QML Slider value is not updating visually - qt

Question

I am trying to create a Slider in QML. The slider's maximumValue property can change depending on certain states in my application. When the maximumValue property changes I would like to "reset" my slider so that its value property is at the maximumValue. The problem what I am encountering is that when I change the maximumValue property, my value property changes to the right property, but visually it stays at the previous maximumValue property until I don't click on the handle for example.
Here is a simple dummy code, which reproduces this issue:
import QtQuick 2.5
import QtQuick.Window 2.2
import QtQuick.Controls 1.4
import QtQuick.Controls.Styles 1.2
ApplicationWindow {
visible: true
width: 640
height: 480
title: qsTr("Hello World")
property int maxVal: 1
Item {
width: 20
height: 200
Slider {
anchors.fill: parent
orientation: Qt.Vertical
maximumValue: maxVal
minimumValue: 0
value: 1
stepSize: 1.0
style: SliderStyle {
groove: Rectangle {
width: control.height
height: control.width
color: "red"
}
handle: Rectangle {
width: 20
height: 20
color: "green"
Text {
anchors.centerIn: parent
text: control.value
}
}
}
onMaximumValueChanged: value = maximumValue
}
}
Button {
anchors.right: parent.right
text: "Press Me"
onClicked: maxVal = 100
}
}
Below you can see some screenshots of certain stages.
When the application opens:
When I press the "Press Me" button, which sets the maximumValue to 100 from 1. As you can see the value did change from 1 to 100, but visually it stayed at the 1 position:
Finally when I click on the handler of the slider (green rectangle), then it updates and switches value to 1 from 100.
Here is the same thing as a gif:
Anybody encountered this issue before?

Answer 1

It looks like QTBUG-63354, which will be fixed in Qt 5.9.3.
