29 The QDataView class provides read-only SQL forms.
30 This class provides a form which displays SQL field data from a record
32 buffer. Because QDataView does not support editing it uses less
33 resources than a QDataBrowser. This class is well suited for displaying
34 read-only data from a SQL database.
35 If you want a to present your data in an editable form use
37 QDataBrowser; if you want a table-based presentation of your data use
38 QDataTable.
39 The form is associated with the data view with setForm() and the record
41 is associated with setRecord(). You can also pass a QSqlRecord to the
42 refresh() function which will set the record to the given record and
43 read the record's fields into the form.
44 See also Database Classes.
46
49 = 0 )
50 Constructs a data view which is a child of parent, called name, and
51 with widget flags fl.
52
54 Destroys the object and frees any allocated resources.
55
57 Clears the default form's values. If there is no default form, nothing
58 happens. All the values are set to their 'zero state', e.g. 0 for
59 numeric fields, "" for string fields.
60
62 Returns the default form used by the data view, or 0 if there is none.
63 See also setForm().
65
67 Causes the default form to read its fields from the record buffer. If
68 there is no default form, or no record, nothing happens.
69 See also setForm().
71
73 Returns the default record used by the data view, or 0 if there is
74 none.
75 See also setRecord().
77
79 Causes the default form to display the contents of buf. If there is no
80 default form, nothing happens.The buf also becomes the default record
81 for all subsequent calls to readFields() and writefields(). This slot
82 is equivalant to calling:
83 myView.setRecord( record );
85 myView.readFields();
86 See also setRecord() and readFields().
88
90 Sets the form used by the data view to form. If a record has already
91 been assigned to the data view, the form will display that record's
92 data.
93 See also form().
95
97 Sets the record used by the data view to record. If a form has already
98 been assigned to the data view, the form will display the data from
99 record in that form.
100 See also record().
102
104 Causes the default form to write its fields to the record buffer. If
105 there is no default form, or no record, nothing happens.
106 See also setForm().
