问题描述:

Does Tkinter provide a way to temporarily turn off screen updates (when performing a large amount of screen activity) and then turn on screen updates when the UI updates are complete? Many GUI frameworks have this feature. wxPython provides Freeze and Thaw methods for this functionality. The Windows Win32api supports this as well via LockWindowUpdate( hWnd | 0 ). Googling on "tkinter freeze thaw" and "tkinter lockwindowupdate" came up emtpy.

网友答案:

No, Tkinter has no such thing. However, the screen is only updated via the event loop, so if all of your "large amount of screen activity" is happening in a single method, none of the activity will show up until your method finishes and the event loop is re-entered (or you explicitly call .update_idletasks())
