I'm no expert in skinning but :
$paned configure \http://www.tcl.tk/man/tcl8.4/TkCmd/panedwindow.htm#M13
-showhandle [::skin::getKey chat_sash_showhandle] \
-sashpad [::skin::getKey chat_sash_pady] \
-sashwidth [::skin::getKey chat_sash_width] \
-sashrelief [::skin::getKey chat_sash_relief]
(in other words, do the chat_sash_showhandle set to 0, then add a chat_sash_relief and set it to 'flat', then add a chat_sash_width and set it to 0)
2) humm.. don't know, I'm guessing it can't be done, probably because there is no key for the 'foreground' color of the entries... sorry... try putting the bg to grey or something, look what this guy did here : http://www.amsn-project.net/forums/viewtopic.php?t=3580
OR, you could change what needs to be changed and submit us patches for fixing that.
3) the wiki *should* have the complete list, but it *can* be outdated..
The best way to get a FULL LIST, is to search in the code... it's either in gui.tcl (usually) or in skins.tcl, every key is being set to a default value in the code, so that if it's not in the settings.xml file, amsn won't break, so it's as simple as doing :
grep "skin::setKey" *.tcl
In amsn's directory, or search for "skin::setKey" in gui.tcl and skins.tcl.
to figure out what it does, if the name is unclear, just grep that name and see where it's used.. shouldn't be that hard...
4) define "a specific element" ? the width/height is usually calculated using some algorithm in order to pack all widgets in a window, what you can modify is the padx/pady of the elements. The only other thing that the skinner has control over in terms of width/height is the width/height of the "Display pictures in contact list" feature, since those DP are resized to have the same size as the buddy icon of the contact list.
The background picture has nothing to do with size, you put the size you want, it will depend if the user has a small window, which resolution, if he maximized the contact list or not, etc... for sure, if you use 300x800 but you resize amsn to fit on 100x200, you can't see the whole image!
5) The padding is in pixels, yes
6) yes, X is horizontal, and no, it is applied on the left and right edges. It depends though on what you need it for, if it's for the contact list for example or something, there might be a setting to specific the X position in which to start drawing the contacts... also, if there is an image on that widget, you can put a padding on the left of the image using transparent
background in order to add padding only on the left.. otherwise, I don't think so, but tell us what you need *exactly* and we might be able to help, everything is a special case.
7) yeah, it happens, you can change it back, we still need to add an advanced option for that.. in the meantime, if you searched you would have found the answer quite fast :http://www.amsn-project.net/forums/viewtopic.php?t=1824&highlight=closingdocks
8 ) your english is great, didn't notice english isn't your primary language.
