QTreeWidget - multiple columns d&d

[Sorin]

I have a QTreeWidget with tree columns:

@void MyTree::AddNewElement()
{
QTreeWidgetItem* treeItem = new QTreeWidgetItem( this, 0 );
treeItem->setText( 0, "someText" );
setItemWidget( treeItem, 1, new QToolButton( this ) );
setItemWidget( treeItem, 2, new QToolButton( this ) );
}@

for this widget I want to implement d&d so all the columns should keep their content. Right now when I'm d&d only the text column keeps the content. How should I do it right?

Thanks!

Drag'n'drop for item widgets is not supported out of the box.

You would have to go with QTreeView and a customized model to make this work.

yes you're right about this, I need to do some more studying :) , I found a nice example "here":http://www.java2s.com/Code/Cpp/Qt/QTreeViewdraganddrop.htm

Does setting the following work?
@
MyTree::MyTree(...)
{
setDragEnabled(true);
setAcceptDrops(true);
setDragDropMode(QAbstractItemView::InternalMove);

...
}

Looking at the source code of the Qt libs, the widgets (resp. their pointers) plainly don't make their way into the dragged data.
