All Implemented Interfaces:

QAbstractFactoryInterface, QAbstractStyleFactoryInterface, QtJambiInterface

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()
