我正在尝试向wxpython静态位图添加“value”属性，但我无法想象如何实例化我创建的子类。当我尝试创建它时，我收到错误'期望一个2元组的整数或一个wxPoint对象。'
任何人都可以告诉我缺少什么吗？
由于
class StaticBmpButton(wx.StaticBitmap):
def __init__(self, parent,id,bmp_off,bmp_on,bmp_over):
super(wx.StaticBitmap,self).__init__(parent,id,bitmap)
self.value=False
答案 0 :(得分：0)
听起来你正在创建自己的自定义按钮？您可能希望将其创建为PyControl。我使用这种方法创建了一个fadebutton，可以将其作为自定义控件导入并直接替换为wx.Button。
class StaticBmpButton(wx.PyControl):
def __init__(self, parent, id=wx.ID_ANY, label="", pos=wx.DefaultPosition, size=wx.DefaultSize, style=wx.NO_BORDER, validator=wx.DefaultValidator, name="StaticBmpButton"):
wx.PyControl.__init__(self, parent=parent, id=id, pos=pos, size=size, style=wx.NO_BORDER, validator=validator, name=name)
以下是自定义PyContol按钮基本框架的链接： http://www.python-forum.org/pythonforum/viewtopic.php?f=2&t=17567 我现在无法加载python-forum。如果您需要我发布该页面的代码，请告诉我。
编辑：我猜python-forum不再存在了。这是缓存页面的链接： http://cc.bingj.com/cache.aspx?q=BlockButton.py+gradient&d=4580007883572708&mkt=en-US&setlang=en-US&w=7g-uOMgExcAivyB_VE3bzv2kstr-ww21
编辑以显示示例：
这只是一个如何在PyControl框架中使用位图的简单示例。可能有更好的方法来做到这一点，但它会告诉你这个想法。对不起，代码太长了，但我想嵌入图片，以便更容易演示。

感谢GolfDope的评论和解决方案。但我正在寻找的是一种使用wxPython的内置小部件的方法。
在搜索了大量的问题和答案之后，看起来我需要的是GenStaticBitmap。它看起来像这样，并做我需要的。如果它证明不够强大，我将被迫用上面的PyControl做一些事情。 这似乎有用：
import wx.lib.statbmp as gen_statbmp
# (gen_statbmp.GenStaticBitmap).__init__(self, parent, ID, bitmap, pos, size, style, name)
########################################################################
class MyBitmapButton(gen_statbmp.GenStaticBitmap):
"""Subclasses a GenStaticBitmap and adds button like functionality
requires the three bitmap images needed for on,off and hover"""
#----------------------------------------------------------------------
def __init__(self, parent, ID, bmpoff,bmpon,bmphover):
"""Constructor"""
gen_statbmp.GenStaticBitmap.__init__(self, parent, ID, bmpoff)
self.bmpoff=bmpoff
self.bmpon=bmpon
self.bmphover=bmphover
self.SetBitmap(bmpoff)
self.state='off'
# Bind Mouse Actions to button
self.Bind(wx.EVT_ENTER_WINDOW,self.On_Hover)
self.Bind(wx.EVT_LEAVE_WINDOW,self.On_Leave)
self.Bind(wx.EVT_LEFT_DOWN,self.On_Click)
# Define Mouse Actions and Button Response
def On_Hover(self,event):
self.SetBitmap(self.bmphover)
def On_Leave(self,event):
#print 'on enter button state is',self.state
if self.state=='on':
self.SetBitmap(self.bmpon)
self.state='on'
if self.state=='off':
self.SetBitmap(self.bmpoff)
self.state='off'
#print 'on leave button state is',self.state
def On_Click(self,event):
self.SetBitmap(self.bmpon)
event.Skip()
