problem in adding toolbar

[bhogasena]

hi,
i have derived one class from QWidget. in derived class i add QGlwidget in that irendered some objects. now i would like to add toolbar to the widget.

in derived class i declare objects for QAction and QToolbar

i have written code like
code:

void Window::createToolBars()
{
    zoomToolBar = addToolBar(tr("Zoom"));
    zoomToolBar->addAction(zoominAct);
 
    zoomToolBar->addAction(zoomoutAct);
 
    zoomToolBar->addAction(resetAct);
 
    mouseToolBar = addToolBar(tr("Mouse"));
    mouseToolBar->addAction(mouseAct);
 
}

void Window::createToolBars()
{
    zoomToolBar = addToolBar(tr("Zoom"));
    zoomToolBar->addAction(zoominAct);

    zoomToolBar->addAction(zoomoutAct);

    zoomToolBar->addAction(resetAct);

    mouseToolBar = addToolBar(tr("Mouse"));
    mouseToolBar->addAction(mouseAct);
    
}

To copy to clipboard, switch view to plain text mode 

it showing error as "addToolBar" is undeclared identifier.
can any one help me so that i'll be thankful to you.

thanks and regards
