我们该如何动词？

Question

例如，我想在我的主框架中使用一个类似于“系统”的句子，它可以从框架的左侧移动到框架的右侧或向上移动到向下。我该怎么做？

Answer 1

I think you are trying to implement a sliding text. You may use the Timer class to set your label's(or whatever the component is) position. Every time the Timer ticks, you may increment the position or decrement it, the rest is up to your choice.

And I also must say, that you should be more clear when asking questions.

Answer 2
