Drag and Drop, QListWidget, and QApplication:mouseButtons()

[ChanchoCiego]

Hello

I have an application with a QListWidget, in the window of the application (MainWindow) a slot there is
@
void evLstWdgPressed(QModelIndex index);
@

I connect with:

@
connect(
ui->listWidget,
SIGNAL(pressed(QModelIndex)),
this,
SLOT(evLstWdgPressed(QModelIndex))
);
@

and implemented as well:

@
void MainWindow::evLstWdgPressed(QModelIndex index)
{
if ( QApplication::mouseButtons() == Qt::NoButton )
ui->text->appendPlainText("\tQt::NoButton");
else if ( QApplication::mouseButtons() == Qt::LeftButton )
ui->text->appendPlainText("\tQt::LeftButton");
else if ( QApplication::mouseButtons() == Qt::MidButton )
ui->text->appendPlainText("\tQt::MidButton");
else if ( QApplication::mouseButtons() == Qt::MiddleButton )
ui->text->appendPlainText("\tQt::MiddleButton");
else if ( QApplication::mouseButtons() == Qt::XButton1 )
ui->text->appendPlainText("\tQt::XButton1");
else if ( QApplication::mouseButtons() == Qt::XButton2 )
ui->text->appendPlainText("\tQt::XButton2");
else if ( QApplication::mouseButtons() == Qt::RightButton )
ui->text->appendPlainText("\tQt::RightButton");
else
ui->text->appendPlainText("\tNO DETECTED " + tr("%1").number(QApplication::mouseButtons()));

QDrag *drag = new QDrag(this);
QMimeData *mimeData = new QMimeData;

QList <QUrl> urls;
QUrl url("file:///E:/arch.zip");

urls.append(url);
mimeData->setUrls(urls);
drag->setMimeData(mimeData);

drag->exec&#40;Qt::CopyAction&#41;;

}
@

The problem is that QApplication:mouseButtons () detects the button pressed the first time that runs the signal, the rest of the times do not detect it.

I try to detect button to differentiate a drag and drop of a right click to display a shortcut menu.

Any suggestions? What I am doing wrong?

Thanks a lot.
