When OverrunStyle.CLIP is selected for a Button, the label is not clipped. Instead characters are removed in the middle of the label (see attached screenshot).

[code]
Stage {
    scene: Scene {
        content: [
            Button {
                text: "Button Label"
                layoutInfo: LayoutInfo {
                    height: 20
                    width: 50
                }
                textOverrun: OverrunStyle.CLIP
            }
        ]
    }
}
[/code]
