QStylePlugin Class Reference

Member Function Documentation

QStylePlugin::QStylePlugin ( QObject * parent = 0 )

Constructs a style plugin with the given parent.

Note that this constructor is invoked automatically by the Q_EXPORT_PLUGIN2() macro, so there is no need for calling it explicitly.

QStylePlugin::~QStylePlugin ()

Destroys the style plugin.

Note that Qt destroys a plugin automatically when it is no longer used, so there is no need for calling the destructor explicitly.

QStyle * QStylePlugin::create ( const QString & key ) [pure virtual]

Creates and returns a QStyle object for the given style key. If a plugin cannot create a style, it should return 0 instead.

The style key is usually the class name of the required style. Note that the keys are case insensitive. For example:

 QStringList MyStylePlugin::keys() const
 {
     return QStringList() << "Rocket" << "StarBuster";
 }

 QStyle *MyStylePlugin::create(const QString &key)
 {
     QString lcKey = key;
     if (lcKey == "rocket") {
         return new RocketStyle;
     } else if (lcKey == "starbuster") {
         return new StarBusterStyle;
     }
     return 0;
 }

See also keys().

QStringList QStylePlugin::keys () const [pure virtual]

Returns the list of style keys this plugin supports.

These keys are usually the class names of the custom styles that are implemented in the plugin.
