DESCRIPTION

29       The QDataView class provides read-only SQL forms.
30
31       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
36       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
40       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
45       See also Database Classes.

MEMBER FUNCTION DOCUMENTATION

QDataView::QDataView ( QWidget * parent = 0, const char * name = 0, WFlags fl

49       = 0 )
50       Constructs a data view which is a child of parent, called name, and
51       with widget flags fl.
52

QDataView::~QDataView ()

54       Destroys the object and frees any allocated resources.
55

void QDataView::clearValues () [virtual slot]

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

QSqlForm * QDataView::form ()

62       Returns the default form used by the data view, or 0 if there is none.
63
64       See also setForm().
65

void QDataView::readFields () [virtual slot]

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
70       See also setForm().
71

QSqlRecord * QDataView::record ()

73       Returns the default record used by the data view, or 0 if there is
74       none.
75
76       See also setRecord().
77

void QDataView::refresh ( QSqlRecord * buf ) [virtual slot]

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
84           myView.setRecord( record );
85           myView.readFields();
86
87       See also setRecord() and readFields().
88

void QDataView::setForm ( QSqlForm * form ) [virtual]

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
94       See also form().
95

void QDataView::setRecord ( QSqlRecord * record ) [virtual]

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
101       See also record().
102

void QDataView::writeFields () [virtual slot]

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
107       See also setForm().
