Description
When trying to use ScrollView with content that fills ScrollView, but has some minimum width/height, there are errors printed and scrollbars don't work as expected, when main window is resized. The errors are:
qrc:/qt-project.org/imports/QtQuick/Controls/Windows/ScrollView.qml:60:27: QML ScrollBar: Binding loop detected for property "visible"
1) Exapmle, which also prints "QML ScrollView: Binding loop detected for property "implicitHeight"" for some reason
Window {
width: 400
height: 400
visible: true
ScrollView {
id: scrollId
anchors.fill: parent
Rectangle {
id: contentId
color: "blue"
implicitWidth: scrollId.width < 300 ? 300 : scrollId.width
implicitHeight: scrollId.height < 300 ? 300 : scrollId.height
}
}
}
2) Example has the same result, but without "implicitHeight" error.
Window {
width: 400
height: 400
visible: true
ScrollView {
id: scrollId
anchors.fill: parent
contentWidth: contentId.implicitWidth
contentHeight: contentId.implicitHeight
Rectangle {
id: contentId
color: "blue"
implicitWidth: scrollId.width < 300 ? 300 : scrollId.width
implicitHeight: scrollId.height < 300 ? 300 : scrollId.height
}
}
}
3) Another example, same result.
Window {
width: 400
height: 400
visible: true
ScrollView {
id: scrollId
anchors.fill: parent
contentWidth: width < 300 ? 300 : width
contentHeight: height < 300 ? 300 : height
Rectangle {
id: contentId
color: "blue"
anchors.fill: parent
}
}
}
4) This example for some reason works as expected regarding the scrollbars, BUT still prints the "visible binding" errors (although much less often)
Window {
width: 400
height: 400
visible: true
ScrollView {
id: scrollId
anchors.fill: parent
Rectangle {
id: contentId
color: "blue"
implicitWidth: parent.parent.width < 300 ? 300 : parent.parent.width
implicitHeight: parent.parent.height < 300 ? 300 : parent.parent.height
}
}
}
If I remember correctly, then I had this problem in Qt 5 too.
