text_item-value

text_item <- value_set: [chain|function]*

Set of possible values. This slot is used by the default completion mechanism built in class text_item. See text_item->complete and text_item<-completions. The interpretation of this slot is:

@nil text_item<-completions fails (no completion).
@default text_item<-completions activates type<-value_set on the associated text_item<-type.
chain object text_item<-completions answers with this chain.
function object text_item<-completions invokes the function and returns the result. During execution of the function @arg1 is bound to the file return of text_item<-split_completions. If this function is invoked to generate all values for opening a combo-box, @arg1 is bound to the empty name (” ). The function is supposed to return a chain of possible values whose textual description starts with @arg1. Note that text_item->complete will not consider elements of the chain whose object<-print_name does not start with text_item<-displayed_value. Using @arg1 to select candidates is only useful if this speeds up the selection process.
