# used to listen to the application events and also the events for a custom button
import ctypes
import win32com.client
from win32com.client.gencache import EnsureDispatch
import pythoncom
 
class Events():
    def __init__(self, oApp):
        global Application
        Application = oApp
   
    #Application Events
    class IVEvent():      
        def OnQuit(self, BeforeOrAfter, Context, HandlingCode):
            print("Quiting...")
            ctypes.windll.user32.PostQuitMessage(0)
            Application.Quit()
     
    #Custom Button Events      
    class BEvent():
        def OnExecute(self, Context):
            print "Dxf Button Clicked"
 
class DoylePlugin():    
    oApp=EnsureDispatch("Inventor.Application")
    oApp.Visible=True
      
    DxfButton=oApp.CommandManager.ControlDefinitions.AddButtonDefinition("Dxf Update", "dxf", 4)
    DxfButton.AutoAddToGUI()
    
    Events = Events(oApp)        
    AppEvents=win32com.client.DispatchWithEvents(oApp.ApplicationEvents, Events.IVEvent)

My prefered Python IDE

My prefered Python editor is Pyscripter from MMExperts. It is not only an editor. Pyscripter is a full Python IDE including (remote) debugging, a class browser, and all other nice helpers which a full featured IDE needs.

Do you have a script for me ?

Do you have an interesting Python script which does some really cool thing on Windows ? Please post them to this site. It`s very simple - simply copy&paste it to this form. No login is requiered.

Hint: For syntax highlighting and correct Python intendation place your code between html tags <pre> and </pre>.

My prefered web framework

My prefered web framework for developing web applications is Django. Django calls itself The web framework for perfectionists with deadlines. It is a really fast, scalable and (thanks Python) the sexiest web framework of the world.
