Dear all, I cannot manage to enable dropping data into an Item View class.
Basically: - The model is a custom QAbstractItemView subclass, having a tree structure. Column 1 is editable - The view is a standard QTreeView I would like to drop data from another widget in the editable field (column 1 indices). I have somewhere else in the app a custom widget that accepts the drop correctly using reimplemented dragEnterEvent and dropEvent, so the dragging is likely to be set up correctly. What I did on the view: - treeView->setAcceptDrops(true); - treeView->setDragDropMode(QAbstractItemView::DropOnly); - treeView->setDefaultDropAction(Qt::CopyAction); - treeView->setDragDropOverwriteMode(true); - treeView->setDropIndicatorShown(true); What I did on the model: - In the reimplemented flags(), I return for column 1 : Qt::ItemIsEditable | Qt::ItemIsDropEnabled | Qt::ItemIsEnabled | Qt::ItemIsSelectable. - I reimplemented setData, editing works. - I reimplemented dropMimeData. The mime type is "application/x-ocxml" but this function is likely not in cause since the drag cursor never shows an allowed drop - I reimplemented supportedDropActions, it returns Qt::CopyAction Then, the drag cursor never turns to the "drop allowed" indicator, and dropping always fails. I tried reimplementing mimeTypes to return QStringList("application/x-ocxml") but then the app crashes upon dragging. Any idea how to implement this? Thanks! Etienne
