[ve-dev] Read/Write of complex LayoutManager values

[Gerald Rosenberg <gerald@xxxxxxxxxx>]

Thanks for the excellent help... FormLayoutSwitcher is essentially
done.

Now working on a simple FormLayoutPolicyEdit -- I see how to read/write
simple bean properties to the layoutmanager using INumberBeanProxy and
IStringBeanProxy.  However, I need to be able to access a property
with a more complex type:

public int[][] getColumnGroups()

and

public ColumnSpec getColumnSpec(int columnIndex)

So the first question is: is there an IObjectBeanProxy or some
equivalent?  If not, how do I extract existing layoutmanager
constructor arguments (which is what defines the form of the layout
format)?

FormLayout layout = new FormLayout(

"right:pref, 6dlu, 50dlu, 4dlu",  // 4 columns

"pref, 3dlu, pref, 3dlu, pref");  // 5 rows

---------------

Second question is: is there a way to invoke a non-bean (is/get/set)
based method on the layoutmanager?  Not essential, but it would be
helpful to be able to use layoutmanager methods of the form:

public void insertColumn(int columnIndex, ColumnSpec columnSpec)

and

public void removeColumn(int columnIndex)

----------------

The final question involves working with existing constraint objects -- I
will need to enumerate the components in the container and then inspect
the fields of the corresponding constraint object to extract the current
constraint values.  Something like:

...
List cclist = ...  // accumulator for constraint values 
while
(childs.hasNext()) { // where childs is an interator over the List
of container components

EObject constraintComponent = InverseMaintenanceAdapter.getIntermediateReference((EObject)

getContainerBean(), sfComponents, sfConstraintComponent, (EObject) childs.next());

// this is the unknown part vvvvvv

CellConstraints constraint = ????(constraintComponent);

cclist.add(constraint.gridX);

cclist.add(constraint.gridY);

cclist.add(constraint.gridWidth);

cclist.add(constraint.gridHeight);

}

Explanations and/or pointers to exemplary source in the project would be
appreciated.
