Description
From the documentation, it says that
implicitContentWidthPolicy provides an easy way to control how the implicitContentWidth is calculated, which in turn affects the implicitWidth of the ComboBox and ensures that text will not be elided.
However, the implicitContentWidth will only affect the implicitWidth for the Basic, Fusion, Material and Universal styles (and perhaps also the native styles, which I haven't checked yet).
But it won't work for the Imagine style.
Here is the implicitWidth binding for the Fusion style:
implicitWidth: Math.max(implicitBackgroundWidth + leftInset + rightInset,
implicitContentWidth + leftPadding + rightPadding)
And here is the implicitWidth binding for the Imagine style:
implicitWidth: Math.max(implicitBackgroundWidth + leftInset + rightInset,
contentItem.implicitWidth + background ? (background.leftPadding + background.rightPadding) : 0)
As you can see, the implicitContentWidth isn't a part of the implicitWidth binding for the Imagine style.
The Imagine style implicitWidth appears to have been overlooked in the original patch: https://codereview.qt-project.org/c/qt/qtquickcontrols2/+/225925
Reproduce with the following qml code:
ComboBox {
implicitContentWidthPolicy: ComboBox.WidestTextWhenCompleted
model: ListModel {
ListElement {
name: qsTr("12345678901234567890")
}
ListElement {
name: qsTr("123")
}
}
}
