access to class functions/members in QTabWidget

[ithinkso]

Hi,

In my program i have class like this:

class WorkingTab : public QWidget

class WorkingTab : public QWidget

To copy to clipboard, switch view to plain text mode 

and QTabWidget in a mainwindow where i'm adding WorkingTab into tabs

WorkingTab *newtab = new WorkingTab;
    tab_widget->addTab(newtab,"something")

WorkingTab *newtab = new WorkingTab;
    tab_widget->addTab(newtab,"something")

To copy to clipboard, switch view to plain text mode 

And my question is...how can i access to WorkingTab class public functions/members via QTabWidget? I have no idea, QTabWidget::widget(int) returning only QWidget...i need my own WorkingTab class.

regards
