[Qt-interest] Displaying the File menu for Draged TreeWidget items

[Yuvaraj R]

Ok.

I  have overrdding the  QtreeWidget as follows

#include "treewidget_override.h"

TreeWidget_Override::TreeWidget_Override(QWidget *parent)

: QTreeWidget(parent)

{

}

 bool TreeWidget_Override::dropMimeData(QTreeWidgetItem *parent, int index,
const

QMimeData *data, Qt::DropAction action)

{

for( int i =0; i< this->topLevelItemCount();i++)

{

if (parent== this->topLevelItem(i)) //check accepting item is parent or not.

{

QByteArray text = data->data("foo/bar");

QDataStream ds(&text, QIODevice::ReadOnly);

while (!ds.atEnd()) {

QString str;

ds >> str;

for(int j=0; j<this->topLevelItem(i)->childCount();j++)

{

if(str ==this->topLevelItem(i)->child(j)->text(0))

{

return 0;

}

}

QTreeWidgetItem *newItem = new QTreeWidgetItem(parent);

newItem->setText(0, str);

}

}

}

}

 QStringList TreeWidget_Override::mimeTypes () const

{

QStringList qstrList;

qstrList.append("foo/bar");

return qstrList;

}

 Qt::DropActions TreeWidget_Override::supportedDropActions () const

{

return Qt::CopyAction | Qt::MoveAction;

}

QMimeData *TreeWidget_Override::mimeData(const QList<QTreeWidgetItem *>
items) const

{

QByteArray text;

QDataStream ds(&text, QIODevice::WriteOnly);

for (int i=0;i<items.size();i++)

ds << items.at(i)->text(0);

QMimeData *md = new QMimeData;

md->setData("foo/bar", text);

return md;

}
