@jpnurmi thx again
only had to change the implicitHeight:
Tumbler {
id: tumbler
model: 10
visibleItemCount: 5
implicitHeight: visibleItemCount * 24
delegate: Text {
property int displacement: Math.abs(Tumbler.displacement)
id: label
text: modelData
color: displacement == 0 ? Material.primaryTextColor : Material.secondaryTextColor
font: tumbler.font
scale: displacement == 0 ? 1.20 : 1.0
horizontalAlignment: Text.AlignHCenter
verticalAlignment: Text.AlignVCenter
}
}
while flicking the tumbler there's a noticable delay before only the selected number will be scaled,
but I can live with this.
