How to prevent a closing tab QTabWidget? PyQT4

With this code:

QtCore.QObject.connect(self.tabWidget, QtCore.SIGNAL("tabCloseRequested(int)"),
                       self.tabWidget.removeTab)

I can close any tab QTabWidget, and the names of these tabs are:

work_1

work_2

work_3

But I want the tab work_1 never closes.

Use Index did not work for two reasons:

The tabs can be dynamically moved by this code:
```
self.tabWidget.setMovable (True)
```

That makes the Index are constantly changing.

The user has the ability to add new tabs.

Solution

Tabs can be identified by their widgets, and the widgets can be identified by their objectName (or some other unique attribute):

        self.tabWidget.tabCloseRequested.connect(sef.removeTab)
        ...

    def removeTab(self, index):
        widget = self.tabWidget.widget(index)
        if widget is not None and widget.objectName() != 'work_1':
            self.tabWidget.removeTab(index)

or perhaps more simply:

        if widget is not None and widget is not self.work_1:
            self.tabWidget.removeTab(index)
