Based on what I can find in the code here are my options:
1) Modify getShapeProperty to include a getStateCmd option. Sounds simple, but
I find this access method strange as it duplicates methodologies built into the
programming language. Isn't it easier to define public getter functions within
objects or make objects publicly readable? This has the additional advantage
that if getters have javadoc attached to them it is much easier to figure out
what the things you are looking for are called.
2) My present preference (lacking public getter functions) is to use the
viewer.getShapeManager() function to grab the list of shapes and pick the data
I want out of the data structure. Of course, when the data structure is
changed my functions will break.
3) Add public getter functions to ShapeManager. It looks like it might have to
be abstract for both of the things I am most interested in (stateCmd and
boundBoxCorners), because different shapes have different info. A prime
example is drawn polygons for which I will need to check all the vertices to
define the boundbox as that does not appear in the data structure.
I think options 2 & 3 are something Bob is trying to avoid. Bob, can you
explain why?
Any thoughts?
