<hr><a name="details"></a><h2>Detailed Description</h2>
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="ntqdatabrowser.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="ntqdatatable.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="ntqsqlrecord.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>.
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="TQDataView"></a>TQDataView::TQDataView ( <a href="ntqwidget.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="ntqsqlform.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="ntqsqlrecord.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="ntqsqlrecord.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="ntqsqlform.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="ntqsqlrecord.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>().
