下面的代码应该在点击一个按钮时播放一些gif图像。当点击另一个按钮时播放另一个gif图像。但是当我点击第一个按钮时它正在播放相关的图像正确.. 虽然通过点击第二个按钮,第一个图像和第二个无限循环一个接一个地播放 ...所以如何通过按钮点击播放一个gif?wxpython逐个显示gif图像

import wx, wx.animate 

class MyForm(wx.Frame): 

    #---------------------------------------------------------------------- 
    def __init__(self): 
     wx.Frame.__init__(self, None, wx.ID_ANY) 

     panel = wx.Panel(self, wx.ID_ANY) 
     btn1 = wx.Button(self, -1, "play GIF 1",(50,10)) 
     btn1.Bind(wx.EVT_BUTTON, self.onButton1) 

     btn2 = wx.Button(self, -1, "play GIF 2",(50,40)) 
     btn2.Bind(wx.EVT_BUTTON, self.onButton2) 

    #---------------------------------------------------------------------- 
    def onButton1(self, event): 
     image='animated_1.gif' 
     self.animateGIF(image) 

    #---------------------------------------------------------------------- 
    def onButton2(self, event): 
     image='animated_2.gif' 
     self.animateGIF(image) 

    #---------------------------------------------------------------------- 
    def animateGIF(self,image): 
     gif = wx.animate.GIFAnimationCtrl(self, -1, image,pos=(50,70),size=(10,10)) 
     gif.GetPlayer() 
     gif.Play() 
#---------------------------------------------------------------------- 
app = wx.App() 
frame = MyForm().Show() 
app.MainLoop()

您需要停止并销毁之前的gif图像,然后再开始新图像。就像这样:

import wx, wx.animate 

class MyForm(wx.Frame): 

    #---------------------------------------------------------------------- 
    def __init__(self): 
     wx.Frame.__init__(self, None, wx.ID_ANY) 

     panel = wx.Panel(self, wx.ID_ANY) 
     btn1 = wx.Button(self, -1, "play GIF 1",(50,10)) 
     btn1.Bind(wx.EVT_BUTTON, self.onButton1) 

     btn2 = wx.Button(self, -1, "play GIF 2",(50,40)) 
     btn2.Bind(wx.EVT_BUTTON, self.onButton2) 

     self.gif = None 

    #---------------------------------------------------------------------- 
    def onButton1(self, event): 
     image='animated_1.gif' 
     self.animateGIF(image) 

    #---------------------------------------------------------------------- 
    def onButton2(self, event): 
     image='animated_2.gif' 
     self.animateGIF(image) 

    #---------------------------------------------------------------------- 
    def animateGIF(self,image): 
     if self.gif: 
      self.gif.Stop() 
      self.gif.Destroy() 

     self.gif = wx.animate.GIFAnimationCtrl(self, -1, image,pos=(50,70),size=(10,10)) 
     self.gif.GetPlayer() 
     self.gif.Play() 
#---------------------------------------------------------------------- 
app = wx.App() 
frame = MyForm().Show() 
app.MainLoop() 

我加self.gif = None__init__功能和变化不大的功能animateGIF
