|

| 46 |
|
|---|
| 47 |
|
|---|
| 48 | The QStylePlugin class provides an abstract base for custom <a href="qstyle.html">QStyle</a> plugins.
|
|---|
| 49 | <p>
|
|---|
| 50 | <p> The style plugin is a simple plugin interface that makes it easy
|
|---|
| 51 | to create custom styles that can be loaded dynamically into
|
|---|
| 52 | applications with a <a href="qstylefactory.html">QStyleFactory</a>.
|
|---|
| 53 | <p> Writing a style plugin is achieved by subclassing this base class,
|
|---|
| 54 | reimplementing the pure virtual functions <a href="#keys">keys</a>() and <a href="#create">create</a>(), and
|
|---|
| 55 | exporting the class with the <tt>Q_EXPORT_PLUGIN</tt> macro. See the
|
|---|
| 56 | <a href="plugins-howto.html">plugins documentation</a> for an
|
|---|
| 57 | example.
|
|---|
| 58 | <p>See also <a href="plugins.html">Plugins</a>.

|
|---|
| 61 | <h3 class=fn><a name="QStylePlugin"></a>QStylePlugin::QStylePlugin ()
|
|---|
| 62 | </h3>
|
|---|
| 63 | Constructs a style plugin. This is invoked automatically by the
|
|---|
| 64 | <tt>Q_EXPORT_PLUGIN</tt> macro.
|
|---|
| 65 |
|
|---|
| 66 | <h3 class=fn><a name="~QStylePlugin"></a>QStylePlugin::~QStylePlugin ()
|
|---|
| 67 | </h3>
|
|---|
| 68 | Destroys the style plugin.
|
|---|
| 69 | <p> You never have to call this explicitly. Qt destroys a plugin
|
|---|
| 70 | automatically when it is no longer used.
|
|---|
| 71 |
|
|---|
| 72 | <h3 class=fn><a href="qstyle.html">QStyle</a> * <a name="create"></a>QStylePlugin::create ( const <a href="qstring.html">QString</a> & key )<tt> [pure virtual]</tt>
|
|---|
| 73 | </h3>
|
|---|
| 74 |
|
|---|
| 75 | <p> Creates and returns a <a href="qstyle.html">QStyle</a> object for the style key <em>key</em>. The
|
|---|
| 76 | style key is usually the class name of the required style.
|
|---|
| 77 | <p> <p>See also <a href="#keys">keys</a>().
|
|---|
| 78 |
|
|---|
| 79 | <h3 class=fn><a href="qstringlist.html">QStringList</a> <a name="keys"></a>QStylePlugin::keys () const<tt> [pure virtual]</tt>
|
|---|
| 80 | </h3>
|
|---|
| 81 |
|
|---|
| 82 | <p> Returns the list of style keys this plugin supports.
|
|---|
| 83 | <p> These keys are usually the class names of the custom styles that
|
|---|
| 84 | are implemented in the plugin.
|
|---|
| 85 | <p> <p>See also <a href="#create">create</a>().
