initialize

Initialize a system window. Add label, stripes, etc., if desired


 

step

Do some periodic activity. Use startStepping/stopStepping to start and stop getting sent this message. The time between steps is specified by this morph's answer to the stepTime message. The generic version dispatches control to the player, if any. The nasty circumlocation about owner's transformation is necessitated by the flexing problem that the player remains in the properties dictionary both of the flex and the real morph. In the current architecture, only the top renderer's pointer to the player should actually be honored for the purpose of firing.


 

stepTime

Answer the desired time between steps in milliseconds. This default implementation requests that the 'step' method be called once every second.


 

wantsSteps

Return true if the model wants its view to be stepped. For an open system window, we give the model to offer an opinion


 

wantsStepsWhenCollapsed

Keep time up to date in title bar

initializeToStandAlone

Set up the receiver, created by a #basicNew and now ready to be initialized, as a fully-formed morph suitable for providing a graphic for a parts bin surrogate, and, when such a parts-bin surrogate is clicked on, for attaching to the hand as a viable stand-alone morph. Because of historical precedent, #initialize has been expected to handle this burden, though a great number of morphs actually cannot stand alone. In any case, by default we call the historical #initialize, though unhappily, so that all existing morphs will work no worse than before when using this protocol.

descriptionForPartsBin

If the receiver is a member of a class that would like to be represented in a parts bin, answer the name by which it should be known, and a documentation string to be provided, for example, as balloon help. When the 'nativitySelector' is sent to the 'globalReceiver', it is expected that some kind of Morph will result. The parameters used in the implementation below are for documentation purposes only!
