[Tutor] finding path to resource files in a GUI application

Hi
Currently I'm writing a GUI application with wxPython (on OS X, but I
guess the problem is the same, regardless of the UNIX derivative one is
using). When I start the main script where it is located the
application finds all resource files (non-Python files like images and
html files for html windows) without any problem. However, if a put a
link in /usr/local/bin and start the script using the link the
application cannot find those resource files - unless, of course, I
will use full absolute paths to point to those files. One brief example
to illustrate the problem:
The class Goals is in a file called Help.py, located in '/gui_lib/' as
seen from my main script.
class Goals(wx.Frame):
def __init__(self,parent,frame,title,size,pos=wx.DefaultPosition):
wx.Frame.__init__(self,parent,
-1,title,size,style=wx.DEFAULT_FRAME_STYLE)
self.frame = frame
self.cwd = os.getcwd()
self.html = HtmlWindow(self,-1)
self.html.LoadPage(os.path.join(self.cwd,'gui_lib/Goals.html'))
#this, of course, won't work
#if the main script is called from somewhere else and not the
directory where the main script
#is located
Any ideas what I could use instead of os.getcwd to construct a relative
path which will work even if I port the script to an other machine?
Cheers
Christian
