CalendarControlのスピンについて

[heavybugtracker]

こんな感じでしょうか？（違和感があるかと思いますが、これ以上のカスタマイズは、UIクラスを継承してやる必要があるようなきがします。。。）

{def samples =
{HBox
spacing = 9pt, margin = 9pt,
{CalendarControl}
}
}

{value
{install-style-sheet-on-Graphic
samples,
{StyleSheet
{StyleRule "SpinControl/decrease-button",
skin =
{ShadedSkinSpec
"chocolate", "darkorange",
overlay-decoration = "decrease-triangle",
highlight-boundary = .05,
corner-radius = 3
}
},
{StyleRule "SpinControl/increase-button",
skin =
{ShadedSkinSpec
"chocolate", "darkorange",
overlay-decoration = "increase-triangle",
highlight-boundary = .05,
corner-radius = 3
}
}
}
}
}
