Context Menu not working

[waynew]

Right click on the view, nothing happens, here's the code:

view = new QTableView();
connect(view, SIGNAL(customContextMenuRequested ( const QPoint &)), this, SLOT(viewMenu(const QPoint &)));
 
void MainWindow::viewMenu(const QPoint & pos)
{
QMenu *viewMenu = new QMenu("Edit Log", this);
viewMenu->setContextMenuPolicy(Qt::CustomContextMenu);
viewMenu->addAction("Edit");
viewMenu->popup(pos);
}

view = new QTableView();
connect(view, SIGNAL(customContextMenuRequested ( const QPoint &)), this, SLOT(viewMenu(const QPoint &)));

void MainWindow::viewMenu(const QPoint & pos)
{
QMenu *viewMenu = new QMenu("Edit Log", this);
viewMenu->setContextMenuPolicy(Qt::CustomContextMenu);
viewMenu->addAction("Edit");
viewMenu->popup(pos);
}

To copy to clipboard, switch view to plain text mode 

viewMenu is declared as a slot.

so, what have I done wrong?

[rainspider]

setContextMenuPolicy(Qt::CustomContextMenu);

This function must be called before emitting signal (customContextMenuRequested).
eg:

view = new QTableView();
view->setContextMenuPolicy(Qt::CustomContextMenu);
connect(view, SIGNAL(customContextMenuRequested ( const QPoint &)), this, SLOT(viewMenu(const QPoint &)));

and the pos must be translated form widget coordinates to screen coordinates.more information in Qt document,Please look for

customContextMenuRequested
