174
175 SYNOPSIS
176 [IS.], struct Hook *
177
178 LOCATION
179 List.mui
180
181 FUNCTION
182 The provided hook indicates the sort ordering of two list entries.
183 The hook receives list-entry data pointers as its second and third
184 arguments. The hook should return a negative value if the first entry
185 should be placed before the second entry, a positive value if the
186 first entry should be placed after the second entry, and zero if the
187 entries are equal.
188
189 In addition to being used internally for sorting operations, this hook
190 will be called when MUIM_List_Compare is externally invoked.
191
192 If this attribute is not specified or is set to NULL, all list entries
193 must be strings.

212
213 SYNOPSIS
214 [IS.], struct Hook *
215
216 LOCATION
217 List.mui
218
219 FUNCTION
220 The provided hook indicates whether a particular list entry
221 may be multiselected. The hook receives the list-entry data pointer as
222 its third argument, and returns a Boolean value. If this attribute is
223 not specified or is set to NULL, all list entries are considered
224 multi-selectable.
225
226 Whenever an entry is about to be selected, this hook is called if
227 there are other entries already selected. If the hook returns TRUE,
228 the entry may be multi-selected; if the hook returns FALSE, the entry
229 remains unselected.
230
231 Additionally, if a non-multi-selectable entry has been selected (as
232 the only selected entry in the list), any attempt to select an
233 additional entry will fail.
