Drag-drop with internalmove makes items disappear
-
Hi,
I'm trying to make drag and drop inside a treewidget work to be able to move items around. I've managed to make items draggable but when I release the mouse button the item disappears. I've tried the following example from stackoverflow and this has the same issues as my tree widget in Qt 5.4 on Windows 7.
#include <QListWidget> int main(int argc, char **argv) { QApplication a(argc, argv); QListWidget lw; for(int i = 1; i < 10; ++i) lw.addItem(new QListWidgetItem(QString("Item %1").arg(i))); lw.setDragEnabled(true); // *** lw.viewport()->setAcceptDrops(true); // *** lw.setDefaultDropAction(Qt::MoveAction); // *** lw.setDropIndicatorShown(true); // *** lw.setDragDropMode(QAbstractItemView::InternalMove); lw.show(); a.connect(&a, SIGNAL(lastWindowClosed()), &a, SLOT(quit())); a.exec(); }
Here's how this looks for me:
Any ideas?

Hi and welcome to devnet,
Can you try again with Qt 5.5 ?

tried the code with 5.5 and it does work there.
