I have been hitting a dead end with this program. I am trying to build a class that will let me control the BIP's of a button when it is in use. so far this is what i have (see following.) It keeps running this weird error TypeError: 'module' object is not callable - I, coming from C++ and C# (for some reason the #include... is so much easier) , have no idea what that means, Google is of no help so... I know I need some real help with sintax and such - anything woudl be helpful.

Note: The base code found here was used to create a skeleton for this 'custom button class'

Custom Button

import wx
from wxPython.wx import *

class Custom_Button(wx.PyControl):

                                    # The BMP's
# AM I DOING THIS RIGHT? - I am trying to get empty 'global' 
# variables within the class
    Mouse_over_bmp = None #wxEmptyBitmap(1,1,1)   # When the mouse is over
    Norm_bmp = None #wxEmptyBitmap(1,1,1)         # The normal BMP
    Push_bmp = None #wxEmptyBitmap(1,1,1)         # The down BMP

    Pos_bmp = wx.Point(0,0)         # The posisition of the button

    def __init__(self, parent, NORM_BMP, PUSH_BMP, MOUSE_OVER_BMP,
                 pos, size, text="", id=-1, **kwargs):
        wx.PyControl.__init__(self,parent, id, **kwargs)

# The conversions, hereafter, were to solve another but. I don't know if it is 
# necessary to do this since the source being given to the class (in this case)
# is a BMP - is there a better way to prevent an error that i have not
# stumbled accost? 

        # Set the BMP's to the ones given in the constructor
        self.Mouse_over_bmp = wx.Bitmap(wx.Image(MOUSE_OVER_BMP, wx.BITMAP_TYPE_ANY).ConvertToBitmap())
        self.Norm_bmp = wx.Bitmap(wx.Image(NORM_BMP, wx.BITMAP_TYPE_ANY).ConvertToBitmap())
        self.Push_bmp = wx.Bitmap(wx.Image(PUSH_BMP, wx.BITMAP_TYPE_ANY).ConvertToBitmap())
        self.Pos_bmp = self.pos

        self.Bind(wx.EVT_LEFT_DOWN, self._onMouseDown)
        self.Bind(wx.EVT_LEFT_UP, self._onMouseUp)
        self.Bind(wx.EVT_LEAVE_WINDOW, self._onMouseLeave)
        self.Bind(wx.EVT_ENTER_WINDOW, self._onMouseEnter)
        self.Bind(wx.EVT_ERASE_BACKGROUND,self._onEraseBackground)
        self.Bind(wx.EVT_PAINT,self._onPaint)

        self._mouseIn = self._mouseDown = False

    def _onMouseEnter(self, event):
        self._mouseIn = True

    def _onMouseLeave(self, event):
        self._mouseIn = False

    def _onMouseDown(self, event):
        self._mouseDown = True

    def _onMouseUp(self, event):
        self._mouseDown = False
        self.sendButtonEvent()

    def sendButtonEvent(self):
        event = wx.CommandEvent(wx.wxEVT_COMMAND_BUTTON_CLICKED, self.GetId())
        event.SetInt(0)
        event.SetEventObject(self)
        self.GetEventHandler().ProcessEvent(event)

    def _onEraseBackground(self,event):
        # reduce flicker
        pass

    def _onPaint(self, event):
        dc = wx.BufferedPaintDC(self)
        dc.SetFont(self.GetFont())
        dc.SetBackground(wx.Brush(self.GetBackgroundColour()))
        dc.Clear()
        dc.DrawBitmap(self.Norm_bmp)

        # draw whatever you want to draw
        # draw glossy bitmaps e.g. dc.DrawBitmap
        if self._mouseIn:   # If the Mouse is over the button
            dc.DrawBitmap(self, self.Mouse_over_bmp, self.Pos_bmp, useMask=False)
        if self._mouseDown: # If the Mouse clicks the button
            dc.DrawBitmap(self, self.Push_bmp, self.Pos_bmp, useMask=False)

Main.py

import wx
import Custom_Button
from wxPython.wx import *

ID_ABOUT = 101
ID_EXIT  = 102

class MyFrame(wx.Frame):
    def __init__(self, parent, ID, title):
        wxFrame.__init__(self, parent, ID, title,
                         wxDefaultPosition, wxSize(400, 400))

        self.CreateStatusBar()
        self.SetStatusText("Program testing custom button overlays")
        menu = wxMenu()
        menu.Append(ID_ABOUT, "&About", "More information about this program")
        menu.AppendSeparator()
        menu.Append(ID_EXIT, "E&xit", "Terminate the program")
        menuBar = wxMenuBar()
        menuBar.Append(menu, "&File");
        self.SetMenuBar(menuBar)

        self.Button1 = Custom_Button(self, parent, -1, 
                                "D:/Documents/Python/Normal.bmp", 
                                "D:/Documents/Python/Clicked.bmp",
                                "D:/Documents/Python/Over.bmp",
                                wx.Point(200,200), wx.Size(300,100))

        EVT_MENU(self, ID_ABOUT, self.OnAbout)
        EVT_MENU(self, ID_EXIT,  self.TimeToQuit)

    def OnAbout(self, event):
        dlg = wxMessageDialog(self, "Testing the functions of custom "
                              "buttons using pyDev and wxPython",
                              "About", wxOK | wxICON_INFORMATION)
        dlg.ShowModal()
        dlg.Destroy()


    def TimeToQuit(self, event):
        self.Close(true)



class MyApp(wx.App):
    def OnInit(self):
        frame = MyFrame(NULL, -1, "wxPython | Buttons")
        frame.Show(true)
        self.SetTopWindow(frame)
        return true

app = MyApp(0)
app.MainLoop()

Errors (and traceback)

/home/wallter/python/Custom Button overlay/src/Custom_Button.py:8: DeprecationWarning: The wxPython compatibility package is no longer automatically generated or actively maintained.  Please switch to the wx package as soon as possible.

I have never been able to get this to go away whenever using wxPython any help?

  from wxPython.wx import *
Traceback (most recent call last):
  File "/home/wallter/python/Custom Button overlay/src/Main.py", line 57, in <module>
    app = MyApp(0)
  File "/usr/lib/python2.6/dist-packages/wx-2.8-gtk2-unicode/wx/_core.py", line 7978, in __init__
    self._BootstrapApp()
  File "/usr/lib/python2.6/dist-packages/wx-2.8-gtk2-unicode/wx/_core.py", line 7552, in _BootstrapApp
    return _core_.PyApp__BootstrapApp(*args, **kwargs)
  File "/home/wallter/python/Custom Button overlay/src/Main.py", line 52, in OnInit
    frame = MyFrame(NULL, -1, "wxPython | Buttons")
  File "/home/wallter/python/Custom Button overlay/src/Main.py", line 32, in __init__
    wx.Point(200,200), wx.Size(300,100))
TypeError: 'module' object is not callable

I have tried removing the "wx.Point(200,200), wx.Size(300,100))" just to have the error move up to the line above. Have I declared it right? help?
