Bounding box of wrapped text

问题

I want to draw a rectangle around a QML Text object that is using word wrapping. TextMetrics seems like it would be ideal, but it does not appear to support wrapped text.

How can I measure how text is laid out in a Text object? Must I match the wrapping logic and manually calculate the offsets using TextMetrics and FontMetrics?

回答1:

You can use contentWidth and contentHeight:

Text {
    text: "..."
    wrapMode: Text.Wrap

    Rectangle {
        border.color: "red"
        color: "transparent"
        width: parent.contentWidth
        height: parent.contentHeight
    }
}
