tooltipの内容を改行したい

[tdeng]

大分遅くなって申し訳ありませんが、次のような代わりのやり方でいかがでしょうか？

Code:

{let vb-for-tooltip:VBox =
    {VBox "This is a test line"}
}

{def cb =
    {CommandButton
        label = "&Click me!",
        tooltip= vb-for-tooltip,
        style = "standard",
        {on Action at btn:CommandButton do
            set btn.label = "Thanks for the &Click."
        }
    }
}

{value cb}
{let i:int = 1}

{CommandButton
    label="Add new long line to tooltip",
    {on Action do
        {vb-for-tooltip.add
            "new long long long long long long long long long long long long long long long long line:" & i
        }
        set i = i + 1
    }
}

{CommandButton
    label="Add new short line to tooltip",
    {on Action do
        {vb-for-tooltip.add
            "new short line:" & i
        }
        set i = i + 1
    }
}
