Muti Selection in PyQt6?

bebewinla

I have these following which work in PyQt5 for QtTreeWidget
self.setSelectionMode(self.ExtendedSelection)
self.sortByColumn(1,Qt.Qt.AscendingOrder)

Are those obsolete in PyQt6? What should I use for replacements.

Don't know. You did not say what the problem is...

Both of the methods are just as available in [Py]Qt6 as they were in [Py]Qt5. [Though PySide6 does not seem to document QTreeWidget.setSelectionModel(), but I don't see why it should not be there.]

However, I see these two statements each pass a Qt enumerated type value (self.ExtendedSelection, Qt.Qt.AscendingOrder). Could it be on those tokens that you are getting an error message? ISTR that at PyQt6/PySide6 such enum values which were in the global Qt namespace have been moved down into a more specific namespace. So Qt.AscendingOrder needs to become something like Qt.SortOrder.AscendingOrder. I don't know where you look up what these got changed to, and I am not even sure that the PySide6 documentation tells you, but you have to find out somehow....

I got this error :
self.setSelectionMode(self.ExtendedSelection)
AttributeError: 'Table' object has no attribute 'ExtendedSelection'

where Table is a QtTreeWidget.
So I tried the following:
self.setSelectionMode(self.selectionMode.MultiSelection)
and it doesn't like it either. See error below

self.setSelectionMode(self.selectionMode.MultiSelection)
AttributeError: 'builtin_function_or_method' object has no attribute 'MultiSelection'

As I suggested, the enumerated type namespaces have changed, you need to use the correct ones in PyQt6.

Also I don't think it's usual to access a enumerated value via self, e.g. like self.ExtendedSelection, I don't know whether Python allows this.
