialogs objectName?
If 'yes, how?
Perhaps I should adopt a different approach.

Regards

class propForm : public QDialog
{
    Q_OBJECT
 
public:
    propForm(QWidget *parent = 0);
    ...
 
propForm::propForm(QWidget *parent) : QDialog(parent)
{
    ...

class propForm : public QDialog
{
    Q_OBJECT

public:
    propForm(QWidget *parent = 0);
    ...

propForm::propForm(QWidget *parent) : QDialog(parent)
{
    ...
