function takes at least 2 arguments

Question

I'm using a python script for xbmc program, I can open addons.py without have any problem, but I can't be able to open test.py from addons.py. I'm currently using the code on two different files addons.py and test.py.

Addons.py:

import xbmcgui
import xbmcaddon
import buggalo
from test import MyClass

buggalo.SUBMIT_URL = 'http://tommy.winther.nu/exception/submit.php'

try:
    w = xbmcgui.WindowXML( "script-tvguide-mainmenu.xml", xbmcaddon.Addon().getAddonInfo('path'), "Default" )
    w.doModal()
    del w
    print 'Hello!'

    mydisplay = MyClass()
    mydisplay.doModal()

except Exception:
    buggalo.onExceptionRaised()

test.py:

print "hello!"
import xbmc 
import xbmcgui

#get actioncodes from https://github.com/xbmc/xbmc/blob/master/xbmc/guilib/Key.h
ACTION_MOVE_LEFT = 1
ACTION_MOVE_RIGHT = 2
ACTION_MOVE_UP = 3
ACTION_MOVE_DOWN = 4

class MyClass(xbmcgui.WindowXML):
  def onAction(self, action):
    if action == ACTION_MOVE_LEFT:
      print "You have press on the left arrow button!"
      self.close()

    if action == ACTION_MOVE_RIGHT:
      print "You have press on the right arrow button!"
      self.close()

    if action == ACTION_MOVE_UP:
      print "You have press on the up arrow button!"
      self.close()

    if action == ACTION_MOVE_DOWN:
      print "You have press on the down arrow button!"
      self.close()

I really need your help because when I open the addons.py, I can't be able to open the test.py from addons.py. It will give me an error of function takes at least 2 arguments (0 given). I don't know what to do.

Here is the log: http://pastebin.com/Qacy0UnA

Does anyone know how I can open the test.py from addons.py script?

On what line does that error occur? Can you please post the entire traceback? Also, what does "open" mean? Do you mean "import" or "run"? Finally, I would bet the problem is because the line `w.doModal()` - the function `doModal()` requires 2 arguments, but you have given it zero (place the arguments between the parentheses, like `w.doModal(arg1,arg2)`). — darthbith, Jan 07 '14 at 17:23

Dig up the docs for xbmcgui.WindowXML and see what the constructor arguments are.

thank you very much for your advice. I have looked the docs for `xbmcgui.WindowXML`, so I have replaced `MyClass(xbmcgui.WindowXMLDialog)` from `MyClass(xbmcgui.WindowXML)` which it have got rid of the error. I have a little problem, when I use `print` on xbmc, it did not display on the screen. Do you know why? – Jan 07 '14 at 17:44
xbmc probably have their own function for sending text to the screen. – M4rtini Jan 07 '14 at 17:49
How I can see the text to the screen using print? – Jan 07 '14 at 18:07
No idea, a new question might attract someone more familiar with the xbmcgui api. – M4rtini Jan 07 '14 at 18:15
http://wiki.xbmc.org/index.php?title=HOW-TO:Write_Python_Scripts_for_XBMC Looks like you need to be in debug mode. – M4rtini Jan 07 '14 at 18:36

Change

mydisplay = MyClass()

to

mydisplay = MyClass("script-tvguide-mainmenu.xml", xbmcaddon.Addon().getAddonInfo('path'))

This is because WindowXML, the superclass of MyClass, takes two arguments, filename and path. It is very well defined in http://mirrors.xbmc.org/docs/python-docs/stable/xbmcgui.html#WindowXML

thank you very much for this, but when I select on the main menu button, it will display the background. When i press on the up,down,left or right arrow button on the keyboard it will close and return to the main menu. Do you have any idea why? – Jan 07 '14 at 17:50
Just realised that I'm using the 'self.close' which it will close and return to the main menu. Do you know how I can display the dialog box when I press on the up, down, left and right arrow buttons of the keyboard? because when I try to use print "hello world!", nothing will show on my screen. – Jan 07 '14 at 17:54
Please explain the reason why your answer would work. – Bleeding Fingers Jan 07 '14 at 18:03
@chrisoojer Just call whatever method is used for showing the dialog box instead of `self.close`. `print` is writing to standard output so you'll probably have to look in a log or console to see that message. – Mattias Jan 07 '14 at 18:32
