The TQDataView class provides read-only SQL forms.
< p >
< p > This class provides a form which displays SQL field data from a
record buffer. Because TQDataView does not support editing it uses
less resources than a < a href = "tqdatabrowser.html" > TQDataBrowser< / a > . This class is well suited for
displaying read-only data from a SQL database.
< p > If you want a to present your data in an editable form use
TQDataBrowser; if you want a table-based presentation of your data
use < a href = "tqdatatable.html" > TQDataTable< / a > .
< p > The form is associated with the data view with < a href = "#setForm" > setForm< / a > () and the
record is associated with < a href = "#setRecord" > setRecord< / a > (). You can also pass a
< a href = "tqsqlrecord.html" > TQSqlRecord< / a > to the < a href = "#refresh" > refresh< / a > () function which will set the record to
the given record and read the record's fields into the form.
< p > See also < a href = "database.html" > Database Classes< / a > .

< h3 class = fn > < a name = "TQDataView" > < / a > TQDataView::TQDataView ( < a href = "tqwidget.html" > TQWidget< / a > * parent = 0, const char * name = 0, WFlags fl = 0 )
< / h3 >
Constructs a data view which is a child of < em > parent< / em > , called < em > name< / em > , and with widget flags < em > fl< / em > .
< h3 class = fn > < a name = "~TQDataView" > < / a > TQDataView::~TQDataView ()
< / h3 >
Destroys the object and frees any allocated resources.
< h3 class = fn > void < a name = "clearValues" > < / a > TQDataView::clearValues ()< tt > [virtual slot]< / tt >
< / h3 >
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.
< h3 class = fn > < a href = "tqsqlform.html" > TQSqlForm< / a > * < a name = "form" > < / a > TQDataView::form ()
< / h3 >
Returns the default form used by the data view, or 0 if there is
none.
< p > < p > See also < a href = "#setForm" > setForm< / a > ().
< h3 class = fn > void < a name = "readFields" > < / a > TQDataView::readFields ()< tt > [virtual slot]< / tt >
< / h3 >
Causes the default form to read its fields from the record buffer.
If there is no default form, or no record, nothing happens.
< p > < p > See also < a href = "#setForm" > setForm< / a > ().
< h3 class = fn > < a href = "tqsqlrecord.html" > TQSqlRecord< / a > * < a name = "record" > < / a > TQDataView::record ()
< / h3 >
Returns the default record used by the data view, or 0 if there is
none.
< p > < p > See also < a href = "#setRecord" > setRecord< / a > ().
< h3 class = fn > void < a name = "refresh" > < / a > TQDataView::refresh ( < a href = "tqsqlrecord.html" > TQSqlRecord< / a > * buf )< tt > [virtual slot]< / tt >
< / h3 >
Causes the default form to display the contents of < em > buf< / em > . If
there is no default form, nothing happens.The < em > buf< / em > also becomes
the default record for all subsequent calls to < a href = "#readFields" > readFields< / a > () and
writefields(). This slot is equivalant to calling:
< p > < pre >
myView.setRecord( record );
myView.readFields();
< / pre >
< p > < p > See also < a href = "#setRecord" > setRecord< / a > () and < a href = "#readFields" > readFields< / a > ().
< h3 class = fn > void < a name = "setForm" > < / a > TQDataView::setForm ( < a href = "tqsqlform.html" > TQSqlForm< / a > * form )< tt > [virtual]< / tt >
< / h3 >
Sets the form used by the data view to < em > form< / em > . If a record has
already been assigned to the data view, the form will display that
record's data.
< p > < p > See also < a href = "#form" > form< / a > ().
< h3 class = fn > void < a name = "setRecord" > < / a > TQDataView::setRecord ( < a href = "tqsqlrecord.html" > TQSqlRecord< / a > * record )< tt > [virtual]< / tt >
< / h3 >
Sets the record used by the data view to < em > record< / em > . If a form has
already been assigned to the data view, the form will display the
data from < em > record< / em > in that form.
< p > < p > See also < a href = "#record" > record< / a > ().
< h3 class = fn > void < a name = "writeFields" > < / a > TQDataView::writeFields ()< tt > [virtual slot]< / tt >
< / h3 >
Causes the default form to write its fields to the record buffer.
If there is no default form, or no record, nothing happens.
< p > < p > See also < a href = "#setForm" > setForm< / a > ().
