Re: [Geotools-gt2-users] problem using JMapFrame and ToolBar

[Ludji A. <lud...@al...>]

Hello Michael thanks for answer me.

I'm running and application that hold the Toolbar on JMapFrame like 
SelectionLab.java and the problem happens with any shapefile. My own 
shapefile and all shapeFile I've dowloaded from your site for the tutorial 
for example countries.shp references on ImageLab tutorial for Udig sample 
dataset.

I think it's happens when i use this lines in my code :

map.addLayer(layer);
mapFrame = new JMapFrame(map);
mapFrame.enableToolBar(true);   <----- the line that produce the problem (in 
my opinion)
mapFrame.enableStatusBar(true);

Regards,

Ludji
