QTableView doubleclicked event not working

[jacek]

Any idea why no error occurred at compile?

Because SIGNAL is defined this way:

#define SIGNAL(a)        "2"#a

#define SIGNAL(a)        "2"#a

To copy to clipboard, switch view to plain text mode 

In other words, you pass strings to connect, not methods, so compiler can't check them. Although such errors can be detected at runtime, if you compile your application in debug mode and look at the console.

i think by default the doubleClicked signal makes the currend index to be selected in edit mode. But i am using QT 4.4 and i dont know have any idea on other versions

You can try this

QObject::connect(this, SIGNAL(doubleClicked(const QModelIndex &)), this, SLOT(edit(const QModelIndex &)));

I hope it will work. Once you double click in a cell it will be in edit mode but before emitting the double clicked signal (manually) you have to select the iindex by
this->setCurrentIndex(index);

Note: "this" is a object of QTableView. Lets see what happends

I wonder if anybody can help me. I'm having a similar problem with not being able to get "doubleClicked" to work on a QTableView. I'm using Qt 4.5.0 (commercial) on Windows XP.

I have a simple form with a QTableView. I create and set my model as follows:

g_paScheduleTableModel = new AScheduleTableModel(m_paSchedule);
ui.m_pqScheduleTableView->setModel( g_paScheduleTableModel );

g_paScheduleTableModel = new AScheduleTableModel(m_paSchedule);
ui.m_pqScheduleTableView->setModel( g_paScheduleTableModel );

To copy to clipboard, switch view to plain text mode 

I make sure the edit triggers are set and may my connections:

ui.m_pqScheduleTableView->setEditTriggers(QAbstractItemView::AllEditTriggers);
connect(ui.m_pqScheduleTableView, SIGNAL(clicked(const QModelIndex&)), this,
            SLOT(cellClicked(QModelIndex& )));
connect(ui.m_pqScheduleTableView, SIGNAL(doubleClicked( const QModelIndex&)),          this, SLOT(cellDoubleClicked(const QModelIndex&)));

ui.m_pqScheduleTableView->setEditTriggers(QAbstractItemView::AllEditTriggers);
connect(ui.m_pqScheduleTableView, SIGNAL(clicked(const QModelIndex&)), this,
            SLOT(cellClicked(QModelIndex& )));
connect(ui.m_pqScheduleTableView, SIGNAL(doubleClicked( const QModelIndex&)),          this, SLOT(cellDoubleClicked(const QModelIndex&)));

To copy to clipboard, switch view to plain text mode 

I receive the signals for "clicked" but I do not receive the signals "doubleClicked".

Any suggestions?
