Joaquin--
Thanks a lot for the dynamic menu stuff. I'm still a little hazy on some
of the implementation details...
First off, the XAP_Menu_Id that is needed to tie all the menus
together... how do I get one of these? Someone suggested using
AP_MENU_ID__BOGUS2__ + N (where N > 1) but I see that this is
probably not a good long term solution.
I have gone ahead and created new objects for the label, layout
item, and action classes. I'm not sure if what I've done is right, and
still have a few questions:
EV_Menu_Label* ThesaurusLabel = new EV_Menu_Label(
ThesaurusID,
"/&Tools/Thesaurus",
"Open the thesaurus and search for synonyms"
);
EV_Menu_LayoutItem* ThesaurusLayoutItem = new EV_Menu_LayoutItem(
ThesaurusID,
EV_MLF_Normal
);
EV_Menu_Action* ThesaurusAction = new EV_Menu_Action(
ThesaurusID,
0, // no, it doesn't have a sub menu
1, // yes, it raises a dialog
0, // no, it's not a checkbox item
"???", // what goes here?
NULL,
NULL
);
But once I create these objects, I'm not quite sure how to add them
to the menu. In other words, how do I get a pointer to the
EV_Menu_Layout*, EV_Menu_ActionSet*, and EV_Menu_LabelSet*
that I need in order to call the addLayout(), adAction(), and addLabel()
functions, respectively?
The XAP_App::getApp() function seems like the right place to start,
but the further I go into the code it seems like the menus are private
or protected members of the implementation classes and I don't see
how to get to them.
The only other question I have at present is how do I determine
when the menu item has been clicked by the user? Can I set up a
callback function of some sort?
Thanks a lot for your help,
Jared
