Detailed Description

The QWebPluginFactory class is used to embed custom data types in web pages.

The HTML <object> tag is used to embed arbitrary content into a web page, for example:

<object type="application/x-pdf" data="https://www.copperspice.com/sample.pdf" width="500" height="400"></object>

CsWebKit will natively handle the most basic data types like text/html and image/jpeg, but for any advanced or custom data types you will need to provide a handler yourself. QWebPluginFactory is a factory for creating plugins for QWebPage, where each plugin provides support for one or more data types. A plugin factory can be installed on a QWebPage using QWebPage::setPluginFactory().

Note
The plugin factory is only used if plugins are enabled through QWebSettings.

You provide a QWebPluginFactory by implementing the plugins() and the create() methods. For plugins() it is necessary to describe the plugins the factory can create, including a description and the supported MIME types. The MIME types each plugin can handle should match the ones specified in in the HTML <object> tag of your content.

The create() method is called if the requested MIME type is supported. The implementation has to return a new instance of the plugin requested for the given MIME type and the specified URL.

The plugins themselves are subclasses of QObject, but currently only plugins which are based on either QWidget or QGraphicsWidget are supported.

Constructor & Destructor Documentation

QWebPluginFactory::QWebPluginFactory ( QObject parent = 0)
explicit

Constructs a QWebPluginFactory with parent parent.

QWebPluginFactory::~QWebPluginFactory ( )
virtual

Destructor.

Method Documentation

QObject * QWebPluginFactory::create ( const QString mimeType,
const QUrl url,
const QStringList argumentNames,
const QStringList argumentValues 
) const
pure virtual

Implemented in subclasses to create a new plugin that can display content of the MIME type given by mimeType. The URL of the content is provided in url. The returned object should be a QWidget.

The HTML object element can provide parameters through the <param> tag. The name and the value attributes of these tags are specified by the argumentNames and argumentValues string lists.

For example:

<object type="application/x-pdf" data="https://www.copperspice.com/sample.pdf" width="500" height="400">
<param name="showTableOfContents" value="true" />
<param name="hideThumbnails" value="false" />
</object>

The above object element will result in a call to create() with the following arguments:

ParameterValue
mimeType"application/x-pdf"
url"https://www.copperspice.com/sample.pdf&quot;
argumentNames"showTableOfContents" "hideThumbnails"
argumentValues"true" "false"
Note
Ownership of the returned object will be transferred to the caller.
QList< Plugin > QWebPluginFactory::plugins ( ) const
pure virtual

This function is reimplemented in subclasses to return a list of supported plugins the factory can create.

Note
Currently, this function is only called when JavaScript programs access the global plugins or mimetypes objects.
void QWebPluginFactory::refreshPlugins ( )
virtual

This function is called to refresh the list of supported plugins. It may be called after a new plugin has been installed in the system.
