Qt 5.12 to 5.15 => Drag&Drop problems

Poupzo

Hey,
I have a working project in version 5.12 that I'm trying to upgrade to 5.15.

The problems are that drag and drop doesn't work the way it used to and I can't find any info in the patch notes I have access to.

I've got too many problems so I can't explain all of them, so if you just have some information on whether anything has changed between these versions here I'll thank you for it.

Have a good day!

If you don't say what is not working and what "many problems" are, nobody can help you.

What I was basically asking was whether there had been any changes between the different versions because I have different behaviors between them.

But for example, the kind of problem I'm having is that there are different QListWidgetItems and some of them don't drop into the zone they should, while others still do.
Still for drag and drop with lists, when I drag an item to reorder it and drop it on itself, it throws the "RowsRemoved" event, which deletes my item and throws my empty but existing row.

@Poupzo Hi,

If you haven't found anything in the release notes, then I would check the git history of the files concerning the class you are using both the views and the models.

Several bugs are solved in 5.15.14 like that : https://bugreports.qt.io/browse/QTBUG-100128

For the moment I cannot have this version so to others like me you can find a workaround here : https://stackoverflow.com/questions/74263946/widget-inside-qlistwidgetitem-disappears-after-internal-move

@Poupzo Since you would need to build Qt anyway to use that version, you can take the current latest and apply the patch linked to the bug report.
