Pre Save Observer

[ktkoh]

I am trying to implement a pre save observer. This is an example of the file. This works on the current model if I load the file after the model is open. However if I bring up a new model and then save it this observer does not see the save operation. Suggestions on how to make it work on each model I save??

require 'sketchup.rb'
# This is an example of an observer that watches the
# model save event.
module K2WS
class MyModelObserver < Sketchup;;ModelObserver
def onPreSaveModel(model)
UI.messagebox("PreSaveObserver")
end
end
# Attach the observer.
Sketchup.active_model.add_observer(MyModelObserver.new)	
end # K2WS

When you start a new model, or open a model the existing model - the one with the observer attached is destroyed.

You need to attach an observer to the new model. Use an AppObserver to be notified when you open a model, or when you start a new model.

Thanks. That was just what I needed.

I'm glad it helped.

What I said is true on Windows because there is ever only one Model.

On a Mac you can have more than one model opened. But you still probably need to attach your observers when new models are created.
