SFX is the "old" framework, used for historical reasons.

+Changing the system: <b>In Order to add a function to a shell,
+Add an entry to the .sdi file corresponding to that SfxShell</b><BR>

+<PRE><FONT style="background-color: black" color="white">SID_PASTE [ ExecMethod = ExecDrawFunc;
StateMethod = GetDrawFuncState; Export = FALSE; ]</FONT></PRE><BR>
+The "state" method is the method called to checked whether that command is active now. The "exec"
method is called when the command should be processed by the shell. Both functions obtain a
SfxRequest Object as a parameter, declared in ./include/sfx2/request.hxx.<BR>
+Each Application Window has ONE Dispatcher.
+This registers all SfxShells (or rather their
+subclasses) which can get commands from the user AT THE MOMENT.
+These shells are created when the edit mode they
+are part of is first used, but not discarded until the window closes.
+./sfx2/source/control/dispatch.cxx:
+void SfxDispatcher::Pop receives Pushes and Pops
+of the shell to/from the stack.
+The real Pushing/Popping, however, is done during
+SfxDispatcher::FlushImpl
+Main dispatching routine In
+./sfx2/source/control/unoctitm.cxx
+SfxDispatchController_Impl::dispatch.
+<BR>
+SfxDispatchController::_FindServer
+gets the SfxInterfaces of the shells. They are defined by macro calls
+to SFX_IMPL_INTERFACE, defined in include/sfx2/shell.hxx .
+
+Upon GetInterface, they yield their pInterface,
+which, upon GetSlot, returns a SfxSlot of that Shell
+For that command, which is then Executed with
+Dispatcher::Execute.
+If the program is set into another mode, for
+example by clicking a hovering object in writer
+after Text editing, all shells are removed from
+the dispatcher and new shells are pushed
+to match the current mode.
+<BR>
+<B> How to build menus</B><BR>
+In order to introduce a menu command, the uno command must be linked to a slot name.<BR>
+This is done in different sdi files, such as sfx2/sdi/sfx.sdi.
+There, you <U>define</U> the slot:<BR>
+<FONT style="color: red">Structure:</FONT>

+<FONT style="background-color: black" color="white">
+SfxVoidItem uno_name_the_part_after_colon SID_COMMAND_NAME
+()
+[
+ /* initialization of variables is coming here */
+]
+</PRE>
+</FONT>
+In ./include/sfx2/sfxsids.hrc, the defines of the slot names and their numbers are entered. The
numbers are just needed because definitions cannot be enums, and for compatibility.<BR>
+
+In ./officecfg/registry/data/org/openoffice/Office/UI,
+there are .xcu ended xml files that define the single menu items.
+They contain the US- language name and the .uno: command.<BR>
+In ./include/sfx2/sfxcommands.h, the uno command names are listed.
+
+
+<BR><BR>
+The resource compiler, which creates files some GetState methods refer to, is in the ./rsc
directory. It is a separate executable, invoked at compile time.<BR>
