-<hr><a name="details"></a><h2>Detailed Description</h2>
-
-
-The TQDataBrowser class provides data manipulation and
-navigation for data entry forms.
-<p>
-
-
-<p> A high-level API is provided for navigating through data records
-in a cursor, for inserting, updating and deleting records, and for
-refreshing data in the display.
-<p> If you want a read-only form to present database data use
-<a href="qdataview.html">TQDataView</a>; if you want a table-based presentation of your data use
-<a href="qdatatable.html">TQDataTable</a>.
-<p> A TQDataBrowser is used to associate a dataset with a form in much
-the same way as a TQDataTable associates a dataset with a table.
-Once the data browser has been constructed it can be associated
-with a dataset with <a href="#setSqlCursor">setSqlCursor</a>(), and with a form with
-<a href="#setForm">setForm</a>(). Boundary checking, sorting and filtering can be set
-with <a href="#setBoundaryChecking">setBoundaryChecking</a>(), <a href="#setSort">setSort</a>() and <a href="#setFilter">setFilter</a>(),
-respectively.
-<p> The <a href="#insertCurrent">insertCurrent</a>() function reads the fields from the default
-form into the default cursor and performs the insert. The
-<a href="#updateCurrent">updateCurrent</a>() and <a href="#deleteCurrent">deleteCurrent</a>() functions perform similarly to
-update and delete the current record respectively.
-<p> The user can be asked to confirm all edits with <a href="#setConfirmEdits">setConfirmEdits</a>().
-For more precise control use <a href="#setConfirmInsert">setConfirmInsert</a>(),
-<a href="#setConfirmUpdate">setConfirmUpdate</a>(), <a href="#setConfirmDelete">setConfirmDelete</a>() and <a href="#setConfirmCancels">setConfirmCancels</a>().
-Use <a href="#setAutoEdit">setAutoEdit</a>() to control the behaviour of the form when the
-user edits a record and then navigates.
-<p> The record set is navigated using <a href="#first">first</a>(), <a href="#next">next</a>(), <a href="#prev">prev</a>(), <a href="#last">last</a>()
-and <a href="#seek">seek</a>(). The form's display is updated with <a href="#refresh">refresh</a>(). When
-navigation takes place the <a href="#firstRecordAvailable">firstRecordAvailable</a>(),
-<a href="#lastRecordAvailable">lastRecordAvailable</a>(), <a href="#nextRecordAvailable">nextRecordAvailable</a>() and
-<a href="#prevRecordAvailable">prevRecordAvailable</a>() signals are emitted. When the cursor record
-is changed due to navigation the <a href="#cursorChanged">cursorChanged</a>() signal is
-emitted.
-<p> If you want finer control of the insert, update and delete
-processes then you can use the lower level functions to perform
-these operations as described below.
-<p> The form is populated with data from the database with
-<a href="#readFields">readFields</a>(). If the user is allowed to edit, (see <a href="#setReadOnly">setReadOnly</a>()),
-write the form's data back to the cursor's edit buffer with
-<a href="#writeFields">writeFields</a>(). You can clear the values in the form with
-<a href="#clearValues">clearValues</a>(). Editing is performed as follows:
-<ul>
-<li> <em>insert</em> When the data browser enters insertion mode it emits the
-<a href="#primeInsert">primeInsert</a>() signal which you can connect to, for example to
-pre-populate fields. Call writeFields() to write the user's edits to
-the cursor's edit buffer then call <a href="#insert">insert</a>() to insert the record
-into the database. The <a href="#beforeInsert">beforeInsert</a>() signal is emitted just before
-the cursor's edit buffer is inserted into the database; connect to
-this for example, to populate fields such as an auto-generated
-primary key.
-<li> <em>update</em> For updates the <a href="#primeUpdate">primeUpdate</a>() signal is emitted when
-the data browser enters update mode. After calling writeFields()
-call <a href="#update">update</a>() to update the record and connect to the <a href="#beforeUpdate">beforeUpdate</a>()
-signal to manipulate the user's data before the update takes place.
-<li> <em>delete</em> For deletion the <a href="#primeDelete">primeDelete</a>() signal is emitted when
-the data browser enters deletion mode. After calling <a href="#writeFields">writeFields</a>()
-call <a href="#del">del</a>() to delete the record and connect to the <a href="#beforeDelete">beforeDelete</a>()
-signal, for example to record an audit of the deleted record.
-</ul>

-<hr><h2>Member Type Documentation</h2>
-<h3 class=fn><a name="Boundary-enum"></a>TQDataBrowser::Boundary</h3>
-
-<p> This enum describes where the data browser is positioned.
-<ul>
-<li><tt>TQDataBrowser::Unknown</tt> - the boundary cannot be determined (usually because
-there is no default cursor, or the default cursor is not active).
-<li><tt>TQDataBrowser::None</tt> - the browser is not positioned on a boundary, but it is
-positioned on a record somewhere in the middle.
-<li><tt>TQDataBrowser::BeforeBeginning</tt> - the browser is positioned before the
-first available record.
-<li><tt>TQDataBrowser::Beginning</tt> - the browser is positioned at the first record.
-<li><tt>TQDataBrowser::End</tt> - the browser is positioned at the last
-record.
-<li><tt>TQDataBrowser::AfterEnd</tt> - the browser is positioned after the last
-available record.
-</ul>

-</h3>
-
-<p> This signal is emitted just before the cursor's edit buffer is
-deleted from the database. The <em>buf</em> parameter points to the edit
-buffer being deleted. You might connect to this signal to capture
-some auditing information about the deletion.
-
-<h3 class=fn>void <a name="beforeInsert"></a>TQDataBrowser::beforeInsert ( <a href="qsqlrecord.html">TQSqlRecord</a>&nbsp;*&nbsp;buf )<tt> [signal]</tt>

-
-<h3 class=fn>void <a name="del"></a>TQDataBrowser::del ()<tt> [virtual slot]</tt>
-</h3>
-Performs a delete operation on the data browser's cursor. If there
-is no default cursor or no default form, nothing happens.
-<p> Otherwise, the following happens:
-<p> The current form's record is deleted from the database, providing
-that the data browser is not in insert mode. If the data browser
-is actively inserting a record (see <a href="#insert">insert</a>()), the insert action
-is canceled, and the browser navigates to the last valid record

-</h3>
-Performs a delete on the default cursor using the values from the
-default form and updates the default form. If there is no default
-form or no default cursor, nothing happens. If the deletion was
-successful, the cursor is repositioned to the nearest record and
-TRUE is returned. The nearest record is the next record if there
-is one otherwise the previous record if there is one. If an error
-occurred during the deletion from the database, <a href="#handleError">handleError</a>() is
-called and FALSE is returned.
-<p> <p>See also <a href="qwidget.html#cursor-prop">cursor</a>, <a href="#form">form</a>(), and <a href="#handleError">handleError</a>().

-or no default cursor, nothing happens. If the data browser
-successfully navigated to the first record, the default cursor is
-primed for update and the <a href="#primeUpdate">primeUpdate</a>() signal is emitted.
-<p> If the browser is already positioned on the first record nothing
-happens.
-<p>
-<h3 class=fn>void <a name="firstRecordAvailable"></a>TQDataBrowser::firstRecordAvailable ( bool&nbsp;available )<tt> [signal]</tt>
-</h3>
-
-<p> This signal is emitted whenever the position of the cursor

-implementation warns the user with a message box.
-
-<h3 class=fn>void <a name="insert"></a>TQDataBrowser::insert ()<tt> [virtual slot]</tt>
-</h3>
-Performs an insert operation on the data browser's cursor. If
-there is no default cursor or no default form, nothing happens.
-<p> If auto-editing is on (see <a href="#setAutoEdit">setAutoEdit</a>()), the following happens:
-<p> <ul>
-<li> If the browser is already actively inserting a record,
-the current form's data is inserted into the database.
-<li> If the browser is not inserting a record, but the current record
-was changed by the user, the record is updated in the database with
-the current form's data (i.e. with the changes).
