66 /* Converting Lisp menu tree descriptions to lwlib's `widget_value' form.
|
|
|
67
|
|
|
68 menu_item_descriptor_to_widget_value() converts a lisp description of a
|
|
|
69 menubar into a tree of widget_value structures. It allocates widget_values
|
|
|
70 with malloc_widget_value() and allocates other storage only for the `key'
|
|
|
71 slot. All other slots are filled with pointers to Lisp_String data. We
|
|
|
72 allocate a widget_value description of the menu or menubar, and hand it to
|
|
|
73 lwlib, which then makes a copy of it, which it manages internally. We then
|
|
|
74 immediately free our widget_value tree; it will not be referenced again.
|
|
|
75
|
|
|
76 Incremental menu construction callbacks operate just a bit differently.
|
|
|
77 They allocate widget_values and call replace_widget_value_tree() to tell
|
|
|
78 lwlib to destructively modify the incremental stub (subtree) of its
|
|
|
79 separate widget_value tree.
|
|
|
80
|
|
|
81 This function is highly recursive (it follows the menu trees) and may call
|
|
|
82 eval. The reason we keep pointers to lisp string data instead of copying
|
|
|
83 it and freeing it later is to avoid the speed penalty that would entail
|
|
|
84 (since this needs to be fast, in the simple cases at least). (The reason
|
|
|
85 we malloc/free the keys slot is because there's not a lisp string around
|
|
|
86 for us to use in that case.)
|
|
|
87
|
|
|
88 Since we keep pointers to lisp strings, and we call eval, we could lose if
|
|
|
89 GC relocates (or frees) those strings. It's not easy to gc protect the
|
|
|
90 strings because of the recursive nature of this function, and the fact that
|
|
|
91 it returns a data structure that gets freed later. So... we do the
|
|
|
92 sleaziest thing possible and inhibit GC for the duration. This is probably
|
|
|
93 not a big deal...
|
|
|
94
|
|
|
95 We do not have to worry about the pointers to Lisp_String data after
|
|
|
96 this function successfully finishes. lwlib copies all such data with
|
|
|
97 strdup(). */
