Bindable-only properties of type qreal/double don't work from QML

XMLWordPrintable

    • All

      When providing properties with only the BINDABLE keyword, QML silently ignores them.

      I try to pass the following properties to a QML Rectangle:

          Q_PROPERTY(qreal x BINDABLE getBindableX FINAL)
    Q_PROPERTY(qreal y BINDABLE getBindableY FINAL)
    Q_PROPERTY(qreal z BINDABLE getBindableZ FINAL)
    Q_PROPERTY(qreal width BINDABLE getBindableWidth FINAL)
    Q_PROPERTY(qreal height BINDABLE getBindableHeight FINAL)
    Q_PROPERTY(bool bVisible BINDABLE getBindableVisible FINAL)

      Members are

          QProperty<qreal> m_X;
    QProperty<qreal> m_Y;
    QProperty<qreal> m_Z;
    QProperty<qreal> m_Width;
    QProperty<qreal> m_Height;
    QProperty<bool> m_bVisible;

      Getters are like this:

      QBindable<qreal> PropertyClass::getBindableX() const
{
    return &m_X;
}

      Only the bool works, the qreal ones don't (I also tried double, but no change).

      Full sample attached. The sample should show a blinking red rectangle that slowly moves around.
