[udig-devel] RE: Loading a Udig project programatically (Mario Nu?ez Jimenez)
|
Hi Mario,
Here is my code: I open an existing project ,or create one if not found.
Then I check if new layers exists or are (un)authorized for a particular
user. So the user's layers are customisable by an administrator. List of
authorized layers comes from a properties files for test purpose.
the method 'LoadProject.createProject();' is called into
ApplicationWorkbenchWindowAdvisor.postWindowOpen()
the method 'LoadProject.UpdateProject();' is called into
MapOpenInterceptor.run(Map map)
I hope it helps.
Regards,
Frederick.
