问个奇葩问题，怎么让带选项菜单中的选项字符串换行

salvareless

如题，自己改写了一个自用脚本，基本功能是在主菜单中加入一个能力选项，进去之后是一个Command菜单，目前已经实现改变单个Command选项的宽和高，但是不知道怎么控制Command选项里面的文字，它依旧是靠上方显示的，想法有两个：
1·让显示的字符串可以完全居中显示而不是水平方向居中了，但竖直方向依旧是靠上显示的。然后就是让显示的字符串具备换行的功能。
2·当然想要实现我想要的效果其实还可以用另一个方式，那就是为Command选项增加一个背景图片。大窗口的背景我倒是弄出来了，但是Command选项的背景是怎么也搞不定。
哪位大神路过给指点一下迷津呗~~~~~以上两个思路只要有能一个实现就OK

目前做到这个程度= =

直接把文字做成图片格式，调整好文字布局，然后添加到页面中，是否可行

salvareless

欸~~~~尝试了很多种方法，都不行，根本就不能调用出来图片，不知道是窗口属性的问题还是怎样。
无奈的我只能把调用公共事件的代码插到生成主窗口的位置，然后把下面全部屏蔽了，再然后………………就用公共事件做了一个这样的功能= =
