java swing 中怎么使控件换行

Answer 1

使用GridBagLayout，大致这样：
GridBagLayout
gridbag
=
new
GridBagLayout();
GridBagConstraints
c
=
new
GridBagConstraints();
setLayout(gridbag);
c.fill
=
GridBagConstraints.BOTH;
c.weightx
=
1.0;
gridbag.setConstraints(c);
add(new
Button("button1"));
c.gridwidth
=
GridBagConstraints.REMAINDER;
//这是本行的最后一个
gridbag.setConstraints(c);
add(new
Button("button2"));
c.weightx
=
0.0;
//重新开始一行
gridbag.setConstraints(c);
add(new
Button("button3"));

Answer 2

一些控件比如jlabel应该是支持html格式的。你在jlabel的setText方法里面放一段html代码，换行用
就可以。
