* type of m_applications is QMap<QString, uint>.

m_applications = m_installer->applications();
/* Get List of application names

m_appNames = m_applications.keys();
/* Get List of application UID in decimal.
*type of m_appUID is QList<uint>

m_appUID = m_applications.values();
for (int i = 0; i < m_appNames.count(); i++)
QString str;
/* convert UID from decimal to hex and then string. */
/* append name and UID to string */
QString string(" UID:"+ str);
/* append string to list widget to display on screen */
/* Let's make the UI scale so that we can scroll it. */
QScrollArea* scrollArea = new QScrollArea;
/* setCentralWidget() takes ownership of scrollArea and deletes it at the appropriate time. so no need to delete scrollArea */


The code snippet is expected to show a list of all installed applicationa with its UID.
