access to widgets of statusbar

[navid]

hi

I added a qlabel to status bar in mainwindow constructor.
how can i change the text of the qlabel in another functions ?

QWidget *w = new QWidget();
    statusBar()->addWidget(w, 1);
    QLabel *l = new QLabel("Test Label");
    statusBar()->addWidget(l, 0);

QWidget *w = new QWidget();
    statusBar()->addWidget(w, 1);
    QLabel *l = new QLabel("Test Label");
    statusBar()->addWidget(l, 0);

To copy to clipboard, switch view to plain text mode 

regards
navid
