I'm struggling to learn how Thunderbird extension works but I'm stuck by the lack of documentation. Inside an extension I found:
gFolderTreeView._modeNames...
...
gFolderTreeView.getFolderTreeMode(viewName);
Google gives no help in trying to understand something more about gFolderTreeView. I can only find examples where it is used but no API description. Where can I find the list of its methods, properties and a description of what they do ?
