Re: [udig-devel] How can I handle changing of layers projection programm

[Jody Garnett <jody.garnett@xxxxxxxxx>]

Well I suspect there is a command .. since any change to Map/Layer stuff needs to be done via a command or we deadlock.

Not sure; let us look at how that operation does.... 

Looks like CRSPropertyPage has a applyCoordinateReferenceSystem method with the following:

UndoableComposite commands=new UndoableComposite();

List<MapCommand> commandList = commands.getCommands();

commandList.add(new SetLayerCRSCommand(layer, crs));

...

layer.getMap().sendCommandASync(commands);            

Since you just have one command; there is no need to do the UndoableComposte() thing.

Hi,

 

How can I handle changing of layers projection programmatically?

(I selected Properties of necessary Layer and in projection tab changed CRS. Can I handle changing of CRS in my code? Maybe add some listener?)

 

Thanks
