Trying to set shortcut

[mikro]

hi,
i'd like to have shortcuts to change between the tabs of a tabwidget. after some searching through the fine manual and some posts i came up with:

page1 = new QAction(this);
page1->setShortcut(QKeySequence(tr("Ctrl+F1")));
connect(page1, SIGNAL(triggered()), this, SLOT(openPage1()));

page1 = new QAction(this);
page1->setShortcut(QKeySequence(tr("Ctrl+F1")));
connect(page1, SIGNAL(triggered()), this, SLOT(openPage1()));

To copy to clipboard, switch view to plain text mode 

which i hope will call

void MainWindow::openPage1() {
	tabWidget->setCurrentIndex(0);
}

void MainWindow::openPage1() {
	tabWidget->setCurrentIndex(0);
}

To copy to clipboard, switch view to plain text mode 

(and obviously two other, similar actions and functions for the other two tabs.

nothing happens. i also tried to set the translation to Strg+F1 in linguist as i am using the app in german. Where am i going wrong?
