View Full Version : Issue with having icon for a python program

April 24th, 2009, 07:40 AM
I have a python program I've worked on with a group, and I'm trying to create a .deb package for it. The program consists of two .py files and an icon files. To run the program I run one .py file, which uses the other two files. I was successful in creating the .deb file (thanks to the guide on here) but when I try to include a shortcut in the gnome menu for the program that executes:
python "/opt/treelink/TreeLink.py"
The program will start with the error message:
Can't load image from file 'treelink_icon.ico': file does not exist.
but otherwise runs normally (except for the lack of an icon)

The icon is implemented like this in the code (using wxpython):
iconFile = "treelink_icon.ico"
icon = wx.Icon(iconFile, wx.BITMAP_TYPE_ICO)

This is the same error I get if I am in terminal, and not in the current working directory of the program files, and then attempt to execute the program by providing the path the file (i.e. python /path/to/file/file.py ).

How can I fix this error? Is it simply a matter of putting the icon file in the right directory (right now everything gets put in a folder in the /opt directory upon install)? Or is it some change I need to make to the code (in which case I would preferably like to make this change in a way that keeps it cross-platform).

The quick and dirty way (assuming the icon and py file are in the same directory or the icon file is in a directory off that directory) is to use

To return the directory that you py file is in and then append the icon file name using os.path.join

Building on ajackson's suggestion, perhaps:

Thanks. I went with the join option and it worked well (although the chdir trick is also a neat idea).
