推荐答案
方法 setMnemonic(char mnemonic)
已过时,您应该使用 setMnemonic(int mnemonic)
并使用相应的 VK_E
。
The method setMnemonic(char mnemonic)
is obsolete, you should use setMnemonic(int mnemonic)
with the appropriate VK_E
instead.
在任何情况下,默认行为都是为第一次出现的字母加下划线(如果存在)。如果你想自定义这个东西,你应该看看 AbstractButton
类,它有一个方法(doc 这里:
In any case the default behaviour is to underline first occurrence of the letter, if present. If you want to customize this thing you should look at AbstractButton
class, it has a method (doc here:
public void setDisplayedMnemonicIndex(int index)
完全符合您的需要。所以:
that does exactly what you need. So:
openProjectMenuItem.setMnemonic(VK_E);
openProjectMenuItem.setDisplayedMnemonicIndex(9);
