RE: [udig-devel] Adding a image layer
|
Hello,
I have been looking for it,
I think I should use SetLayerVisibilityCommand class, so I started to search for the correct command factory but no specific method to create a SetLayerVsibilityCommand class...
I have been searching in the udig api, package: net.refractions.udig.project.command
In this package I haven't found the class, so I started to search the AbstractCommand and UndoableMapCommand, since SetLayerVisibilityCommand extend/implement those classes, but no clue of the class I am searching for.
Any tip?
Sorry for being annoying asking all time...
Thank you in advance.

Try starting from a working example;
http://svn.osgeo.org/geotools/trunk/modules/plugin/imagemosaic/src/test/resources/org/geotools/gce/imagemosaic/test-data/rgb/
And then modify it based on what you learned.

THe ILayer interface is the read-only interface; in order to modify
something in a safe way you need to issue a command. When your command
is executed you have access to the internal read-write Layer
interfaces on which you can call setVisible.
Please review the developers guide section on commands for details.
