wxPython : Adding an about box.

I'm creating a wxPython soundboard and was wondering how to implement an About Box. The goal is to press an About button on the wxPython File menu and generate an About Box.
This is my code so far:
import wx
import os
import pygame
pygame.init()
##SOUNDS##
goliathwav = pygame.mixer.Sound("goliath.wav")
channelopen = pygame.mixer.Sound("channelopen.wav")
##SOUNDS##
class windowClass(wx.Frame):
def __init__(self, *args, **kwargs):
super(windowClass,self).__init__(*args,**kwargs)
self.__basicGUI()
def __basicGUI(self):
panel = wx.Panel(self)
menuBar = wx.MenuBar()
fileButton = wx.Menu()
editButton = wx.Menu()
aboutBox = wx.MessageDialog(None, "Created by Kommander000(cyrex)")
answer=aboutBox.ShowModal()
aboutBox.Destroy()
aboutButton = wx.Menu()
exitItem = fileButton.Append(wx.ID_EXIT, 'Exit','status msg...')
aboutItem = aboutButton.Append(wx.ID_ABOUT, "About")
menuBar.Append(fileButton, 'File')
menuBar.Append(editButton, 'Edit')
menuBar.Append(aboutButton, 'About this program')
self.SetMenuBar(menuBar)
self.Bind(wx.EVT_MENU, self.__quit, exitItem)
self.Bind(wx.EVT_MENU, self.OnMenuHelpAbout, aboutBox)
self.__sound_dict = { "Goliath" : "goliath.wav",
"Goliath2" : "channelopen.wav"
}
self.__sound_list = sorted(self.__sound_dict.keys())
self.__list = wx.ListBox(panel,pos=(20,20), size=(250,150))
for i in self.__sound_list:
self.__list.Append(i)
self.__list.Bind(wx.EVT_LISTBOX,self.__on_click)
#wx.TextCtrl(panel,pos=(10,10), size=(250,150))
self.SetTitle("Soundboard")
self.Show(True)
def __on_click(self,event):
event.Skip()
name = self.__sound_list[self.__list.GetSelection()]
filename = self.__sound_dict[name]
if filename == "goliath.wav":
print "[ NOW PLAYING ] ... %s" % filename
pygame.mixer.Sound.play(goliathwav)
if filename == "channelopen.wav":
print "[ NOW PLAYING ] ... %s" % filename
pygame.mixer.Sound.play(channelopen)
def __quit(self, e):
self.Close()
def main():
app = wx.App()
windowClass(None, -1, style=wx.MAXIMIZE_BOX | wx.CAPTION | wx.CENTRE)
app.MainLoop()
main()
This is the error I am receiving:
self.Bind(wx.EVT_MENU, self.OnMenuHelpAbout, aboutBox)
AttributeError: 'windowClass' object has no attribute 'OnMenuHelpAbout'
Any suggestions?
Thanks as always,
kommander000

wx python has its own wx.AboutBox() used in conjunction with wx.AboutDialogInfo()
def About(self, event):
from platform import platform
myos = platform()
aboutInfo = wx.AboutDialogInfo()
aboutInfo.SetName("My Application ")
aboutInfo.SetVersion("1.0")
aboutInfo.SetDescription("My Super App," \
" That does amazing things\nRunning on: "+myos)
aboutInfo.SetCopyright("(C) Joe Bloggs-2016")
aboutInfo.SetLicense("https://www.gnu.org/licenses/gpl-2.0.html")
aboutInfo.AddDeveloper("Joe Bloggs")
aboutInfo.AddDocWriter("Joe Bloggs")
aboutInfo.SetWebSite('https://www.JoeBlogs.com')
wx.AboutBox(aboutInfo)
See:https://wxpython.org/docs/api/wx-module.html#AboutBox

you again :)
The aboutBox needs to be created in your missing callback OnMenuHelpAbout (that I refactored to make private as stated in my previous answer)
Also (not related) but I have changed the dictionary so it directly points to the sound object: no more if/elif, you can load 200 sounds the code will still be the same.
Fixed code:

import os
import pygame
pygame.init()

MplayerCtrl - MPlayer on Mac with WxPython

I am trying to get a simple media player working (scipt below) on Python 2.7.11, Wxpython, with MplayerCtrl on Mac 10.11.4, I just compiled the latest MPlayer 1.3.0, but when opening an mp4 video file I get the below error message, Mplayer opens independently (not in the player window) and also XQuartz opens for some reason, heres the error message:
Traceback (most recent call last):

Simple wxPython post event from Process

I am trying to create a window that receives simple event notifications from a Process. Here is the code that I have so far:
import wx, wx.lib.newevent, time, sys
from multiprocessing import Process
size_width = 320
size_height = 240
background_color = (226,223,206)
SomeNewEvent, EVT_SOME_NEW_EVENT = wx.lib.newevent.NewEvent()
class StatusWindow(wx.Frame):
def __init__(self, parent):
super(StatusWindow, self).__init__(parent, title='Monitor', size=(size_width, size_height))
self.Bind(EVT_SOME_NEW_EVENT, self.updateStatus)
staticBox = wx.StaticBox(self, label='Monitor Status:', pos=(5, 105), size=(size_width - 28, size_height/3))
self.statusLabel = wx.StaticText(staticBox, label='None', pos=(10, 35), size=(size_width, 20), style=wx.ALIGN_LEFT)
self.count = 0
self.InitUI()
self.monitor = cMonitor()
self.monitor.start()
def InitUI(self):
panel = wx.Panel(self)
self.SetBackgroundColour(background_color)
self.Centre()
self.Show()
def updateStatus(self, evt):
self.statusLabel.SetLabel(evt.attr1)
class cMonitor(Process):
def __init__(self):
super(cMonitor, self).__init__()
def run(self):
time.sleep(2)
print 'This is an update'
#create the event
evt = SomeNewEvent(attr1="Some event has just occured")
#post the event
wx.PostEvent(EVT_SOME_NEW_EVENT, evt)
if __name__ == '__main__':
app = wx.App()
window = StatusWindow(None)
app.MainLoop()
The window gets created, but the Process does not appear to be either executing or sending the post event notification correctly. I should note that the print statement in the run method is not showing up either. What is causing the GUI to not be updated?? This was what I used as a reference:
http://wiki.wxpython.org/CustomEventClasses

First of all, your code throws an error:
Traceback (most recent call last):
File "C:\Python27\lib\multiprocessing\process.py", line 232, in _bootstrap
self.run()
File "C:\PyProgs\stackoverflow_answers\wx_answers\wx_events1.py", line 44, in run
wx.PostEvent(EVT_SOME_NEW_EVENT, evt)
File "C:\Python27\lib\site-packages\wx-3.0-msw\wx\_core.py", line 8410, in PostEvent
return _core_.PostEvent(*args, **kwargs)
TypeError: in method 'PostEvent', expected argument 1 of type 'wxEvtHandler *'
According the docs, PostEvent(dest, event) send an event to a window or other wx.EvtHandler to be processed later, but in your code first parameter has type PyEventBinder. Your code would have to look something like this:
wx.PostEvent(self.wxWindow, evt)
where self.wxWindow - object of StatusWindow class. But there is another problem: you can not use wxPython objects as multiprocessor arguments(link).
One way to do what you want - using threading module instead multiprocessing:
import wx, wx.lib.newevent, time, sys
from threading import *
size_width = 320
size_height = 240
background_color = (226,223,206)
SomeNewEvent, EVT_SOME_NEW_EVENT = wx.lib.newevent.NewEvent()
class StatusWindow(wx.Frame):
def __init__(self, parent):
super(StatusWindow, self).__init__(parent, title='Monitor', size=(size_width, size_height))
self.Bind(EVT_SOME_NEW_EVENT, self.updateStatus)
staticBox = wx.StaticBox(self, label='Monitor Status:', pos=(5, 105), size=(size_width - 28, size_height/3))
self.statusLabel = wx.StaticText(staticBox, label='None', pos=(10, 35), size=(size_width, 20), style=wx.ALIGN_LEFT)
self.count = 0
self.InitUI()
# Set up event handler for any worker thread results
self.monitor = cMonitor(self)
self.monitor.start()
def InitUI(self):
panel = wx.Panel(self)
self.SetBackgroundColour(background_color)
self.Centre()
self.Show()
def updateStatus(self, evt):
self.statusLabel.SetLabel(evt.attr1)
class cMonitor(Thread):
def __init__(self, wxWindow):
super(cMonitor, self).__init__()
self.wxWindow = wxWindow
def run(self):
time.sleep(2)
print 'This is an update'
#create the event
evt = SomeNewEvent(attr1="Some event has just occured")
#post the event
wx.PostEvent(self.wxWindow, evt)
if __name__ == '__main__':
app = wx.App()
window = StatusWindow(None)
app.MainLoop()

Don't call threading.Thread._Thread__stop! The leading underscore is a sign that this is internal api, it's not guaranteed to even exist (in fact, in python3 it's gone).
If you wish the thead to be destroyed automatically, set it to be daemonic:
def __init__(self):
super(screenshot_thread, self).__init__()
self.daemon = True
That will cause it to be automatically destroyed when the last non-daemonic thread has stopped. Or, in your case, just setting the state to False should make the thread exit after 10 seconds.

You defined a stop method in your screenshot_thread class but you does not use it. Calling it in the method OnCloseWindow should do the job.

It may be that I didn't install wx correctly. I am using Python 2.4 and I was unable to find the wx module for Python 2.4. I downloaded wx for Python 2.5 and pasted the wx folder into the Python 2.4 directory. Can you please guide me how to add the wx module in Python 2.4?

Check here.
The 2.8.10 version still has binary installers for 2.4
