+Base class for every context.
+Think of a Context-based class as "useful
+info associated to a context menu". Several context menu can be defined,
+each defining different information: because of these context menus being
+used in many modules, they are defined here.
+
+When context menu with a certain "context" associated appears, KDevelop core
+sends a notification signal and all plugins which receive this signal have
+the ability to add own items into the menu. For example, VCS plugin could
+add "commit" and "update" menu items to the context menu of a file.
+
+<b>How to use context from a plugin:</b>
+-# Create a popup menu in context menu event handler: @code KPopupMenu menu(this); @endcode
+-# Create a context: @code MyContext context(param). @endcode
+-# Fill a context menu: @code core()->fillContextMenu(&menu, &context); @endcode
+-# Show the popup menu: @code menu.exec(event->globalPos()); @endcode
+.
+In this example @em event is an object of QContextMenuEvent class which you have access
+to if you reimplement QWidget::contextMenuEvent method.
+
+<b>How to fill context menu from a plugin:</b>
+-# Create a @code contextMenu(QPopupMenu *, const Context *) @endcode slot in your plugin class.
+-# Connect KDevCore::contextMenu(QPopupMenu *, const Context *) signal to that slot in
+the constructor of your plugin:\n
+@code
+connect(core(), SIGNAL(contextMenu(QPopupMenu *, const Context *)),
+ this, SLOT(contextMenu(QPopupMenu *, const Context *)));
+@endcode
+-# Fill the menu in the slot you created, for example:\n
+@code
+if (context->hasType(Context::EditorContext))
+{
+ const EditorContext *econtext = static_cast<const EditorContext*>(context);
+ int id = popup->insertItem(i18n("My Menu Item 1"), this, SLOT(myMenuAction1()));
+ popup->setWhatsThis(id, i18n("What's this for my menu item 1"));
+}
+else if context->hasType(MyContext))
+{
+ int id = popup->insertItem(...
+ ...
+}
+...
