设置键盘监听

  1. //需要点击一下按钮后，按钮获得焦点，才会触发以下方法  
  2. btn.setOnKeyPressed(new EventHandler<KeyEvent>() {
  3.             @Override
  4.             public void handle(KeyEvent event) {
  5.                 switch (event.getCode()){
  6.                     case A:
  7.                         System.out.println("A");
  8.                         break;
  9.                     case B:
  10.                         break;
  11.                     case F10:
  12.                         break;
  13.                     default:
  14.                         //其他键盘
  15.                         break;
  16.                 }
  17.             }
  18.         });
  20. //松开键盘监听
  21. btn.setOnKeyReleased(new EventHandler<KeyEvent>() {
  22.     @Override
  23.     public void handle(KeyEvent event) {
  25.     }
  26. });

设置键盘快捷键

  1. Button b2 = new Button("Hello")
  3. // 第一种
  4. KeyCombination kc1 = new KeyCodeCombination(KeyCode.C, KeyCombination.ALT_DOWN, KeyCombination.CONTROL_DOWN);
  5. Mnemonic mnemonic1 = new Mnemonic(b2, kc1);
  6. scene.addMnemonic(mnemonic1);
  8. // 第二种
  9. KeyCombination kc2 = new KeyCharacterCombination("O", KeyCombination.ALT_DOWN);
  10. Mnemonic mnemonic2 = new Mnemonic(b2, kc2);
  11. scene.addMnemonic(mnemonic2);
  13. //一般建议用这种，前几种在兼容上似乎或多或少有些问题
  14. KeyCombination kccb = new KeyCodeCombination(KeyCode.K,
  15.                                              KeyCombination.SHIFT_DOWN);
  17. scene.getAccelerators().put(kccb, new Runnable() {
  18.     @Override
  19.     public void run() {
  20.         System.out.println("run");
  21.     }
  22. });
