Answer 1

呵呵，我在jbuilder中，要改的话先把layout转成xy，调好后再换回原来的layout...

Answer 2

diggywang(Miner Lover！说的什么意思,我不太明白,能帮我改下吗?

Answer 3

ailu5949() 说的打空格是什么意思,我根本打不了空格啊

Answer 4

datefromJLabel = new JLabel("日期从");
改为datefromJLabel = new JLabel("日期从   ");
给它的初值多几个"   "就好啦你的布局有点乱

Answer 5

我的布局就是很乱啊,不会弄啊因为我是把一个类的按钮什么的放在另外一个类里显示的,所以null布局不能用啊空格的办法对label还不错,就是别的那些控件都拉不开
