A few plasma questions

[Jeremy Webster]

Hello all, I'm new, and I have no idea if this is the right place for 
this.  let me know if it isn't.


I've been trying to teach myself how to write plasma applets, and I have 
a slideshow applet (screenshot 
<http://home.olemiss.edu/%7Ejwebster/projects/slideshow/screenshot.jpg>) 
that basically displays all the pictures within a directory.  Simple, I 
know, but I gotta start somewhere. 

It works pretty well, but I have a few things I'd like to add before I 
send it out into the world.

I'd like to add a settings widget so that people can change the size, 
the directory, whether or not the filename is visible, etc..  But I 
can't figure out how plasma applets deal with this.  For instance, how 
do I get the little wrench to show up when there's a mouse-over?  How in 
general are settings handled? 

How do I set the icon for my plasma-app so that it shows up in the Add 
Widgets widget?  My applet shows up, but it has the default icon that 
several other applets have.

Where can I find the plasma API?  Has this been released to the public?  
I can't find it anywhere.

Is the source code for the Analog Clock applet available?  I think that 
would help me a lot, but I don't know where to find it.


Answers or pointers to where I can find answers are greatly appreciated.

Thanks for your time
