QVariant was using QColor::name() to convert a color to string, which by default loses alpha value. The patch is fixing the problem by always including the alpha value in the string when required. [ChangeLog][Core][Variant] QVariant(QColor)::toString() uses QColor::HexArgb format when the alpha component is different from 1. Task-number: QTBUG-37851 Change-Id: I887460c1ea151180ba99d64dd873ba9d6e2268f2 Reviewed-by: Simon Hausmann <simon.hausmann@theqtcompany.com>
