Drag and Drop item inside QTreeWidget

[nina1983]

Dear,

I'm new with Qt, it's one day that I'm trying to solve this problem...
I want to be able to drag and drop elements inside my QTreeWidget but I want that the hierarchy is respected... here an example:

QTreeWidget* tree = new QTreeWidget(QDialog);
tree->setAcceptDrops(true);
tree->setDragEnabled(true);
tree->setDragDropMode(QAbstractItemView::InternalMove);
 
QTreeWidgetItem* dad = new QTreeWidgetItem(tree,0);
 
QTreeWidgetItem*  child = new QTreeWidgetItem(dad,0);

QTreeWidget* tree = new QTreeWidget(QDialog);
tree->setAcceptDrops(true);
tree->setDragEnabled(true);
tree->setDragDropMode(QAbstractItemView::InternalMove);
	
QTreeWidgetItem* dad = new QTreeWidgetItem(tree,0);

QTreeWidgetItem*  child = new QTreeWidgetItem(dad,0);

To copy to clipboard, switch view to plain text mode 

I want to be able to drag and drop only "dad" elements (with its childs attahced obviously) at the same level as the other "dad" elements...
I hope you can understand my problem... if not please let me know and I'll try to explain it better!
Thank you very much

Lisa
