The TQSqlDriverPlugin class provides an abstract base for custom <a href="qsqldriver.html">TQSqlDriver</a> plugins.
<p> 

<p> The SQL driver plugin is a simple plugin interface that makes it
easy to create your own SQL driver plugins that can be loaded
dynamically by TQt.
<p> Writing a SQL plugin is achieved by subclassing this base class,
reimplementing the pure virtual functions <a href="#keys">keys</a>() and <a href="#create">create</a>(), and
exporting the class with the <tt>Q_EXPORT_PLUGIN</tt> macro. See the SQL
plugins that come with TQt for example implementations (in the
<tt>plugins/src/sqldrivers</tt> subdirectory of the source
distribution). Read the <a href="plugins-howto.html">plugins
    documentation</a> for more information on plugins.
<p>See also <a href="plugins.html">Plugins</a>.

<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="TQSqlDriverPlugin"></a>TQSqlDriverPlugin::TQSqlDriverPlugin ()
</h3>
Constructs a SQL driver plugin. This is invoked automatically by
the <tt>Q_EXPORT_PLUGIN</tt> macro.

<h3 class=fn><a name="~TQSqlDriverPlugin"></a>TQSqlDriverPlugin::~TQSqlDriverPlugin ()
</h3>
Destroys the SQL driver plugin.
<p> You never have to call this explicitly. TQt destroys a plugin
automatically when it is no longer used.

<h3 class=fn><a href="qsqldriver.html">TQSqlDriver</a>&nbsp;* <a name="create"></a>TQSqlDriverPlugin::create ( const&nbsp;<a href="qstring.html">TQString</a>&nbsp;&amp;&nbsp;key )<tt> [pure virtual]</tt>
</h3>

<p> Creates and returns a <a href="qsqldriver.html">TQSqlDriver</a> object for the driver key <em>key</em>.
The driver key is usually the class name of the retquired driver.
<p> <p>See also <a href="#keys">keys</a>().

<h3 class=fn><a href="qstringlist.html">TQStringList</a> <a name="keys"></a>TQSqlDriverPlugin::keys () const<tt> [pure virtual]</tt>
</h3>

<p> Returns the list of drivers (keys) this plugin supports.
<p> These keys are usually the class names of the custom drivers that
are implemented in the plugin.
<p> <p>See also <a href="#create">create</a>().
