Title: Help With Ooba Multi Browser Script
Post by: Phunck on April 07, 2005, 04:49:00 AM

I'm having trouble with seemingly random chrashes of this script i'm making... The weird thing is that these chrases only occurs when i'm running the script on the xbox not when i'm running it on the emulator by alexpoet.

Another thing i'm trying is to use a ControlTextBox for displaying progess information (see the OpenUrl function). But it does not work ... It seems to me that the gui is not being updated while the script is running. Is there anyway of forcing a redraw of the screen?




OOBA.PY:
Note if you try out the code you'll need to copy lyricspanel.png to the same folder as this script and create a cache subfolder also. Note this is my first python script ever so excuse any weirdness, but feel free to give advice :-).

CODE

# ScriptName   : ooba.py   (Browse using RegExp's, couldn't think of a good name)
# Version   : 0.1 beta
# Author   : Van der Phunck aka Aslak Grinsted. [email protected] <- not cmo but com
# Desc  : flexible browser for streams,images and rawtext.
#
# Based on many scripts but primarily GameSpotPlus & XBMCLyrics.
#
#
# My ambition with this script is that you can give it a list of urls and tell it
# what it should do with "that kind of url".
#
# E.g. mp3,pls&avi files should be played, jpg should be shown and
# http://www.bbc.co.uk/radio/aod/index_choose.shtml should result in a sub menu.
#
#
#
#
#
#
# Version 0.1 beta
# Initial Release
