DESCRIPTION
The QDataView class provides read-only SQL forms.
This class provides a form which displays SQL field data from a record
buffer. Because QDataView does not support editing it uses less
resources than a QDataBrowser. This class is well suited for displaying
read-only data from a SQL database.
If you want a to present your data in an editable form use
QDataBrowser; if you want a table-based presentation of your data use
QDataTable.
The form is associated with the data view with setForm() and the record
is associated with setRecord(). You can also pass a QSqlRecord to the
refresh() function which will set the record to the given record and
read the record's fields into the form.
See also Database Classes.
MEMBER FUNCTION DOCUMENTATIONQDataView::QDataView ( QWidget * parent = 0, const char * name = 0, WFlags fl
= 0 )
Constructs a data view which is a child of parent, called name, and
with widget flags fl.
QDataView::~QDataView ()
Destroys the object and frees any allocated resources.
void QDataView::clearValues () [virtual slot]
Clears the default form's values. If there is no default form, nothing
happens. All the values are set to their 'zero state', e.g. 0 for
numeric fields, "" for string fields.
QSqlForm * QDataView::form ()
Returns the default form used by the data view, or 0 if there is none.
See also setForm().
void QDataView::readFields () [virtual slot]
Causes the default form to read its fields from the record buffer. If
there is no default form, or no record, nothing happens.
See also setForm().
QSqlRecord * QDataView::record ()
Returns the default record used by the data view, or 0 if there is
none.
See also setRecord().
void QDataView::refresh ( QSqlRecord * buf ) [virtual slot]
Causes the default form to display the contents of buf. If there is no
default form, nothing happens.The buf also becomes the default record
for all subsequent calls to readFields() and writefields(). This slot
is equivalant to calling:
myView.setRecord( record );
myView.readFields();
See also setRecord() and readFields().
void QDataView::setForm ( QSqlForm * form ) [virtual]
Sets the form used by the data view to form. If a record has already
been assigned to the data view, the form will display that record's
data.
See also form().
void QDataView::setRecord ( QSqlRecord * record ) [virtual]
Sets the record used by the data view to record. If a form has already
been assigned to the data view, the form will display the data from
record in that form.
See also record().
void QDataView::writeFields () [virtual slot]
Causes the default form to write its fields to the record buffer. If
there is no default form, or no record, nothing happens.
See also setForm().
