Difference between ACTIVE and NORMAL state
问题 I have been using Tkinter from couple of weeks. One thing I have noticed is that the tkinter widgets (Button, etc.) have 3 states: NORMAL , ACTIVE and DISABLED . I understand the NORMAL and DISABLED states. Whats the difference between the ACTIVE and NORMAL states? 回答1: Tk sets state = ACTIVE when a mouse is over a non-DISABLED button option (i.e. NORMAL) It can then be made to appear raised, sunken, flat, flash etc. So basically, NORMAL enables a button while ACTIVE can change the appearance
