Bug in Qt 5.12 drag n'drop ?
-
Please provide a example - otherwise I don't see how we can spot the problem...

https://sourceforge.net/projects/skylendar/
and compile it with qt5.12.0
When compiled and running, drag the "Now" Dataset (on the left column) onto the window named "Standard wheel".Then, the pointer becomes a barred red circle, instead of a black hand for dropping, i.e. dropping is impossible.
When compiled with 5.11 apparently nothing happens because the standard wheel already uses "Now", but it works...

I tried to run your app but I won't let something run as root on my system. Please provide a minimal, compilable example to reproduce the issue.

probably the elevated rights are part of the problem?

Don't think so - it's using a database and the app which creates the schema etc. wants admin rights. After this it looks like the normal application can run without admin rights but did not came that far.

If you really are scared to run skydmin as root, I can tell you how to install the db as the postgres non-root user.
@skylendar Thanks, but I don't think I'll debug your program ;)
I have too much of my own problems

@skylendar thats why we need a simple program, trimmed down to the actual problem.
Otherwise its hard to track down where the bug is. Until now it is not even proven that Qt is guilty.

And you forget something: Qt is actually a commercial program, and most of you, if not all, are paid for debugging it. Why should I work for you for free ?

Actually this is a user forums and no one here is paid anything to help :)
We are not employees, but ordinary users of Qt.Anyway, i tried some of old drag drop sample with Qt 5.12 and
they seems to work. At least on windows. -

If you happen to own a commercial license you should contact the customer support they may be able to help you more directly.
However they also will ask for a minimal compileable project, if your current project is considerably too large.
Alternatively there is also the option of paid consulting either from the QtCompany directly or other companies, like for example KDAB -

Hi
What about test with the sample that comes with Qt ?
http://doc.qt.io/qt-5/dnd.html#examples
There are often directly available in Creator. -

Found the puzzle in the examples. It works, but in my case the draggable widget is placed in a QTreeWidget, not just an ordinary QWidget.
Hi
well it its almost the same unless you used
QStandardItemModel::dropMimeData()
or something like that. -

Everything seems ok, but the dropEvent() method of my QWidget isn't activated (setAcceptDrop() is set to true, of course)

Check the

as it drops from ListWidget to Widget.
