QGraphicsTextItem focus problem

[jpn]

How about enabling/disabling the action on the fly, more or less like this:

class MyTextItem : public QGraphicsTextItem // QGraphicsTextItem inherits QObject
{
	Q_OBJECT
	...
 
signals:
	void editing(bool);
 
protected:
	void focusInEvent(QFocusEvent* event) {
		QGraphicsTextItem::focusInEvent(event);
		emit editing(true);
	}
 
	void focusOutEvent(QFocusEvent* event) {
		QGraphicsTextItem::focusOutEvent(event);
		emit editing(false);
	}
};
 
connect(textItem, SIGNAL(editing(bool)), deleteAction, SLOT(setDisabled(bool)));

class MyTextItem : public QGraphicsTextItem // QGraphicsTextItem inherits QObject
{
	Q_OBJECT
	...

signals:
	void editing(bool);

protected:
	void focusInEvent(QFocusEvent* event) {
		QGraphicsTextItem::focusInEvent(event);
		emit editing(true);
	}

	void focusOutEvent(QFocusEvent* event) {
		QGraphicsTextItem::focusOutEvent(event);
		emit editing(false);
	}
};

connect(textItem, SIGNAL(editing(bool)), deleteAction, SLOT(setDisabled(bool)));
