53 /* Converting Lisp menu tree descriptions to lwlib's `widget_value' form.
55 menu_item_descriptor_to_widget_value() converts a lisp description of a
56 menubar into a tree of widget_value structures. It allocates widget_values
57 with malloc_widget_value() and allocates other storage only for the `key'
58 slot. All other slots are filled with pointers to Lisp_String data. We
59 allocate a widget_value description of the menu or menubar, and hand it to
60 lwlib, which then makes a copy of it, which it manages internally. We then
61 immediately free our widget_value tree; it will not be referenced again.
63 Incremental menu construction callbacks operate just a bit differently.
64 They allocate widget_values and call replace_widget_value_tree() to tell
65 lwlib to destructively modify the incremental stub (subtree) of its
66 separate widget_value tree.
68 This function is highly recursive (it follows the menu trees) and may call
69 eval. The reason we keep pointers to lisp string data instead of copying
70 it and freeing it later is to avoid the speed penalty that would entail
71 (since this needs to be fast, in the simple cases at least). (The reason
72 we malloc/free the keys slot is because there's not a lisp string around
73 for us to use in that case.)
75 Since we keep pointers to lisp strings, and we call eval, we could lose if
76 GC relocates (or frees) those strings. It's not easy to gc protect the
77 strings because of the recursive nature of this function, and the fact that
78 it returns a data structure that gets freed later. So... we do the
79 sleaziest thing possible and inhibit GC for the duration. This is probably
82 We do not have to worry about the pointers to Lisp_String data after
83 this function successfully finishes. lwlib copies all such data with
87 menu_item_descriptor_to_widget_value_1 (Lisp_Object desc,

819 /* Setting zmacs-region-stays is necessary here because executing a command
820 from a menu is really a two-command process: the first command (bound to
821 the button-click) simply pops up the menu, and returns. This causes a
822 sequence of magic-events (destined for the popup-menu widget) to begin.
823 Eventually, a menu item is selected, and a menu-event blip is pushed onto
824 the end of the input stream, which is then executed by the event loop.
826 So there are two command-events, with a bunch of magic-events between
827 them. We don't want the *first* command event to alter the state of the
828 region, so that the region can be available as an argument for the second
