Hei Juliana, i guess your idea is the best, to add a property to the Layer class (Layerable?) and then change the selection tool /method
I think we should apply this to the core as well ... if e.g.Ugo or Larry think the same stefan Juliana Barros wrote > Thanks for your help! > I Think I will change the OpenJump source but I will make a simple > modification specifically at Layer class and CursorTool. > > > On 8/29/06, * Sunburned Surveyor* <[EMAIL PROTECTED] > <mailto:[EMAIL PROTECTED]>> wrote: > > Thanks for the extra information.
