08/04/08:

08/03/08:

23:53 Changeset [432] by gkronber

removed the button and methods for manual recalculation of min tree bounds introduced with r423 because it soon won't be needed anymore
GPOperatorGroup adds event-handlers to SubOperatorTypeConstraints on the operators added to the library to automatically update min tree size and height when any of them is changed.

(ticket #225)

23:33 Changeset [431] by gkronber

removed the 'AllowedSubOperators' variable for functions because the original intention was to cache the list of allowed sub-functions which is actually determined by a tree of constraints. However the original idea was never fully implemented so up to now any function in the library was allowed for any other function as long as it was not a terminal (also defined by constraints on the arity). The 'AllowedSubOperators' variable is not necessary at all when we defined the set via constraints. The SubOperatorsConstraintView allows draging of functions from the library into the constraint.

Next step: automatic adaption of SubOperatorsConstraints of functions in the library when new functions are added or existing entries removed.
(ticket #225)

23:14 Changeset [430] by gkronber

removed 'TypeIds' for functions (also a relic of an old design) (ticket #225)
