problem with focusEvent

[wagmare]

hi friends,

my task is to show a list widget when user press or click on a lineEdit() ...
i made a small class popWidget derived from QListWidget and using the event filter on lineEdit i am showing the popWidget using show()...

eventFilter( QObject *obj, QEvent *ev )
{
        if (obj == _hwListView)
        {
                if (ev->type() == QEvent::FocusIn)
                {
                        _hwListPop->show();
                        _hwListPop->setFocus(Qt::PopupFocusReason);
                        return true;
                }else
                        return false;
        }

eventFilter( QObject *obj, QEvent *ev )
{
        if (obj == _hwListView)
        {
                if (ev->type() == QEvent::FocusIn)
                {
                        _hwListPop->show();
                        _hwListPop->setFocus(Qt::PopupFocusReason);
                        return true;
                }else
                        return false;
        }

To copy to clipboard, switch view to plain text mode 

then comes the problem with hide() when the user press somewhere in the mainwindow ..


i reimplemented focusOutEvent() on popWidget to hide() it when it lost its focus ..

PopWidget::focusOutEvent(QFocusEvent *event)
{
        this->hide();
}

PopWidget::focusOutEvent(QFocusEvent *event)
{
        this->hide();
}

To copy to clipboard, switch view to plain text mode 

actually that lineEdit is a part of the object say subWindow of mainWindow so when i press any where in subWindow i can manage to hide the popWidget but not in the mainWindow ..

how can i send the particular event to the mainWindow ..?

please help me ...
