[E-devel] events

[Brian M. <bma...@ma...>]

As you can see with the deskswitcher epplet, if you switch desktops by
other means (alt-f?), it does not get update. There would be two ways to
fix this. One would be to implement timers (which i'm working on anyway)
and have them poll to see if the desktop has been switched. The other
would be to have e broadcast and event when a desktop is switched, and
allow epplets to accept the events.
The second would be more code, but would probably mean less CPU. If you
had 20+ epplets each polling every .05 - .25 secs for various information,
how cpu intensive would this be?
I can see alot of uses for something like this. For instance, every
window iconify could broadcast an event allowing a taskbar / iconbar
epplet to catch the iconified window or change the state of its
graphics. 

We would need to define event types (E_EVENT_DESKTOP_SWITCH,
E_EVENT_BORDER_ICONIFY, etc) and set up a broadcast and receive
mechanism. Could we adapt ecore's event/callback system to this?

Let me know what you think
