A "clicked" signal may sometimes be required from a label, but there is no "clicked" signal emitted by QLabel. You can work around this easily by making a QPushButton like a label by setting the 'flat' property.

However, if there are other properties of a QLabel object that you need, here is a code snippet for a custom QLabel which can emit a signal: 'clicked'. In other words, a Clickable QLabel!

Header

class ClickableLabel : public QLabel
{
Q_OBJECT
public:
    explicit ClickableLabel( const QString& text="", QWidget* parent=0 );
    ~ClickableLabel();
signals:
    void clicked();
protected:
    void mousePressEvent(QMouseEvent* event);
};

Source

ClickableLabel::ClickableLabel(const QString& text, QWidget* parent)
    : QLabel(parent)
{
    setText(text);
}

ClickableLabel::~ClickableLabel()
{
}

void ClickableLabel::mousePressEvent(QMouseEvent* event)
{
    emit clicked();
}

What we do here is simple: Catch the mouse press event on the label. Then emit 'clicked' signal. We could as well make the signal be emitted when mouse gets released. This is let to be a decision of the developer.
