在以下代码片段中,我们有encryptButton()函数,它将设置控制第一个Entry框内容的encryptvalue StringVar。这个字符串被设置为我们通过调用ENC.encryptText()得到的结果,我们要加密的消息(encryptvalue的当前值)和keyvalue变量。decrypt()函数完全相同,只是我们将keyvalue变量设置为负数以解密消息: defencryptButton():encrypt...

Once the button status changes (I.e. Change from never-pressed status into pressed status), the program will wait one predetermined delay time instead of responding this change immediately. After this delay is over, the program will detect button status again. If the button status maintains, th...
