[erlang-questions] wxErlang question 4

[Steve Davis]

I see why. You can either:

1) rename the parent directory to “gx” rather than “gx-master” 
2) or edit the path attribute in priv/ide.xml line 41 <filetree id="filetree" fill="both" path="../gx" onclick="on_tree" ondblclick="on_tree" onchange="on_tree”>  change it to a valid directory (e.g. ../gx-master in your case)...

...and it should work.



When I left it, I was using the editor to hack the code itself…

Alternatively set the path
