java-如何为JTextField映射选项操作(Mac键盘)？
作者：互联网
看起来只有up可以使用AWT来捕获选项(即添加键侦听器).有没有一种方法可以不必麻烦AWT？
解决方法:
用于JTextField的Mac OS X UI委托不会将alt↑绑定到任何Action.您可以自由地将组合绑定到您选择的任何操作.如How to Use Key Bindings所示,下面的示例将alt↑绑定到为JTextField定义的现有“插入符号开始行”,它将插入符号移动到行的开头.
final JTextField jtf = new JTextField("Test");
jtf.getInputMap().put(
KeyStroke.getKeyStroke(KeyEvent.VK_UP, KeyEvent.ALT_MASK),
"caret-begin-line");
可以找到更多示例here.如引用为here的键绑定实用程序中所示,JTextField按名称将以下WHEN_FOCUSED操作绑定到所指示的键.
