Can't set tab order after rearranging widgets

[JTHundley]

I have a verticalLayout in a scrollArea that I add custom widgets to. When I do this, the tab order is properly set. I then have radioButtons to change the order and sort these widgets. I've tried about 4 different ways to change the tab order to respect this new ordering, but every time it's ignored. I have a feeling I might be doing something more fundamentally wrong somewhere else, like in the way I re-order these custom widgets.

Here's the section in question, cards is a list of the custom widget:

    def _sort_cards(self, cards: list) -> 
        "Helper method to sort cards into the scrollarea. cards is the sorted list of Card objects to use."
        print("_sort_cards")
        # add all the cards and show the line:
        for card in reversed(cards):
            self.verticalLayout_player_cards.insertWidget(0, card)
            card.show_line()
        # set tab order:
        last_card = None
        for card in 
            if last_card:
                self.setTabOrder(last_card, card)
                print("setTabOrder:", last_card, card)
            last_card = card
        self._hide_top_card_line()

The full code is here and I can also share the whole project if it's helpful: https://0x0.st/XDHU.bin

I'm new to the forums and have been eagerly using and learning qt for a little bit now :) Thanks in advance!

You usually don't do this.
It's counterproductive in a QScrollArea and might break the scroll functionality.
Use QScrollArea::setWidget to add your large, scrollable widget (with layout) instead.

Haven't looked at your code, but when doing the above correctly,

every time it's ignored

this might work then.

Thanks for your response, but I'm not sure I understand. The scrolling actually does work fine the way it is, but I removed the verticalLayout from the scrollArea and found that it all works the same. Sorting and scrolling still work, but when rearranging the widgets within the scrollArea the tab order remains the way it was when the widgets were first added.

Hi,

You need to use setTabOrder after you moved your widgets around.

[JTHundley]

@SGaist Like I did in the code snippet? Or did I do it wrong? I've used setTabOrder successfully before which is why I'm so confused.

[SGaist]

Sorry, I somehow did not see it.
However, your loop code seems broken or is it a copy paste error ?

That said, you could use the Python zip function to create the pairs of widgets. The first list being the original minus the last one and the second list the original with the first item removed.

[JTHundley]

@SGaist Yes, that was a paste error, "for card in cards:" :)

So basically you're saying I should delete the widgets and recreate them so they can be freshly inserted or added into the scrollArea, right? This is my latest attempt that I'm trying, mixed results so far.

Can you explain more in details. Because i understand your words.
