mac 中判断command键是否被按下

使用KeyEvent.isMetaDown()

实例:

/***
	 * 增加全局快捷键Shift+Tab<br>
	 * Ctrl+Shift+X
	 */
	private void addGlobalKey(){
		Toolkit toolkit = Toolkit.getDefaultToolkit();
		// 注册应用程序全局键盘事件, 所有的键盘事件都会被此事件监听器处理.
		toolkit.addAWTEventListener(
				new java.awt.event.AWTEventListener() {
					public void eventDispatched(AWTEvent event) {
						if (event.getClass() == KeyEvent.class) {
							KeyEvent kE = ((KeyEvent) event);
							// 处理按键事件 Shift+Tab
							if ((kE.getKeyCode() == KeyEvent.VK_TAB)//TODO 注意:Ctrl+Tab 是系统的快捷键,容易和程序混淆
									&& (((InputEvent) event)
											.isShiftDown())&& kE.getID() == KeyEvent.KEY_PRESSED) {
								int lastIndex=getLastIndex();
								if(lastIndex<0){
									return;
								}
//								indexList.add(tabbedPane.getSelectedIndex());
								tabbedPane_2.setSelectedIndex(lastIndex);
							} else if ((kE.getKeyCode() == KeyEvent.VK_X) && (((InputEvent) event)//发送请求
									.isShiftDown()) && (((InputEvent) event)
                                    .isAltDown()) && kE.getID() == KeyEvent.KEY_PRESSED) {//Alt+Shift+X
                                AutoTestPanel.this.currentRequestPanel.requestAction(null, true);
							} else if ((kE.getKeyCode() == KeyEvent.VK_M) && (!((InputEvent) event)//发送请求
									.isShiftDown()) && (((InputEvent) event)
                                    .isControlDown()) && kE.getID() == KeyEvent.KEY_PRESSED) {//Ctrl+Shift+M
                                DialogUtil.showMaximizeDialog(getCurrentRequestPanel().getRespTextArea_9());
							} else if ((kE.getKeyCode() == KeyEvent.VK_H) && (!((InputEvent) event)//发送请求
									.isShiftDown()) && (((InputEvent) event)
									.isControlDown()) && kE.getID() == KeyEvent.KEY_PRESSED) {//Ctrl+Shift+M
								TableUtil.showHelpDialog();
                            } else if (kE.getKeyCode() == KeyEvent.VK_K/*Ctrl +K*/
                                    && (kE.isControlDown()||kE.isMetaDown())
                                    && kE.getID() == KeyEvent.KEY_PRESSED) {
                                searchTextField.requestFocus();
                                searchTextField.selectAll();
                            }
                        }
					}
				}, java.awt.AWTEvent.KEY_EVENT_MASK);
