The contents of the GPSMan data-base are shown in lists, one per each item type. Item names, which are unique, are presented in alphabetical order.
List menus contain the actions
allowed on the list, like
creating
a new
item, opening an existing one,
clearing the list,
reading/writing items, and
counting the number of items in the list.
The menu for the groups list is a little different and is described
below.
Loading operations read all the data in a GPSMan file
irrespective of from what menu the operation was launched. Laps
in a file will be ignored unless
the support for laps is active.
To open an item
for
editing (only possible when no other
item of the same kind is being edited) or viewing its data, use
the appropriate menu entries in the sub-menus of the
An edit/show window for an item will be closed and re-opened in case
there is a read operation redefining it.

name (in the corresponding list) with the mouse right-button, or use
the A read operation redefining items that are currently on the map will
cause the map to be updated in order to keep it consistent with the
new definitions.
Pressing a key on a list
will scroll it to make visible the
first element whose initial character is the same or higher in ASCII order
than the key character. Note that this is case sensitive (i.e.,
Hidden information
is kept (in the data-base
and in files) associated to an item data that has been read in (from a
file, or from the receiver) when that information cannot be
edited using GPSMan. This is done mainly with data fields that are
not of general use, and provides a means of restoring the data item
back to any receiver that works with the same communication protocols,
without loosing information. When the item data is modified its
hidden information is either deleted, or kept, or acted upon as the
user sees fit, according to an option. Keeping the hidden information
may cause incoherent items to be created and therefore should be used
with care.
Hidden information in a waypoint or a track can be
displayed from their edit/show windows (a button for this is created
only when such information exists).
Saving the program state
when exiting is controlled by an option that may inhibit this feature,
do the saving if the user confirms it, or do it without asking. When
saving the state, files in the user data directory are created that
contain the current data-base, the map state and information on which
edit/show windows are currently being used. No information is kept on
The saved state is automatically loaded
when GPSMan is launched and finds a saved state file in the user
directory. There is an option to control whether to delete saved state
files after the state being restored; it can be set in the same way as
the save state option. In any case GPSMan automatically overwrites
saved state files when saving a new state, and it is therefore a good
idea to save important data to a file before quitting the program.
Note that in command-line mode the saved state is not restored
and the state is not saved.
Other information can be retrieved from the receiver and
displayed as text that can then be saved to a file, without being
stored in the data-base.
At present this is the case with GPS almanac data
(only implemented for Garmin receivers). The following is a list of
all the possible fields, the actual set used by each receiver
depending on the protocol it uses:
If the satellite identification numbers are missing, the order of the
lines is the one provided by the receiver and is expected to follow
the satellite numbers from 1 to 32.
