QTreeWidget internal move

[macman]

'pTreeWidget' was not declared in this scope

Na was mag das wohl sein? Der Pointer auf das TreeWidget.

Also ich habe es so gelöst:

Code: Alles auswählen

void MyTreeWidget::dragMoveEvent(QDragMoveEvent *event)
{
	bool isRootItem(false), isChildItem(false);
	
	QList<QTreeWidgetItem *> sel_items = selectedItems();
	for (int i=0; i<sel_items.size(); i++)
	{
		if (sel_items[i]->childCount()>0)
			isRootItem=true; //rootItem with children
		else if (indexOfTopLevelItem(sel_items[i]->parent())==-1)
			isRootItem=true; // rooItem without children
		else
			isChildItem=true;
	}
	
	if (isRootItem & isChildItem)  // if rootItems and childItems are selected
		event->ignore();
	else
	{
		QTreeWidgetItem *item = itemAt(event->pos());
		if(item)
		{
			if (!isRootItem && indexOfTopLevelItem(item->parent())==-1)
				event->accept();				
			else 
				event->ignore();
		}
		else if (isChildItem) // childItem can not become a rootItem
			event->ignore();
		else
			event->accept();
	}
}
