Python - help on custom wx.Python (pyDev) class
- by Wallter
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)

I have never been able to get this to go away whenever using wxPython any help?
from wxPython.wx import *

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?
