Get position of widget under cursor during drag and drop in a QTreeWidget

[gabello306]

I am performing a drag and drop from a QListWidget to a QTreeWidget. Using the following code I can get a position during the mouse movement but the QToolTip::showText seems to be displayed in Global coordinates instead of coordinates inside the QTreeWidget.

        // Drag move event
        QDragMoveEvent *moveEvent = static_cast<QDragMoveEvent *>( event );
            
        QTreeWidgetItem *hoveredItem =
                timingTree->itemAt( moveEvent->position( ).toPoint( ) );

        QPoint pt = moveEvent->position( ).toPoint( );

        QPoint globalPos = widget->mapFromGlobal( QPoint( 0, 0 ) );

        QToolTip::showText( pt, error.what( ), ui->timingTree );

ui->timingTree is of type QTreeWidget and error.what() is just a text string. What I need to know is how to put the showText box in the QTreeWidget instead of global coordinates.

I change the code to read:

            QPoint position =
                timingTree->mapToGlobal( moveEvent->position( ).toPoint( ) );

            QToolTip::showText( position, error.what( ), ui->timingTree );

and this works.

You have to convert the local coordinates to the global ones: https://doc.qt.io/qt-6/qwidget.html#mapToGlobal
