How can I grey in/out a Swing Jbutton? What method can I use? Also, how can I make it greyed out by default in Netbeans?

回答by WilliamShatner
button.setEnabled(false);
The above should grey out a button just fine. I would make sure you have the documentation bookmarked or downloaded and read up on it a bit
上面的按钮应该变灰就好了。我会确保您将文档添加为书签或下载并仔细阅读

My assumption is that you are using the GUI creator in Netbeans. I would highly advise reading up on swing and learning the language rather than the IDE (there could be times when you have to use a different IDE than Netbeans and wouldn't have a clue how to do GUIs)
我的假设是您正在使用 Netbeans 中的 GUI 创建者。我强烈建议阅读 Swing 并学习语言而不是 IDE（有时您必须使用与 Netbeans 不同的 IDE，并且不知道如何制作 GUI）
