Hello Leyan.
Thanks for query.
I will try to explain what I want to display but first will need to explain how the grid reference system (British National Grid) for Great Britain works.
Please refer to attached pic.
Here we go.
1 Great Britain is divided into a series of 100KM X 100KM grid squares.
2 Each square has a 2 digit number and pair of letters.
3 For example :- Grid square SJ is numbered 33.
4 Lets imagine you want to quote a grid reference for the southwest corner of grid square SJ.
5 This can be quoted 2 ways :- SJ 000,000 OR 3000,3000.
6 The same applies to any other grid square.
7 For example, the southwest corner of grid square SP could be quoted as SP 000,000 OR
4000,2000.
Currently QGIS will only display co ordinates in numeric format but it would be nice to have the option for displaying alpha numeric format.
Hope this makes sense.
If not I will try again.
Regards
Geoff

Where those "coordinates" should appear, in the layout composer? in the canvas?

Hello
Coordinates appear in canvas view at bottom of screen.(Please see attached screen shot 1).
Coordinates also appear in composer if I add a grid. (Please see attached screen shot 2).
On both attached pics, coordinates for the red marker is located at '400913, 300124'.
Taking the first digit of each coordinate gives the number 43.
Number 43 is grid square 'SK' when using the British National Grid.
So using the British National Grid, coordinates for the red marker could also be quoted as
'SK 00913, 00124'.
Hope this makes sense.

while it seems it can be useful for a specific use case, it don't don't know if/how this can be generalized in order to work for any user. This functionality seems best fitted for a plugin, don't you think?

Hello Giovanni.
Thanks for getting involved.
I think my suggestion would be useful but only for a very few users.
Must agree with you that perhaps a plug in would be the best solution.
I know nothing about writing plug ins but maybe this would be a good chance to attempt writing my first plug in.

so don't get me wrong if I close this ticket. Maybe I'm missing some point on how this suggestion can be useful for any Q(GIS) user and eventually a developer will reopen this. Meanwhile if you need you can ask for help about the plugin in the users/developers mailing list or contact one of the many companies that offer commercial support http://qgis.org/de/site/forusers/commercial_support.html

cheers!
