Detailed Description

manages recently used resources

pqRecentlyUsedResourcesList manages recently used resources, such as data files, state files, etc. When user performs an action (e.g. loading of data, loading of state file) that should be saved to the recently used resource list, simply add it using pqRecentlyUsedResourcesList::add(). One stats with the pqServerResource obtained from the server on which the action was performed and the can add meta-data to it, as needed e.g.

pqServer* server = pqActiveObjects::instance().activeServer();
pqServerResource resource = server->getResource();
resource.setPath(...);
resource.addData("foo1", "bar1");
resource.addData("foo2", "bar2");
pqApplicationCore* core = pqApplicationCore::instance();
core->recentlyUsedResources().add(resource);

Now, applications can use pqRecentFilesMenu (or something similar) to show these resources in some menu or other UI element.

pqRecentlyUsedResourcesList itself doesn't handle reloading the resource from the list. That is left to the application. pqRecentFilesMenu, for example, uses implementations of pqRecentlyUsedResourceLoaderInterface registered with the pqInterfaceTracker to attempt to load the resource.
