如何使用python在执行wx.BusyInfo()函数后弹出的界面中显示gif动画

可以使用wx.animate.GIFAnimationCtrl控件来实现在wx.BusyInfo弹出界面中显示gif动画。首先，需要使用wx.animate.Animation类的Load()方法将.gif文件加载进来，并使用wx.animate.AnimationCtrl类的Start()方法来播放动画。然后，将wx.animate.AnimationCtrl对象添加到wx.BusyInfo弹出的对话框中即可。以下是示例代码：

import wx
import wx.animate

app = wx.App()

# create a parent window
parent_frame = wx.Frame(None, title="Parent Window")
parent_frame.Center()
parent_frame.Show()

# create a busy info dialog
busy_dlg = wx.BusyInfo("Please wait, loading...")

# create a gif animation control
gif = wx.animate.Animation()
gif.Load("my_animation.gif")
gif_ctrl = wx.animate.AnimationCtrl(parent_frame, wx.ID_ANY, gif)
gif_ctrl.Play()

# add the gif animation control to the busy info dialog
bmp = gif_ctrl.GetAnimation()
busy_dlg.SetIcon(wx.IconFromBitmap(bmp))
busy_dlg.Update()

# do something here that takes time

# destroy the busy info dialog and stop the gif animation
del busy_dlg
gif_ctrl.Stop()
gif_ctrl.Destroy()

app.MainLoop()
