Trouble with QTableWidget right-click event

Imhotep

I was able to simulate the Right-Click event by subclassing the QTableWidget:

header file:
@
#ifndef QRIGHCLICKTABLE_H
#define QRIGHCLICKTABLE_H

#include <QTableWidget>
#include <QMouseEvent>

class QRightClickTable : public QTableWidget
{
Q_OBJECT

public:
explicit QRightClickTable(QWidget *parent = 0);

private slots:
void mousePressEvent(QMouseEvent *e);

signals:
void rightClicked();

public slots:

};

#endif // QRIGHCLICKTABLE_H
@

cpp file
@
QRightClickTable::QRightClickTable(QWidget *parent) :
QTableWidget(parent)
{
}

void QRightClickTable::mousePressEvent(QMouseEvent *e)
{
if(e->button()==Qt::RightButton)
emit rightClicked();
}

QRightClickTable *tablewidget = new QRightClickTable(this);
ui->gridLayout->addWidget(tablewidget);
connect(tablewidget, SIGNAL(rightClicked()), this, SLOT(onRightClicked()));

void MainWindow::onRightClicked()
{
qDebug() << "User right clicked me";
}
@

Now, right-click works correctly, but there are other problems with QTableWidget: all other mouse events, such as the left click to select a cell, no longer work. Can you help me? I know I need to call the base class implementation in your override of mousePressEvent, you could show me how?

Hi,

You need to call the base class implementation of the method if you want the original behavior plus your own.

Could you show me how?

Please, do your homework, this is basic C++

@
void QRightClickTable::mousePressEvent(QMouseEvent *e)
{
if(e->button()==Qt::RightButton) {
emit rightClicked();
}
QTableWidget::mousePressEvent(QMouseEvent *e);
}
