public abstract class QStylePlugin
extends QObject
implements QAbstractStyleFactoryInterface, QAbstractFactoryInterface

The QStylePlugin class provides an abstract base for custom QStyle plugins. QStylePlugin is a simple plugin interface that makes it easy to create custom styles that can be loaded dynamically into applications using the QStyleFactory class.

Writing a style plugin is achieved by subclassing this base class, reimplementing the pure virtual keys() and create() functions, and exporting the class using the Q_EXPORT_PLUGIN2() macro. See How to Create Qt Plugins for details.

Constructor Detail

QStylePlugin

public QStylePlugin()
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

public QStylePlugin(QObject parent)
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

protected QStylePlugin(QtJambiObject.QPrivateConstructor p)
This method is internal to Qt Jambi.

Method Detail

create

public abstract QStyle create(java.lang.String key)
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:

    List<String> keys()
    {
        List<String> keyList = new Vector<String>();
        keyList.add("Rocket");
        keyList.add("StarBuster");

        return keyList;
    }
    
QStyle create(String key) { String lcKey = key; if (lcKey.equals("rocket")) { return new RocketStyle(); } else if (lcKey.equals("starbuster")) { return new StarBusterStyle(); } return null; }

keys

public abstract java.util.List<java.lang.String> keys()
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.

fromNativePointer

public static QStylePlugin fromNativePointer(QNativePointer nativePointer)
