问题
I am using PyQt to make a GUI for a circuit simulator, and am programmatically creating and deleting tabs (i.e. the user clicks on a button, and a new tab is added to a QTabWidget).
This is already working (I drew a QFrame in Qt Creator and, in my code, add it as a new tab), but I need to refer to a widget which is inside a specific tab (e.g. a QwtPlot inside the 3rd tab). How can this be achieved?
回答1:
You can retrieve the widget from a specific tab by calling QTabWidget.widget(index).
