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 :)
