21 An accepting-values stream diverts the calls to accept into calling
22 accept-present-default, as described in the spec. The output record
23 produced by accept-present-default, as well as the current value of
24 that query, arguments that were passed to accept, etc. are stored in a
25 query object. The stream stores all the query objects for this
26 invocation of accepting-values. The record created and returned by
27 accept-present-default must be a subclass of updating-output-record.
28
29 After the initial output records are drawn, invoke-accepting-values
30 blocks accepting commands. The state of the dialog state machine is changed
31 via these commands. The commands currently are:
32
33 COM-SELECT-QUERY query-id -- calls the method select-query with the
34 corresponding query object and output record object. When select-query returns
35 the "next" field, if any, is selected so the user can move from field to field
36 easily.
37
38 COM-CHANGE-QUERY query-id value -- This command is used to directly change the
39 value of a query field that does not need to be selected first for input. For
40 example, a user would click directly on a radio button without selecting the
41 gadget first.
42
43 COM-DESELECT-QUERY -- deselects the currently selected query.
44
45 COM-QUERY-EXIT -- Exits accepting-values
46
47 COM-QUERY-ABORT -- Aborts accepting-values
48
49 These commands are generated in two ways. For query fields that are entirely
50 based on CLIM drawing commands and presentations, these are emitted by
51 presentation translators. There is a presentation type selectable-query that
52 throws com-select-query for the :select gesture. Fields that are based on
53 gadgets have to throw presentations from their callbacks. This can be done
54 using the method on p. 305 of the Franz CLIM user guide, or by using the
55 McCLIM function throw-object-ptype.
56
57 After a command is executed the body of accepting-values is rerun, calling
58 accept-present-default again to update the fields' graphic appearance. [This
59 may be calling these methods too often an may change in the future]. The
60 values returned by the user's calls to accept are come from the query objects.
61
62
63 If a query field is selectable than it should implement the method
64 select-query:
65
66 SELECT-QUERY stream query record -- Make a query field active and do any
67 input. This should change the query object and setf (changedp query). This
68 method might be interrupted at any time if the user selects another field.
