思路：
通过设置Panel的背景样式为wx.BG_STYLE_CUSTOM:
self.SetBackgroundStyle(wx.BG_STYLE_CUSTOM)
绑定Panel的背景事情：
self.Bind(wx.EVT_ERASE_BACKGROUND, self.OnEraseBackground)
在绑定方法中
bmp = wx.Bitmap("butterfly.jpg")
dc.DrawBitmap(bmp, 0, 0)
画出背景图片，从而实现给Panel容器添加背景图片
完整代码如下：
import wx ########################################################################
class MainPanel(wx.Panel):
"""""" #----------------------------------------------------------------------
def __init__(self, parent):
"""Constructor"""
wx.Panel.__init__(self, parent=parent)
self.SetBackgroundStyle(wx.BG_STYLE_CUSTOM)
self.frame = parent sizer = wx.BoxSizer(wx.VERTICAL)
hSizer = wx.BoxSizer(wx.HORIZONTAL) for num in range(4):
label = "Button %s" % num
btn = wx.Button(self, label=label)
sizer.Add(btn, 0, wx.ALL, 5)
hSizer.Add((1,1), 1, wx.EXPAND)
hSizer.Add(sizer, 0, wx.TOP, 100)
hSizer.Add((1,1), 0, wx.ALL, 75)
self.SetSizer(hSizer)
self.Bind(wx.EVT_ERASE_BACKGROUND, self.OnEraseBackground) #----------------------------------------------------------------------
def OnEraseBackground(self, evt):
"""
Add a picture to the background
"""
# yanked from ColourDB.py
dc = evt.GetDC() if not dc:
dc = wx.ClientDC(self)
rect = self.GetUpdateRegion().GetBox()
dc.SetClippingRect(rect)
dc.Clear()
bmp = wx.Bitmap("butterfly.jpg")
dc.DrawBitmap(bmp, 0, 0) ########################################################################
class MainFrame(wx.Frame):
"""""" #----------------------------------------------------------------------
def __init__(self):
"""Constructor"""
wx.Frame.__init__(self, None, size=(600,450))
panel = MainPanel(self)
self.Center() ########################################################################
class Main(wx.App):
"""""" #----------------------------------------------------------------------
def __init__(self, redirect=False, filename=None):
"""Constructor"""
wx.App.__init__(self, redirect, filename)
dlg = MainFrame()
dlg.Show() #----------------------------------------------------------------------
if __name__ == "__main__":
app = Main()
app.MainLoop()
可以尝试运行一下 :)
