Porting Global-AppMenu

["Anibal F. Martinez Cortina" <linuxkid zeuz gmail com>]

Hey everyone, I've been trying to port Global-AppMenu from Cinnamon to Gnome-Shell.

In trying to port it, I've come across configurableMenus, in wich class ConfigurableMenuu extends PopupMenu.PopupMenu.

I'm mostly asking due to the lack of documentation/ my inhability to find it.

The class there invokes `this.getColumnWidths()` but it's not defined neither in PopupMenu nor in the ConfigurableMenu class itself, is this some difference between Cinnamon's API and Gnome-Shell's?

Where can I find up to date documentation for it?
