How to enable shortcut keys for custom widgets?

[Martin Drozdik]

I am trying to implement a customized QTableView integrated to the clipboard:

#include <QTableView>
#include <QAction>
 
class GeneralTableView : public QTableView
{
    Q_OBJECT
public:
    explicit GeneralTableView(QWidget *parent = 0);
 
public slots:
    void copy();
 
protected:
    QAction* copyAction_;
};
 
GeneralTableView::GeneralTableView(QWidget *parent) :
    QTableView(parent)
{
    copyAction_ = new QAction(this);
    copyAction_->setShortcut(QKeySequence::Copy);
    connect(copyAction_, SIGNAL(triggered()),
                 this, SLOT(copy()));
}

#include <QTableView>
#include <QAction>

class GeneralTableView : public QTableView
{
    Q_OBJECT
public:
    explicit GeneralTableView(QWidget *parent = 0);
    
public slots:
    void copy();
    
protected:
    QAction* copyAction_;
};

GeneralTableView::GeneralTableView(QWidget *parent) :
    QTableView(parent)
{
    copyAction_ = new QAction(this);
    copyAction_->setShortcut(QKeySequence::Copy);
    connect(copyAction_, SIGNAL(triggered()),
                 this, SLOT(copy()));
}

To copy to clipboard, switch view to plain text mode 

But copy() does not get executed when I hit ctrl+c. Only some default version of copy gets called. This copies only one cell in the clipboard and doesn't call my copy(). How can I fix this?

It will only get trigger when you have something to copy. Since you dont have anything then how it would get trigger? What it will copy?

I have an implementation for copy(), I just did not want to include it here for brevity. If I call copy() in another way, for example from a context menu, it does what it is supposed to do. It copies the entire selection to the clipboard. My problem is that it doesn't get called when I hit ctrl+c.
