wingrass wx carto composer: adding north arrow causes Error and traceback

[hamish]

Hi,

testing latest 6.5svn nightly wingrass build.

If you open the wxGUI cartographic composer and pick 'add map element' then 'North Arrow' you get a pop-up Error message window (screenshot attached), twice, and the following different error message in the wxGUI command console module output window:

Traceback (most recent call last):

and no image selection gui window. On my linux it works.

(the first half of the above is very similar to the traceback error in #1959)

thanks, Hamish

ps- todo: replace those eps with native GRASS symbols

The first part is the same problem as in #1959. The second part is the same problem as with preview, try r56121.

This particular issue seems to be fixed but there is another error, see #1959 comment:3

Replying to annakrat:

This particular issue seems to be fixed but there is another error, see #1959 comment:3

I am closing this ticket, the remaining problem is in #1959
