[Interest] drag and drop disappear the item for windows, in Linux it fine

[Sujan Dasmahapatra]

Dear Friends

In my application I have implemented drag and drop on the treewidget
items. In linux its working fine but in windows I see when dragging and
dropping an item in the treewidget list, then from where the item is
dragged there's items name is disappearing but its child items are
present. And the item become inactive. Its working fine in Linux but in
windows I am facing this problem. Please give me some suggestions. Check
my drag and drop event.

 

[code]

void TreeWidget::dragMoveEvent(QDragMoveEvent * event)

{

        event->acceptProposedAction();

}

void TreeWidget::dragEnterEvent(QDragEnterEvent * event )

{

        Preprocessor = true;

        draggingItem = currentItem();

        event->acceptProposedAction();

        oldindex = indexOfTopLevelItem(currentItem());

}

void TreeWidget::dropEvent(QDropEvent * event )

{

        dropingOn = this->itemAt(event->pos());

        if(!dropingOn)

        return;

        if(dropingOn->parent())

        return;

        int dropingIndex = this->indexOfTopLevelItem(dropingOn);

        this->takeTopLevelItem(this->indexOfTopLevelItem(draggingItem));

        index = this->indexOfTopLevelItem(dropingOn);

        if(index < dropingIndex) index++;

        this->insertTopLevelItem(index, draggingItem);

}

[/code]
