PyQt4 close tab that request closing - tabs

Question

I cannot find a way to close the tab that request to be closed. I only found how to close current widget and current tab. Any ideas? I can't find a clue on internet.
self.tabs.tabCloseRequested.connect(self.removeTab)
def removeTab(self):
tab = self.tabs.currentWidget()
tab.deleteLater()

Answer 1

The QTabWidget class has a removeTab method, which will remove a tab, but without deleting its content widget. So you will also need to delete the content widget explicitly:
self.tabs.tabCloseRequested.connect(self.removeTab)
...
def removeTab(self, index):
widget = self.tabs.widget(index)
if widget is not None:
widget.deleteLater()
self.tabs.removeTab(index)

I can post you the code, but it's a bit confused.
