RE: How to make drag&drop in QListView

Hello,

You have to set this parameters :

setDragEnabled(true);
setAcceptDrops(true);


You should also set your items enabled for drag&drop

yourItem->setFlags(Qt::ItemIsSelectable | Qt::ItemIsEnabled | Qt::ItemIsDragEnabled | Qt::ItemIsDropEnabled)


With those parameters, it should be cool :)

Yes, it's Qt4 code... your project is made with Qt3 ?

Yes but now im porting it to QT4... And this code will be enough to make Drag'n'Drop? Or i'll have to write some slots?

You have to implement handlers which will be executed when an item is dropped. See docs for details and examples.

I've decided to make drag and drop in QTreeWidget... What do i need to do to implement Drag'n'Drop inside the treewidget (i need it only to change items order). Any sugestion? I dont know if im right, but i think i should promote it to custom widget and reimplement itemPressed slot, add mouseMoveEvent... Correct me if im wrong

EDIT:
I've enabled draging and droping at widget, and drag'n'drop works but it copy draged items. Also i want to disable childs to all items.

EDIT:
I've made items with no childs by setting the identation to 0... the only problem is the copying now... Anyone knows where to set default drop action?
