Layout objects reusable?

[alitoh]

I was wondering if it was possible to use same layout objects (a QHBoxLayout, i.e) to define the layout of different objects.

E.g.

QHBoxLayout * boxLayout;
QGridLayout * gridLayout;
 
QGroupBox * group1;
QGroupBox * group2;
QGroupBox * group3;
 
QComboBox * comboBox1;
QComboBox * comboBox2;
QComboBox * comboBox3;
 
QLabel * label1;
QLabel * label2;
QLabel * label3;
 
//-------------------
 
 gridLayout->addWidget(label1);
 gridLayout->addWidget(comboBox1);
 
groupBox->setLayout(gridLayout);

QHBoxLayout * boxLayout;
QGridLayout * gridLayout;

QGroupBox * group1;
QGroupBox * group2;
QGroupBox * group3;

QComboBox * comboBox1;
QComboBox * comboBox2;
QComboBox * comboBox3;

QLabel * label1;
QLabel * label2;
QLabel * label3;

//-------------------

 gridLayout->addWidget(label1);
 gridLayout->addWidget(comboBox1);

groupBox->setLayout(gridLayout);

To copy to clipboard, switch view to plain text mode 

and then do somethingl ike gridLayout->clear(); and reuse that layout.

My problem is that I've found myself in need of nested layouts inside 3 GroupBoxes and it would be rather annoying to triple the ammount of objects (once for every GroupBox) just because of it.

Thanks for your help.
