All callback from a widget into a module (e.g. for retrieving the status
or the criticality state) now get a widget passed. This has the purpose
of allowing a module to store state/widget specific data somewhere. This
way, for instance, it is possible to store the interface name as part of
the widget, thus making it possible to show the status of the correct
interface.
Pass the "output" object to the modules' constructor to allow them to
define their own callbacks.
Any user-provided callbacks take precedence and override those of the
module.
The i3 output now has a separate thread that continuously monitors stdin
for incoming click events. The generic output class also has methods for
registering callbacks (as commands). For now, by default, scroll events
will be used to emulate the next/previous workspace.
Add a new module "disk" that takes an optional parameter (the path) and
displays free & total disk space, along with the usage percentage.
Also, added Tunnel/VPN support to the themeing of the "net" module.
First, cache lookups were bugged... Second, the output needs to call
data() first, everything else later.
This is a bit nasty, and I'll consider re-visiting this, but right now,
I don't see any other way, given that modules can now be iterated.
Add a module that displays the status of all NICs (interface name, list
of IPs and state).
In its status, it also exposes whether it's a WiFi or a wired NIC.
For this functionality, additional code was implemented to allow a
module to add multiple elements to the bar at once. The framework calls
the module until its "next()" method return False.
