The global settings are set both in the "Workplace Shell" object and
on the "XDesktop" notebook page and are stored in the "XWorkplace" app
in OS2.INI. All the global notebook logic is in src\shared\notebook.c.
Note that the large structure called
GLOBALSETTINGS that was used from XFolder 0.1 until XWorkplace 0.9.16 is
gone now. Yes, it almost broke my heart, but I got sick of it. Instead, global settings
are implemented via cmnQuerySetting and cmnSetSetting in
src\shared\common.c now.
By contrast, the individual object settings are stored in
instance data, which is declared in the .IDL files. Most of these are
stored and retrieved using the normal WPS mechanism
(wpSaveDeferred/wpRestoreData) and can have
a certain "transparent"
value, which means that the global setting is to be used instead.
