Overview

Just like firefox informs you of updates to your addons, KNewStuff can let you check for updates since KDE SC 4.5.

There is an example in kdeexamples.

DownloadManager

The class in question is DownloadManager.

Use an instance of DownloadManager in your class: m_downloadManager = new KNS3::DownloadManager("plasmoids.knsrc", this);

   connect(m_downloadManager, SIGNAL(searchResult(KNS3::Entry::List)), this, SLOT(slotUpdatesFound(KNS3::Entry::List)));
   connect(m_downloadManager, SIGNAL(entryStatusChanged(KNS3::Entry)), this, SLOT(entryStatusChanged(KNS3::Entry)));
   m_downloadManager->checkForUpdates();

The entryStatusChanged signal informs you when you installed an entry. If you don't want to make use of that possibility, you can ignore the signal. void UpdateChecker::slotUpdatesFound(const KNS3::Entry::List& updates) {

   m_updates = updates;
   foreach (const KNS3::Entry& entry, updates) {
       kDebug() << entry.name();
   }

} To install an entry you can show the download dialog or do it without the dialog by using: m_downloadManager->installEntry(entry);
