Hi,
I am using gmf to create a modelling tool. The tool will draw nodes within
nodes to any level. They represent states within a statechart. The states
are drawn as boxes either with a solid line border or a dashed line
border. States have a field called parallel which is a boolean. If
parallel is true for a state then all of the states placed within it
should be drawn with a dashed border alternatively they should be drawn
with a solid border. I don't know how to implement this. at the moment
states have a single figure descriptor for drawing rectangles with solid
line borders. Do i have to create 2 figure descriptors for states, one for
drawing rectangles with a solid line border and one for drawing rectangles
with a dashed line border ? And then how do I force the correct one to be
used depending on the value of the field parallel in the parent state.
Thanks

Lishan

Currently yes.

You have to create two node mappings one sub-state with solid border and one
for the sub-state with dashed one + (OCL) constraint checking parent.parallel
property.
