|
||
|
|
|
||
|
|
|
||
|
|
The QSqlDriverPlugin class provides an abstract base for custom <a href="qsqldriver.html">QSqlDriver</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 Qt.
|
||
|
|
<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 Qt 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>.

|
||
|
|
<h3 class=fn><a name="QSqlDriverPlugin"></a>QSqlDriverPlugin::QSqlDriverPlugin ()
|
||
|
|
</h3>
|
||
|
|
Constructs a SQL driver plugin. This is invoked automatically by
|
||
|
|
the <tt>Q_EXPORT_PLUGIN</tt> macro.
|
||
|
|
|
||
|
|
<h3 class=fn><a name="~QSqlDriverPlugin"></a>QSqlDriverPlugin::~QSqlDriverPlugin ()
|
||
|
|
</h3>
|
||
|
|
Destroys the SQL driver plugin.
|
||
|
|
<p> You never have to call this explicitly. Qt destroys a plugin
|
||
|
|
automatically when it is no longer used.
|
||
|
|
|
||
|
|
<h3 class=fn><a href="qsqldriver.html">QSqlDriver</a> * <a name="create"></a>QSqlDriverPlugin::create ( const <a href="qstring.html">QString</a> & key )<tt> [pure virtual]</tt>
|
||
|
|
</h3>
|
||
|
|
|
||
|
|
<p> Creates and returns a <a href="qsqldriver.html">QSqlDriver</a> object for the driver key <em>key</em>.
|
||
|
|
The driver key is usually the class name of the required driver.
|
||
|
|
<p> <p>See also <a href="#keys">keys</a>().
|
||
|
|
|
||
|
|
<h3 class=fn><a href="qstringlist.html">QStringList</a> <a name="keys"></a>QSqlDriverPlugin::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>().
