DropMimeData is not getting called for extended QTableWidget

vikas2all

I have extended QTableWidget to create a custom tableWidget. I want to override the dropMimeData method. But dropMimeData() is not getting called.

Here is my code.

mytablewidget1.h
@
#include <QtGui>

class myTableWidget1 : public QTableWidget
{
Q_OBJECT
public:

myTableWidget1(QWidget *parent = 0);

virtual bool dropMimeData(int row, int column, const QMimeData *data, Qt::DropAction action);
QStringList mimeTypes() const;
Qt::DropActions supportedDropActions () const;

};@

mytablewidget.cpp

@
#include "mytablewidget1.h"
#include <iostream>

myTableWidget1::myTableWidget1(QWidget *parent) :
QTableWidget(3,3,parent)
{
this->dragEnabled();
setSelectionMode(QAbstractItemView::SingleSelection);
setDragDropMode(QAbstractItemView::InternalMove);

QTableWidgetItem *item=new QTableWidgetItem();
item->setText("1,1");
setItem(1,1,item);

item=new QTableWidgetItem();
item->setText("2,2");
setItem(2,2,item);

}

bool myTableWidget1::dropMimeData(int row, int column, const QMimeData *data, Qt::DropAction action)
{
std::cout<<"in dropMineData......."<<std::endl;

    return true;

}

QStringList myTableWidget1::mimeTypes () const
{

    QStringList qstrList;

    qstrList.append("text/uri-list");
    return qstrList;

}

Qt::DropActions myTableWidget1::supportedDropActions () const
{
return Qt::CopyAction | Qt::MoveAction;
}@

main.cpp

@
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
myTableWidget1 *dialog = new myTableWidget1(5,5);

dialog->show();
return app.exec(&#41;;

}@

You did not set the drag/drop on the viewport. From the "docs:":http://doc.qt.nokia.com/4.7/model-view-programming.html#using-drag-and-drop-with-item-views

@
QListWidget *listWidget = new QListWidget(this);
listWidget->setSelectionMode(QAbstractItemView::SingleSelection);
listWidget->setDragEnabled(true);
listWidget->viewport()->setAcceptDrops(true);
listWidget->setDropIndicatorShown(true);
@

The method you use (dragEnabled) does not enable it, it is a getter.

Setting DragDropMode to QAbstractItemView::DragDrop worked for me. Earlier i was using setDragDropMode(QAbstractItemView::InternalMove).
