Tomas,
I'm not sure I understand your question. Are you familiar with the
following XP code?
abi/src/wp/ap/xp/ap_Toolbar_ActionSet.cpp
abi/src/wp/ap/xp/ap_Toolbar_Functions.cpp
The first file lays out a table which indicates which types of changes to
the document (AV_CHG_*) affect the state of a given toolbar item.
Those changes in turn trigger logic in the second file, which set the
toolbar item state accordingly. For example, setting EV_TIS_Gray tells
platform code to disable the item via the EV_TIS_ShouldBeGray() macro:
abi/src/af/ev/xp/ev_Toolbar_Actions.h
abi/src/af/ev/<platform>/ev_<os>Toolbar.cpp
Does that answer your question?
Paul
