QTabWidget and current tabs

[Todd Widup]

I am using currentWidget to get the current tab, but it doesnt work 100% correctly for me

ie : i have 3 tabs, Root, Arm, Leg

if I select leg, it will print leg.  if I select arm, it will print leg, and if I select arm again, it will print arm this time. 

very first selection will print correctly, the rest are always 1 selection behind

Are you connecting to QTabWidget.currentChanged() signal to respond and print the currentWidget() value? If so, can you see if it makes a difference if you do your connection like this:

tabWidget.currentChanged.connect(self.someSlot, QtCore.Qt.QueuedConnection)

Similar threads have reported a lag in the event loop updating things, so I wonder if waiting until the event loop runs before evaluating your slot would make a difference.

Interesting. One would think that if the signal is firing, that the state of the QTabWidget should now be accurate. I guess use that approach as-needed when you see this kind of lag in the state :-)
