QTreeView and d&d

[FuturePrimitive]

Hello

Im facing a little problem regarding QTreeView and drag&drop.

I want to restrict drop only in between the items. I found a good working suggestion on forum so this was not a big deal.

The problem is that i want to restrict items being dropped into different columns, lets say i have file, size and date column and i dont want the file item end up in the date or size column.

right now im using this inherited model class based on the suggestion i mentioned before.

class Model : public QStandardItemModel
{
public:
	Model(int rows, int cols, QObject* parent = 0) : QStandardItemModel(rows, cols, parent)
	{
	}
 
	Qt::ItemFlags flags(const QModelIndex& inIndex) const
	{
 
			if(!inIndex.isValid() )
				return  Qt::ItemIsDropEnabled; 
 
 
		return Qt::ItemIsDragEnabled | Qt::ItemIsSelectable | Qt::ItemIsEnabled ;
	}
};

class Model : public QStandardItemModel
{
public:
	Model(int rows, int cols, QObject* parent = 0) : QStandardItemModel(rows, cols, parent)
	{
	}
	
	Qt::ItemFlags flags(const QModelIndex& inIndex) const
	{
			
			if(!inIndex.isValid() )
				return  Qt::ItemIsDropEnabled; 
			
			
		return Qt::ItemIsDragEnabled | Qt::ItemIsSelectable | Qt::ItemIsEnabled ;
	}
};

To copy to clipboard, switch view to plain text mode 

Is there a way to do this without completely new customized QTreeView?

Or maybe is there better component for this particular purpose than QTreeView?



thanks a lot!

Ok i sorted it out and in case someone is facing the same problem.

i used the code in previous post for the model of treeview and made a sub-class of QTreeView with this dropEvent:

void CTreeView::dropEvent(QDropEvent *event)
{
	if(event->pos().x() > this->columnWidth(0))
		event->setPoint(QPoint(this->columnWidth(0)/2,event->pos().y()));
 
	QTreeView::dropEvent(event);
}

void CTreeView::dropEvent(QDropEvent *event)
{
	if(event->pos().x() > this->columnWidth(0))
		event->setPoint(QPoint(this->columnWidth(0)/2,event->pos().y()));
	
	QTreeView::dropEvent(event);
}

To copy to clipboard, switch view to plain text mode 

this is restriction to first column and any attempst to drop into other columns will be sent back to first column

I hope this helps to someone
