PM Windows style

[Chompy]

Is it possible to change the style of it? If so, what's the object for it?

Also, what are the other objects for the taskbar and the menu?
I know of Serverlist_TaskBar, but what's the others?

Edit:

Well, what I really need:

The Playerlist itself (If it allows style setting)

Taskbar Button (-> button)
Taskbar Menu
PMs window


Anyone know them and can post them?

Edit2:
Is there a way to see if a player changes their guistyle? Because if you change the taskbar for example with a script, the player can change it back..

And, is there a $pref for the current player's style? There is one for their default skin (Which hasn't been added to the wiki..! (Client and Clientside Functions))
