6.6.3, 6.7.0
Description
Scrolling sensitivity is drastically reduced with Qt6.6 and above. Same code scrolling speed works as it should with earlier version of Qt. i.e. 6.5.3
Even using ListView.highlightMoveDuration or highlightMoveVelocity has no effect.
Attached example reproduces it. Run the example and using mouse wheel scroll up/down
import QtQuick 2.15 import QtQuick.Controls 2.15 ApplicationWindow { visible: true width: 640 height: 480 title: "Scrollbar Scroll Speed Example" ScrollView { width: parent.width height: parent.height ListView { width: parent.width model: 100 // Just for demonstration highlightMoveDuration:8000 highlightMoveVelocity :200 delegate: Item { width: parent.width height: 50 Text { anchors.centerIn: parent text: "Item " + index } } } ScrollBar.vertical: ScrollBar { id: scrollbar width: 12 height: parent.height policy: ScrollBar.AlwaysOn stepSize: 100 // Adjust this value to increase scroll speed background: Rectangle { color: "#dddddd" } Rectangle { color: "#aaaaaa" width: parent.width height: Math.max((parent.height / parent.contentHeight) * parent.height, 20) } } } }
