Re: [udig-dev] ProjectRegistryImpl and synch call in Display Thread

[Frank Gasdorf <fgdrf@xxxxxxxxxxxxxxxxxxxxx>]

That was my guess as well. Otherwise I found OpenProjectElementCommand that can be executued in DisplayThread  (PlatformGIS.syncInDisplayThread / asyncInDisplayThread). Did I understood you correctly : On startup of uDig if emf maybe restores projects & maps it should open projects and its maps automatically? 

Where is the entry point to look at how projects and maps are restored? Would help to clarify and test the approach calling it without invoking  "setCurrentProject"

Thinking about it, In general we try do any heavy lifting out of the display thread (to avoid blocking the UI) and then call event UI event notification in the event thread.

I expected getProject() *may* have to load the project, if it was currently closed

Hello everybody,

I'm wondering about the implementation of ProjectRegistryImpl.getProject() since it internally synchronize calls in Display thread.

After creating a Project the following block set the current project (notifies E-Models) and add the project itself to the registry:

PlatformGIS.syncInDisplayThread(new Runnable() {
                public void run() {
                    try {
                        setCurrentProject(newProject);
                        registry.getProjects().add(newProject);
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                }
            });

What I expected to get is a simple project object that has been registrated correctly to work on it pragmatically (create a map, etc.) Once all these tasks are finished I'd like to set and open newly created map.

Is there any other reason (EMF, etc.) I'm not aware to call this synchronously in Display Thread?

Thanks a lot

- Frank
