information presented in the list, a calendar, placed above it,
gives the user the possibility to filter the items by date.
After pressing an item of the list, which could be a GSM
cell or a GPS coordinate, the mTrackerMap instantly loads a
map from Google Maps with a small marker that represents
the selected item. Moreover, the map will be refreshed if the
user chooses another item from the list.
The File button placed at the Menu Bar provides not only
the application termination but also refreshes the main
window.
