How to get item after drag item from QListWidget Thumbnails

[VRonin]

onThumbItemClicked

Do you want to respond to a click or to a drag?

[amarism]

@VRonin on drag bcz onClick is working fine for me.

[VRonin]

And do you want to know it as soon as the item is dragged or when it gets dropped somewhere else?

[amarism]

@VRonin when item is drag from listWidget

[VRonin]

then you need to reimplement void startDrag(Qt::DropActions supportedActions) with:

void startDrag(Qt::DropActions supportedActions){
QTableWidget::startDrag(supportedActions);
QModelIndexList indexes = selectionModel()->selectedIndexes();
    auto isNotDragEnabled = [this](const QModelIndex &index) {
        return !(model()->flags(index) & Qt::ItemIsDragEnabled);
    };
    indexes.erase(std::remove_if(indexes.begin(), indexes.end(),
                                 isNotDragEnabled),
                  indexes.end());
QVector<QListWidgetItem*> draggetItems;
draggetItems.reserve(indexes.size());
for(auto& index : qAsConst(indexes))
draggetItems << itemAt(index.row()));
// now draggetItems contains the list of dragged items

@VRonin said in How to get item after drag item from QListWidget Thumbnails:

QModelIndexList indexes = selectedIndexes();

Its showing selectIndex() is undefined.

I m added this one code for startDrag:-

void GLWidgetdrag::startDrag(Qt::DropActions supportedActions)
{
QListWidgetItem* item = currentItem();
QMimeData* mimeData = new QMimeData;
QByteArray ba;
ba = item->text().toLatin1().data();
mimeData->setData("application/x-item", ba);
QDrag* drag = new QDrag(this);
drag->setMimeData(mimeData);
if (drag->exec(Qt::MoveAction) == Qt::MoveAction) {
	/*delete takeItem(row(item));
	emit itemDroped();*/
}
}

Still Here showing this one error " QListWidgetItem* item = currentItem(); "

[VRonin]

Its showing selectIndex() is undefined.

yes, sorry, I forgot 1 call, it's selectionModel()->selectedIndexes(), corrected now. I have no idea what you are trying to do in your implementation

@VRonin Again its showing error:

[VRonin]

That method should go in a subclass of QListWidget

@VRonin said in How to get item after drag item from QListWidget Thumbnails:

auto isNotDragEnabled = [this](const QModelIndex &index) {
return !isIndexDragEnabled(index);
};

showing error in this line " !isIndexDragEnabled(index) "

[VRonin]

Yep, sorry, corrected now

[amarism]

@VRonin Now i m getting this one error "ErrorC3867 'QModelIndex::row': non-standard syntax; use '&' to create a pointer to member" In this line " draggetItems << itemAt(index.row)); "

[VRonin]

These are just typos that are easy to fix... c'mon. I just forgot (). index.row should be index.row()
