我的程序的目标是从整数值的字符串树Map中打印一个单词标记云。数字最大的字符串将是字体最大的单词，以此类推。唯一的问题，我似乎是与交叉的话，当印刷。我一直在使用矩形与文本内，以检测交叉点使用交集方法。我的想法是从中间开始所有的单词，然后在一个随机的方向（上，下，左，右）移动每个单词，直到文本框不再与任何其他框相交。这是为了确保单词之间的空白尽可能少，没有交叉。这是我的密码：

我没有收到任何错误信息，但我的图形面板拒绝显示除白色背景以外的任何内容。而且每次我试图关闭图形窗口时，它都不会关闭。有没有其他方法来移动字符串？另外，如何在标记云中实现水平和垂直字符串，而不仅仅是我所拥有的水平字符串？
