Constructor & Destructor Documentation
◆ DragDropModelImplementation()
| Digikam::DragDropModelImplementation::DragDropModelImplementation | ( | ) |
A class providing a sample implementation for a QAbstractItemModel redirecting drag-and-drop support to a handler. Include the macro DECLARE_Model_DRAG_DROP_METHODS in your derived QAbstractItemModel class.
◆ ~DragDropModelImplementation()

Member Function Documentation
◆ dragDropFlags()
|
virtual |
Call from your flags() method, adding the relevant drag drop flags. Default implementation enables both drag and drop on the index if a drag drop handler is set. Reimplement to fine-tune. Note: There is an alternative below.

◆ dragDropFlagsV2()
| Qt::ItemFlags Digikam::DragDropModelImplementation::dragDropFlagsV2 | ( | const QModelIndex & | index | ) | const |
This is an alternative approach to dragDropFlags(). dragDropFlagsV2 calls the virtual methods isDragEnabled() and isDropEnabled() which you then reimplement. Use simple dragDropFlags() if you need not customization, or reimplement dragDropFlags() if you fine-tune it yourself.

Set a drag drop handler.

Referenced by Digikam::DigikamItemView::DigikamItemView(), and Digikam::ImportIconView::ImportIconView().
◆ supportedDropActions()
| Qt::DropActions Digikam::DragDropModelImplementation::supportedDropActions | ( | ) | const |
Implements the relevant QAbstractItemModel methods for drag and drop. All functionality is redirected to the handler. dropMimeData() always returns false, leaving implementation to the view.
