Yes, I have been working away on this while I should probably have been doing something else. Here is what I have, in case anyone wants to either use it themselves, modify it to his or her own ruleset (go ahead), or - better still - offer any suggestions for improvement. I doubt this is the most elegant or efficient bit of coding, it's also a bit of a hack, but it does work (with one small gripe; more later).
First off, I created a frame in the inventory page (charsheet_inventory.xml or whatever your own file is called) and put a title on it. Watch out with the bounds or anchoring; these will necessarily be different for your own character sheet.
<!-- Magic items -->
<genericcontrol name="magicitemsframe">
<bounds>15,390,240,158</bounds>
<frame>
<name>sheetgroup</name>
</frame>
</genericcontrol>
<stringcontrol>
<anchored>
<to>magicitemsframe</to>
<position>insidetop</position>
<offset>0,11</offset>
</anchored>
<center />
<font>sheetlabel</font>
<static>Magic Items</static>
</stringcontrol>
Next, I created a windowlist for any dropped items.
<windowlist name="magicitemlist">
<anchored>
<to>magicitemsframe</to>
<position>over</position>
<offset>-8,-24</offset>
</anchored>
<datasource>.magicitemlist</datasource>
<class>magicitemlistitem</class>
<allowdelete />
<acceptdrop>
<class>item</class>
<field>name</field>
<field>description</field>
</acceptdrop>
<columns>
<filldown />
<width>110</width>
</columns>
<script>
function onSortCompare(w1, w2)
if w1.name.getValue() == "" then
return true;
elseif w2.name.getValue() == "" then
return false;
end
return w1.name.getValue() > w2.name.getValue();
end
</script>
</windowlist>
Then I defined the appropriate classes (first, the clumsily-named "magicitemlistitem"):
<windowclass name="magicitemlistitem">
<sizelimits>
<minimum>
<height>18</height>
</minimum>
</sizelimits>
<sheetdata>
<windowreferencecontrol name="shortcut">
<anchored>
<left>
<anchor>left</anchor>
<offset>0</offset>
</left>
<top>
<anchor>top</anchor>
</top>
<size>
<width>20</width>
<height>20</height>
</size>
</anchored>
<icon>
<normal>button_openwindow</normal>
<empty>button_emptytarget</empty>
<pressed>button_emptytarget</pressed>
</icon>
<class>pcmagicitem</class>
<datasource>.magicitemlistitem</datasource>
</windowreferencecontrol>
<stringfield name="name">
<anchored>
<left>
<anchor>shortcut</anchor>
<offset>0</offset>
</left>
<top>
<anchor>top</anchor>
<offset>5</offset>
</top>
<size>
<width>130</width>
</size>
</anchored>
<font>sheetlabelsmall</font>
</stringfield>
</sheetdata>
</windowclass>
and then the important one, "pcmagicitem". I defined this last one along with the "item" windowclass, in the adventure_items.xml file but I don't think it actually matters (correct me if I'm wrong).
<windowclass name="pcmagicitem">
<datasource>magicitemlistitem</datasource>
<frame>charsheet</frame>

<width>270</width>
<height>370</height>

<height>220</height>
</minimum>
</sizelimits>
<minimize>minimized_item</minimize>

Taken all together, this code allows the following kind of behaviour ...
The party discovers a magic item The DM uses the usual FG2 tools to manage "at-a-glance" and "identified" descriptions Once the item is identified, the DM drags the item to the player's character sheet's magic items box The player now has a list if magic items with links to detailed descriptions (the descriptions from the magic items module or the campaign's items database)
You end up with the kind of thing shown in the attached screenshot here, a dump from the player's screen with all those item screens opened up from the player's character sheet.
This is almost exactly the kind of behaviour I was looking for. The key thing, imo, is that the players have access to the descriptions of the items in their possession, without having to gain access to the books or clumsily cut-and-paste things into notes. As a DM (or GM; I'm old school!), you may have issues with giving the players full descriptions of what their items can do and how they work etc etc but that's up to you.
Right, what was that issue I mentioned? Yes, I guess I must have some class definition messed up somewhere because when the DM drags an item to a character sheet, and that character's player tries to open the item window ... it shows blank. There is an empty item window, with a name but no description. This remains in effect until the player disconnects and then reconnects. I shall see if I can track this down somehow and will then edit this post accordingly.
Ok, so ... comments and suggestions gratefully received.
Thanks.
