func (w *BaseWidget) StyleName() string {
    // ttk::button .b; winfo class .b  // ==> TButton
	r, _ := evalAsString(fmt.Sprintf("winfo class %v", w.id))
	return r
}

func (w *BaseWidget) StyleLookUp(name, option string) string {
    // ttk::style lookup style -option
    // ttk::style lookup 1.TButton -font  // [---> helvetica 24]
    r1, _ := evalAsString(fmt.Sprintf("ttk::style lookup %v -%v", name,option))
    return r1
}


func StyleConfigure(name string, options map[string]string) error {
    // ttk::style configure style ?-option ?value option value...? ?
    // ttk::style configure Emergency.TButton -foreground red -padding 10
    // ttk::button .b -text "Hello" -style "Fun.TButton"
    var tmp = ""
    for k,v := range options {
        tmp = tmp + "-" + k + " " + v + " "

}

func StyleMap(name string, options map[string]map[string]string) error{
    // ttk::style map style ?-option { statespec value... }?
    // ttk::style map TRadiobutton -foreground [list !pressed blue pressed yellow] -background [list selected black !selected white]
    var tmp1 = ""
    var tmp2 = ""
    for k1,v1 := range options {
        tmp2 = "[list "
        tmp1 = tmp1 + "-" + k1 + " "
        for k2,v2 := range v1 {
            tmp2 = tmp2 + k2 + " " + v2 + " "
        }
        tmp2 = tmp2 + "] "
        tmp1 = tmp1 + tmp2
    }
    // fmt.Println(fmt.Sprintf("ttk::style map %v %v", name,tmp1))
    return eval(fmt.Sprintf("ttk::style map %v %v", name,tmp1))
}

例子

fmt.Println(tk.TtkTheme.ThemeIdList(),tk.TtkTheme.ThemeId()) // 返回当前平台可用ttk主题，及默认使用的ttk主题
==> [xpnative clam alt classic default winnative vista] vista
tk.TtkTheme.SetThemeId("alt") // 设置ttk主题

// 为Radiobutton控件设置一个名为”1.TRadiobutton“ 风格
tk.StyleConfigure("1.TRadiobutton",map[string]string{"font":"{consolas 10}","foreground":"red","background":"white"})

// 为Radiobutton控件设置一个名为”1.TRadiobutton“ map风格
tk.StyleMap("1.TRadiobutton",map[string]map[string]string{"foreground":{"pressed":"yellow","!pressed":"blue"},
    "background ":{"selected":"black","!selected":"white"}})

rtn1 := tk.NewRadioButton(mw,"rtn1",)
rtn2 := tk.NewRadioButton(mw,"rtn2",)
rtn3 := tk.NewRadioButton(mw,"rtn3",)

rtn1.SetNativeAttribute("style","1.TRadiobutton")
rtn2.SetNativeAttribute("style","1.TRadiobutton")
rtn3.SetNativeAttribute("style","1.TRadiobutton")
