java有更好的替代g.drawString（）/g2D的方法。抽绳（）？（已解决）
一段时间以来，我一直试图将文本放到一个已经存在的窗口上。 我希望能够添加，删除，安排和重新排列整个屏幕上的段落
起初，我尝试添加文本组件，延迟了几秒钟。 接下来，我在JPanel derivate的绘画组件中试验了几何体，很高兴看到所有的东西都是瞬间出现的，并且产生了一种错觉，认为文本会表现出相同的行为。但是当我尝试drawString（）方法时，遇到了与以前类似的延迟。 也许这是我的电脑的问题，其他地方不会发生。 不过我还是想补救一下
最后我写了这个怪物：

…这很好，但有一个问题，我需要从我想要使用的任何字体转录所有几何信息-因此我不太确定我是否应该继续使用它，或者这只是浪费时间
更新：在一个不同的问题下，我发现drawString（）只需要几秒钟就可以加载绘制第一个单词时使用的字体。在那之后，它显然立即起作用（出于实际目的）——我不知道为什么我从来没有想过要检查我要求计算机绘制的第二行文本会发生什么
