如何制作与文本大小完全相同的按钮？

Question

Is it possible to make a JButton take exactly the size of its text? Since by default, a JButton will have a small amount of padding (both horizontal and vertical) around its text. I would like to remove that padding.

Answer 1

JButton has a border by default, you can remove it:

button.setBorder(null);

---

If you want to keep the border, reduce the margin (see Eugenes answer )

Answer 2

Clear out the margins in the button with setMargin .

Removing the border has the side-effect of removing the border. If you only want to clear out the margins, use the setMargin method to set the margins all to zero.

button.setMargin(new Insets(0,0,0,0));
