Detailed Description

ApplicationPackageMonitor listens dbus signals from Package Manager and watches installer-extra folder to receive info on package installation states and signaling relevant changes.

Some events may be communicated through both dbus signal and changes in desktop entries. This can lead to same package having multiple signals for same event (like progress error). Signal listener is responsible for handling such cases.

(eg. emits operationError() for all the packages in 'broken' state)

Definition at line 119 of file applicationpackagemonitor.cpp.

{
    QStringList keyList(dataStore->allKeys());

    foreach (QString key, keyList) {
        if (key.contains(PACKAGE_PREFIX)) {
            QString desktopEntryPath = dataStore->value(key).toString();
            QString state = dataStore->value(DESKTOPENTRY_PREFIX + desktopEntryPath).toString();
            if (state == PACKAGE_STATE_BROKEN) {
                // emit operation error for a broken package
                emit operationError(desktopEntryPath, QString());
            } else if(state == PACKAGE_STATE_DOWNLOADING) {
                emit downloadProgress(desktopEntryPath, 0, 0);
            } else if(state == PACKAGE_STATE_INSTALLING) {
