PackageManager - Browser Integration

Web-Browser Modification

Upon downloading a descriptor file of mime type, application/qtopia-package, the browser needs to:

1. Create an instance of QDSServices with the requestDataType, application/qtopia-package and attribute, install. (The responseDataType should be "*").
2. The QDSServices object should contain a QDSServiceInfo object corresponding to PackageManager, use that to create a QDSAction object.
3. Create a QDSData object with the downloaded qpd file and application/qtopia-package mime type.
4. Invoke the exec() function of the QDSAction object with the QDSData object as a parameter. Via the services framework, this will invoke PackageManager to begin the installation process and prompt the user to confirm installation.

There are two ways to add this functionality to a web browser:

1. Integrate it into the web browser code (this may not always be possible due to licensing issues or if the web browser application is in binary format).
2. Create an application invoked by the browser on recognition of a particular mime type. Contemporary browsers such as Firefox or Opera can be configured in this way. After the Qt Extended package descriptor file is downloaded it is passed as a parameter to this application, which implements the above functionality of finding and invoking the PackageManager service.
