ListWidgetItem editItem does not work
Message 1 in thread
Hello,
in a QListWidget I have some Items and want to edit them.
I thought that this would do the trick:
QListWidget * listSubjects = new QListWidget();
QListWidgetItem * lwI = new QListWidgetItem();
lwI = listSubjects->currentItem();
lwI->setFlags(Qt::ItemIsEditable);
i = lwI->flags();
listSubjects->editItem(lwI);
But the application just writes "edit failed" to the console.
What did I miss?

I think you forgot to mention the parent of the QListWidgetItem instance i.e.,
you declared the instance but didn't set it in the QListWidget
Also curentItem() returns the QListWidgetItem belonging to the current
QListWidget, and not set the set item into the listWidget.
use
QListWidgetItem * lwI = new QListWidgetItem(listSubjects, type);
>
to specify the parent while making the declaration, or use
listSubjects->insertItem(row, lwl);
>
after you have the set the flags as you desire.
Hope it should work :)

Hello,
yes thanks for the hints. It helped a lot. Furthermore I changed the setting
of the flags to
lwI->setFlags(lwI->flags() | Qt::ItemIsEditable);
which I found in the designer code but not in the examples or in the docs.
Now it works just perfect :))

Where do you assign the ListWidgetItem to the ListWidget?
