QListWidget reorder with Drag and Drop

[goetz]

Do you use a user interface made with Qt Designer and did you change some of the drag/drop settings there?

Do you use QListWidget or QListWidget inherited widget? If you inherit from listWidget and use mouse or drag events and didn't pass event to QListWidget, drag and drop will not work.

I made it with Qt Designer and I changed the drag and drop properties a lot, but now I changed them back to just dragDropMode = internalMove and put the others back to default. The selection mode is ExtendedSelection, but I tried the default, too.

[goetz]

That should work. I tried this with designer and could move the items in the preview mode (Ctrl-R/Cmd-R). That should work in the real code too, if you do not change other drag/drop settings there too.

Even stranger news:

I created a new project, copied and pasted all of the code / widgets, and now its working!

Any ideas why this happened and how to prevent it in the future?

Sorry, I do not have any clue what's happening there. Maybe some alien code from outer space? :-)

Here is my scenario: You use visual studio. Your code had little error. Complier didn't compile code and ran old executable.

Actually, I use Qt Creator.

The viewMode should be ListMode(default) but not IconMode, even items have icons.
