gps update timeout

[GoogleCodeExporter]

hi

i have added timeout for gps updates if user moving the map.
you need gps or gps simulator to see changes.

enable "gps center" mode and try to move the map. map will not centered several 
seconds. after timeout it will function as user selected.

Please add your changes to the trunk, in that way we can discuss the details.

This should be a new GPS mode it should not affect the behavior of the existing 
modes

hi

i have add changes to trunk.

and starting from r1011 there is following errors:

1. maps.py in gps_callback(self, coord, mode)
location is updated only first time.
i've commented out code that produce error

2.
Traceback (most recent call last):
  File "maps.py", line 744, in expose_cb  self.draw_overlay()
  File "maps.py", line 835, in draw_overlay  self.showMarkers, self.gps
  File "gmapcatcher\widDrawingArea.py", line 240, in draw_overlay
    draw_image(location, img, GPS_IMG_SIZE[0], GPS_IMG_SIZE[1])
NameError: global name 'draw_image' is not defined

even after fixing it current gps location marker does not drown in correct 
place.

could you provide more complete tracebacks than that, to allow us to identify 
the precise bugs?

hopefully I've identified the bugs now; as my gpsd seems to have difficulty 
sending its messages to gmapcatcher perhaps you could check

In r1023 what you commented "## following code does not working" is something 
that does not affect the program and will be useful very soon.

I been looking at the code and I do not understand what you are trying to do... 
your changes should NOT affect the behavior of GPS_CENTER or GPS_ON_SCREEN.

I just added a new option GPS_TIMEOUT and moved your code to the appropriate 
section, see r1026 for more details

check the attached screen shots of r1010 and r1011 with fixed bugs as r1024.
gps mode is "gps center".
red marker not in the center. it always on the left side starting from r1011

that's definitely an improvement; I'm thinking longer-term at some stage some 
kind of config setting - I seem fond of config settings :-D - as a modification 
of center/onscreen would be worthwhile, although definitely for now GPS_TIMEOUT 
sounds safest :-)

 After looking at the code & re-reading this issue, my guess is: 
You want to recenter the GPS marker IF AND ONLY IF the program has been idle 
for more than 3 seconds.

they are did not affected to the behavior of GPS_CENTER or GPS_ON_SCREEN.
yeah, my code is little bit ugly, but i will explain reason of this changes.

try to attach a gps with 1 sec update and set GPS_CENTER mode.
than try to scroll the map. map will flicks.
my code just adds small delay. if you release the dragged map, after 3 secs it 
will continue in normal GPS_CENTER or GPS_ON_SCREEN mode.

yeah, you are right.
only on map scrolling, not after zooming or after any other activity.

pokrash, could you check the centering of the gps marker now? Hopefully I found 
the bug

the GPS_TIMEOUT should be all good now, please take a look at r1028

gps marker position is correct now.

and i have one idea to replace marker to arrow pointing direction of moving.
but i think it's not so simple task.
there will need some coordinates filtering and a lot of testing.

best is to test before committing :-)

replace GPS marker to arrow pointing direction of moving = Issue 78
