For completeness.
Gunnar Sletta just responded. The right QML code:
import QtQuick 2.0
import QtGraphicalEffects 1.0
Rectangle {
width: 800
height: 600
Rectangle{
id: brContainer
width: 500 + 16
height: 50 + 16
anchors.centerIn: parent
border.color: "red"
border.width: 1
Rectangle {
id: blackRect
width: 500
height: 50
color: "black"
anchors.centerIn: parent
visible: false
}
DropShadow {
anchors.fill: blackRect
horizontalOffset: 3
verticalOffset: 3
radius: 16
samples: 24
color: "#80000000"
transparentBorder: true;
source: blackRect
}
}
}
and https://bugreports.qt-project.org/browse/QTBUG-36689 is thereby
closed already.. Oh well, i'm glad i know how it should be done now.
