注意这里的MyKGameCanvas 继承的KGameCanvas，而不是GameCanvas。KBOX的KGameCanvas类继承自GameCanvas，当并没有使用 GameCanvas那种使用线程监听状态的模型，而是重写了keypressed等方法来处理键盘事件。另外，KGameCanvas的重写的按钮事件 的处理已经实现了重复按键情况，而且可以指定重复按键的灵敏度，这点是非常好用的：）3GEYED4_%h~y#s,]&\

第一个参数是按钮的名字，第二参数是按钮类型，第三个参数是优先级，第四个参数是ID名，用于配置文件的映射，对应“ CMD.MYCMD.ACTION=action.TestAction”中的MYCMD，第五个参数是可传递参数，是一个Hashtable类型，用于 向Action传递参数（当然你喜欢的话，也可以将参数提到配置文件里去……）。3GEYE8ElR"T9VmC,DP
