您可以在面板上设置背景图像,然后使用 wx.StaticBitmap 小部件将其他图像放在它上面。我写了一篇关于如何在 wx.Panel 上放置背景图片的教程:http: //www.blog.pythonlibrary.org/2010/03/18/wxpython-putting-a-background-image-on-a-panel /
这是我教程中的代码:
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()
现在您只需将按钮换成 StaticBitmap 小部件。
