TabWidget index

[beppuz]

Hello,
I would like to know what the signal when I move between the tabs ....
Then if I create 5 tabs and I want to save into a variable my current position, i.e. the index of the tab in the foreground ... how do I? What is the method??

Thanks !!!!!!!

For everyone who don't want to change the forum: QTabWidget::currentChanged().

actually currentIndex() is a better solution since it does the job for you already.

Actually QTabWidget::currentIndex() is a property whereas QTabWidget::currentChanged() is the signal which notifies you about a tab change. That is the main question. Furthermore have a look at the argument of QTabWidget::currentChanged() ... you don't have to call QTabWidget::currentIndex() at all.

Implicit in the question is the actual need - the current index. since there is no need to use signal to store the value to check it later, currentIndex is the correct approach - any time you want to know the index, just check it! No need for connecting signals/slots. no need for storing a value that is already stored in the tab widget!!!

Asked for a signal.

Then if I create 5 tabs and I want to save into a variable my current position, i.e. the index of the tab in the foreground ... how do I? What is the method?QList<int> is also a variable and could be used for some sort of history. But neither you nor me can tell what the better solution is since we don't know what beppuz really wants.
