Question

如何将背景图像添加到panel1？有哪个命令？

代码：

import wx
import wx
appy=wx.App()

class cg(wx.Frame) :
     def __init__(self,parent,id) :
         wx.Frame.__init__(self,parent,id,'GPA',pos=(1000,600),size=(600,400))
         #splitter = wx.SplitterWindow(self, -1)
         panel1 = wx.Panel(self)
         panel2 = wx.Panel(panel1, -1,size=(600,200),style=wx.BORDER_SUNKEN)
         panel3 = wx.Panel(panel1, -1,pos=(0,200),size=(600,200),style=wx.BORDER_SUNKEN)
         #panel3=wx.panel(panel1,-1,pos=(300,200),size=(600,200),style=wx.BORDER_SUNKEN)
         #panel13 = wx.Panel(panel1, -1, style=wx.BORDER_SUNKEN)
         #panel13 = wx.Panel(panel1, -1, style=wx.BORDER_SUNKEN)
         #panel13 = wx.Panel(panel1, -1, style=wx.BORDER_SUNKEN)

         #button1=wx.Button(panel1,label='exit',pos=(10,10),size=(10,10))
         #self.cnt1=wx.TextCtrl(panel1,pos=(40,60),size=(120,30))

if __name__=='__main__' :

     app=wx.PySimpleApp()
     frame=cg(parent=None,id=-1)
     frame.Show()
     app.MainLoop()
