 Once upon a time I was a python newbie, and there are many many things a newbie could 
do, if you are interested we could help you get started...

I started working on some tooltips on Issue 36, take a look that might get you 
going.

Now that I think about it, the "map" is a gtk.DrawingArea() and we draw the 
tiles, 
marker & GPS on top of it.
 Honestly I have no idea if a tooltip can be connected to a section of the 
DrawingArea; we could potentially draw out own "tooltip" but are we reinventing 
the 
wheel?

 I will recommend you to look at what other project are doing see if it can be incorporated.

the drawingArea object cannot connected to a tooltip
i thing i have to implement a custom widget with draws and store the data in a
tooltip. i haven't got the howto to this.
is it posible to but a button on the map with x and y coordinates?

a workaround was to add a mouse event (java=listener) and on click i calculate 
the
coordinates with the resolution and the mouseposition. if there is a marker i 
display
the information in a textbox!

what's your opinion?

the data for the tooltip could be read from the "markers" file see:
def read_file(strInfo, filePath): 
http://code.google.com/p/gmapcatcher/source/browse/trunk/src/fileUtils.py

Of course there is a way to display any widget at any location  gtk.Fixed()
this is an example:
http://www.zetcode.com/tutorials/pygtktutorial/customwidget/

we already have many "events" (signals is the proper name) in the drawing area, 
you 
could try one of those, see all the "da.connect(" in the def 
__create_right_paned(self):
http://code.google.com/p/gmapcatcher/source/browse/trunk/maps.py

Have Fun...

thx 4 the links!

can i get some help with the maputil "class"?
i have the mouse coordinats x,y and i would have long and lat.
so i calc. the offset beween the mouseposition and center.
i get the coordinats from the center but i don't know the scale for 
multipication the
offset. is it km_per_pixel(coord)??

is this the right way to get the mouse coordinats?

If I understand correctly, you want to convert from "mouse coordinats x,y" to 
"long 
and lat"

I give you a hint :)

 There are a few times when we use the "mouse coordinats" such as when user double 
clicks on the Drawing Area to Zoom In in that case we do_scale(to the pointer).

Is it OK if I add you as a developer to the team?

Let's take a step back...

We have 2 things that we need to compare:
 - the (x, y) coordinates from mouse
 - the (Lon, Lat) from the marker 

I will recommend you converting the Marker to (x, y) coordinates, we already do 
that 
when we draw the markers, look at def draw_overlay.

hope that helps you
