The ServerInterface allows the user interface of the launcher to be customized to suit the device. For a PDA style device, the default launcher is strongly recommended, however specialist devices may choose to provide a launcher better suited to the application. The launcher is fixed for any particular device and is not loaded as a plugin. Launcher interfaces must be compilied into the server by editing server.pro and server.cpp. */ /*! \fn ServerInterface::createGUI() Implement this function to create the custom launcher UI. */ /*! \fn ServerInterface::destroyGUI() Implement this function to destroy the custom launcher UI. All resources allocated by createGUI() must be released. */ /*! \enum ServerInterface::ApplicationState The ApplicationState enum type specifies the state of an application. The possible values are: <ul> <li> \c Launching - the application has been requested, but is not yet running. <li> \c Running - the application is running. <li> \c Terminated - the application has been terminated. </ul> */ /*! \fn ServerInterface::applicationStateChanged(const QString& name, ApplicationState state) The application \a name has changed state to \a state. This can be used to show launch notification and update a list of running applications. */ /*! \fn ServerInterface::typeAdded(const QString& type, const QString& name, const QPixmap& pixmap, const QPixmap& bgPixmap) An application category \a type has been added, for example "Games". \a name is the translated name of the category. \a pixmap and \a bgPixmap are small and large icons for the new type. Types can be added or removed at any time, for example, when a storage card containing a non-standard category is inserted or removed. \sa typeRemoved() */ /*! \fn ServerInterface::typeRemoved(const QString& type) An application category \a type has been removed. Types can be added or removed at any time, for example, when a storage card containing a non-standard category is inserted or removed. \sa typeAdded() */ /*! \fn ServerInterface::applicationAdded(const QString& type, const AppLnk& app) Add an application \a app of type \a type to the launcher. \sa applicationRemoved() */ /*! \fn ServerInterface::applicationRemoved(const QString& type, const AppLnk& app) Remove an application \a app of type \a type from the launcher. \sa applicationAdded() */ /*! \fn ServerInterface::allApplicationsRemoved() Remove all applications from the launcher. */ /*! \fn const AppLnkSet &ServerInterface::appLnks() Returns the current set of available applications. */ /*! \fn ServerInterface::documentAdded(const DocLnk& doc) Add a document \a doc to the launcher. \sa documentRemoved() */ /*! \fn ServerInterface::documentRemoved(const DocLnk& doc) Remove a document \a doc to the launcher. \sa documentAdded() */ /*! \fn ServerInterface::documentChanged(const DocLnk& oldDoc, const DocLnk& newDoc) Change document properties of existing document \a oldDoc to \a newDoc. */ /*! \fn ServerInterface::allDocumentsRemoved() Remove all documents from the launcher. */ /*! \fn ServerInterface::storageChanged(const QList<FileSystem> &) A filesystem has been added or removed. */ /*! \fn ServerInterface::applicationScanningProgress(int percent) The system is scanning for installed applications. \a percent provides the percentage of the filesystems scanned.

The widget is placed according to the order that it was docked, its sizeHint() and whether previously docked widgets are visible. The desktop area available to QWidget::showMaximized() will exclude any visible docked widgets. For example, if a widget is docked at the bottom of the screen, its sizeHint() will define its height and it will use the full width of the screen. If a widget is then docked to the right, its sizeHint() will define its width and it will be as high as possible without covering the widget docked at the bottom. This function is useful for reserving system areas such as taskbars and input methods that should not be covered by applications. */ ServerInterface::~ServerInterface() { } void ServerInterface::dockWidget( QWidget *w, DockArea placement ) { static LayoutManager *lm = 0; if ( !lm ) lm = new LayoutManager; lm->addDocked( w, placement ); } const AppLnkSet& ServerInterface::appLnks() { return *DocumentList::appLnkSet; } #include "serverinterface.moc" |
