wxPython - 按鈕動畫會減慢計算機的速度

Question

我正在製作一個wx應用程序，其中的按鈕應該在點擊時進入循環動畫。背景顏色是按鈕上的動畫。它在幾分鐘內運行良好，但是在幾分鐘後該應用程序開始變得沒有反應，甚至有時會使計算機崩潰。
動畫能夠運行很長時間對應用程序的使用非常重要。我正在使用計時器來執行動畫。我已經嘗試了常規清除直流電，使用不同的幀速率和雙緩衝，並且每次都得到相同的結果。

我的代碼如下：

import wx 
import os 

# begin wxGlade: extracode 
# end wxGlade 


class LbDisplay(wx.Frame): 
    sixon = False 
    sevenon = False 
    eighton = False 
    nineon = False 
    tenon = False 
    elevenon = False 
    ID_TIMER = 1 
    Speed = 1 
    red = 255 
    anim = 'down' 

    def __init__(self, *args, **kwds): 
     # begin wxGlade: LbDisplay.__init__ 
     kwds["style"] = wx.NO_BORDER | wx.NO_FULL_REPAINT_ON_RESIZE 
     wx.Frame.__init__(self, *args, **kwds) 
     self.timer = wx.Timer(self, LbDisplay.ID_TIMER) 
     self.button_6 = wx.Button(self, -1, "") 
     self.button_7 = wx.Button(self, -1, "") 
     self.button_8 = wx.Button(self, -1, "") 
     self.button_9 = wx.Button(self, -1, "") 
     self.button_10 = wx.Button(self, -1, "") 
     self.button_11 = wx.Button(self, -1, "") 
     self.button_11.Bind(wx.EVT_BUTTON, self.close) 
     self.button_6.Bind(wx.EVT_BUTTON, self.change_six) 
     self.Bind(wx.EVT_TIMER, self.blink, id=LbDisplay.ID_TIMER) 
     self.Bind(wx.EVT_PAINT, self.OnPaint) 

     self.__set_properties() 
     self.__do_layout() 

     # end wxGlade 

    def __set_properties(self): 
     # begin wxGlade: LbDisplay.__set_properties 
     self.SetTitle("LbDisplay") 
     # end wxGlade 

    def __do_layout(self): 
     # begin wxGlade: LbDisplay.__do_layout 

     self.SetMinSize(wx.GetDisplaySize()) 
     grid_sizer_1 = wx.GridSizer(6, 1, 0, 0) 
     grid_sizer_1.Add(self.button_6, 0, wx.EXPAND, 0) 
     grid_sizer_1.Add(self.button_7, 0, wx.EXPAND, 0) 
     grid_sizer_1.Add(self.button_8, 0, wx.EXPAND, 0) 
     grid_sizer_1.Add(self.button_9, 0, wx.EXPAND, 0) 
     grid_sizer_1.Add(self.button_10, 0, wx.EXPAND, 0) 
     grid_sizer_1.Add(self.button_11, 0, wx.EXPAND, 0) 
     self.SetSizer(grid_sizer_1) 
     grid_sizer_1.Fit(self) 
     self.Layout() 
     # end wxGlade 
    def change_six(self, e): 
     if LbDisplay.sixon == False: 
      LbDisplay.sixon = True 
      self.timer.Start(LbDisplay.Speed) 
     else: 
      self.button_6.SetBackgroundColour(wx.Colour(223, 220, 217, 0)) 
      self.timer.Stop() 
      LbDisplay.sixon = False 

    def close(self,e): 
     os._exit(True) 

    def blink(self,e): 
     if LbDisplay.anim == 'down': 
      LbDisplay.red -= 1 
      self.button_6.SetBackgroundColour(wx.Colour(LbDisplay.red,0,0)) 
      if LbDisplay.red <= 56: 
       LbDisplay.anim = 'up' 
     if LbDisplay.anim == 'up': 
      LbDisplay.red += 1 
      self.button_6.SetBackgroundColour(wx.Colour(LbDisplay.red,0,0)) 
      if LbDisplay.red >= 255: 
       LbDisplay.anim = 'down' 
    def OnPaint(self, e): 
     self.dc = wx.PaintDC(self) 




# end of class LbDisplay 
if __name__ == "__main__": 
    app = wx.PySimpleApp(0) 
    wx.InitAllImageHandlers() 
    LbDisplay = LbDisplay(None, -1, "") 
    app.SetTopWindow(LbDisplay) 
    LbDisplay.Show() 
    app.MainLoop() 

什麼想法？

我想出了我自己的想法。如果您觀察上面的代碼，您會注意到計時器正在使用300fps的刷新率。我甚至不認爲一個GPU可以做超過60fps的速度，而且這個速度是直接在CPU上運行的。大聲笑！ 把它降低到20fps的伎倆。現在它可以整天無故障運行。
