Some Notes on Internal Implementation (Mathematica Tutorial)

General issues about the internal implementation of Mathematica are discussed in "The Internals of Mathematica". Given here are brief notes on particular features. These ...

ExposeWidgetReferences (GUIKit Package Symbol)

ExposeWidgetReferences is an option to Widget which specifies a list of normally internal \:f3b5children widget reference names to include as publicly available instances.

IncludedScriptContexts (GUIKit Package Symbol)

IncludedScriptContexts is an option to GUIRun and related functions that can extend the active $ContextPath that Script blocks within a definition will use.

InitialArguments (GUIKit Package Symbol)

InitialArguments is an option to Widget which specifies the argument list to use when instantiating this widget definition.

InvokeThread (GUIKit Package Symbol)

InvokeThread is an option to GUIKit symbols which specifies what thread the invocation should execute on.

InvokeWait (GUIKit Package Symbol)

InvokeWait is an option to GUIKit symbols which determines whether a threaded invocation should wait for a result or continue on immediately without a response.

ReleaseMethod (GUIKit Package Symbol)

ReleaseMethod is an option to GUIRun and related functions that determines when a GUIObject is released.

WidgetLayout (GUIKit Package Symbol)

WidgetLayout is an option to Widget, WidgetReference, and WidgetGroup that contains suboptions controlling layout.

CoarserSetPartitionQ (Combinatorica Package Symbol)

CoarserSetPartitionQ[a, b] yields True if set partition b is coarser than set partition a; that is, every block in a is contained in some block in b.

CoxeterGraph (Combinatorica Package Symbol)

CoxeterGraph gives a non-Hamiltonian graph with a high degree of symmetry such that there is a graph automorphism taking any path of length 3 to any other.
