add a label in a QTabWidget

Hi,
I have a mainwindow and a QTabWidget in that window. The QTabWidget had 2 tab. I create this window using QT4.2.2 designet. Now I want add a lebel in tab 0 using code!!!. How can I do it?

Please don't double post. (link)

Well, the easiest way I think is just to add the label. Worry about layouts later:

Code:

---

QLabel *label = new QLabel("label");
tabWidget->insertTab( -1, label, "Tab Text");

---

That's about it.

Regards
