get_tree() in shell.appSystem

[rastersoft <raster rastersoft com>]

Hi all:

I have a gnome shell extension that adds an app menu. Until now I used 
the get_tree() method in the object returned by 
shell.appSystem.get_default() to get all the currently installed apps, 
but that method is not available in gnome shell 3.12. How can I replace it?

Thanks.
