Hi, I've had the same problem that Andrew Mason and Javier founded, with pointed features that are not repainted after zoom. And I didn't find a solution. =20 -----Mensagem original----- De: geo...@li... [mailto:geo...@li...] Em nome de geo...@li... Enviada em: quarta-feira, 13 de julho de 2005 00:08 Para: geo...@li...

StatusBar format is independant of the map CoordinateReferenceSystem=20 (transformations are performed automatically as needed). However, the=20 455700=BA25,5 format suggest that there is something wrong with the CRS=20 used. I guess that 445700,255 is some projected coordinate like UTM, but = the 455700=BA25,5 string suggest that StatusBar believe that the=20 underlying CRS is geographic. If you have created a MapPane (or=20 StyledMapPane), make sure that the data used for creating the layers=20 uses the right ProjectedCRS. Otherwise, a patch for displaying angles like 445700,255 is: statusBar.getCoordinateFormat().setAnglePattern("D.ddd"); But don't do if you can avoid: I suggest to check the CRS in the layers=20 given to MapPane instead.
