How to catch MouseBottonPress for QListWidget

[Levon Nikoghosyan]

QEventFilter doesn't handle QEvent:MouseButtonPress for QListWidget but reacts to QEvent::KeyPress .

Below is a sample code :

//////////////////////////////HPP File /////////////////////////////////////
class key_press_filter: public QObject
{
        Q_OBJECT
protected:
        bool eventFilter(QObject *obj, QEvent *event);
};
 
class my_list: public QListWidget
{
	Q_OBJECT
public:
	my_list(QWidget* p = 0);
	virtual ~my_list();
};
////////////////////////////////////////////////////////////////////////////////
//////////////////////////////CPP File /////////////////////////////////////
 
my_list::my_list(QWidget* p): QListWidget(p)
{
	setSelectionMode(QAbstractItemView::MultiSelection);
	addItem("First");
	addItem("Second");
	addItem("Third");
	key_press_filter* kf = new key_press_filter();
        installEventFilter(kf);
 
}
bool key_press_filter::eventFilter(QObject *o, QEvent *e)
{
	my_list* f = static_cast<my_list*>(o);
        if (e->type() == QEvent::MouseButtonPress||
			e->type() == QEvent::KeyPress) {
                QMouseEvent *m = static_cast<QMouseEvent*>(e);
                f->addItem("aaaaaaaaaaaa");
        } else {
                // standard event processing
                return QObject::eventFilter(o, e);
        }
}

//////////////////////////////HPP File /////////////////////////////////////
class key_press_filter: public QObject
{
        Q_OBJECT
protected:
        bool eventFilter(QObject *obj, QEvent *event);
};

class my_list: public QListWidget
{
	Q_OBJECT
public:
	my_list(QWidget* p = 0);
	virtual ~my_list();
};
////////////////////////////////////////////////////////////////////////////////
//////////////////////////////CPP File /////////////////////////////////////

my_list::my_list(QWidget* p): QListWidget(p)
{
	setSelectionMode(QAbstractItemView::MultiSelection);
	addItem("First");
	addItem("Second");
	addItem("Third");
	key_press_filter* kf = new key_press_filter();
        installEventFilter(kf);
	
}
bool key_press_filter::eventFilter(QObject *o, QEvent *e)
{
	my_list* f = static_cast<my_list*>(o);
        if (e->type() == QEvent::MouseButtonPress||
			e->type() == QEvent::KeyPress) {
                QMouseEvent *m = static_cast<QMouseEvent*>(e);
                f->addItem("aaaaaaaaaaaa");
        } else {
                // standard event processing
                return QObject::eventFilter(o, e);
        }
}
