Swing JTextField如何删除边框？ [英] Swing JTextField how to remove the border?

问题描述

无论如何要删除 JTextField 中的边框？

Is there anyway to remove a border in a JTextField?

txt = new JTextField();
txt.setBorder(null);   // <-- this has no effect.

我真的希望它看起来像 JLabel - 但我仍然需要它是 JTextField 因为我希望人们能够突出显示它。

I would really want it to look like a JLabel - but I still need it to be a JTextField because I want people to be able highlight it.

推荐答案

从你以前的答案问题你知道一些PL& Fs可能会破坏边界。

From an answer to your previous question you know that some PL&Fs may clobber the border.

显而易见的解决方案是覆盖 setBorder PL& F正在调用的方法，并放弃更改。

The obvious solution is to therefore override the setBorder method that the PL&F is calling, and discard the change.

JTextField text = new JTextField() {
    @Override public void setBorder(Border border) {
        // No!
    }
};
