Question

Peggy,
You CAN trap a SHIFT-CLICK for multiple selection on array fields. We use Express.
ArrayWidget is an attribute in the ExpressArrayWindow class of type ArrayDesc. If you
don't use Express then trap the childClick event on the ArrayField(I think).
when ArrayWidget.Field.ChildClick(modf = modifier) do
if ( modf = KM_SHIFT) then // Shift Key was pressed

The first is from John Jamison and says:
Simple, easy answer - yes and no. You can't do multiple selection in the
standard way ("shift click"). But you can develop "select-act" user
interactions where the action takes place on multiple "selected" items.
The typical suggested workarounds are to embed checkboxes as attributes in
the outline or array field, and use the checkbox to delineate "selected"
rows from "unselected" ones.
Another mechanism for array fields is to change the row color. How to do
this is detailed in a tech note (it is not easy). Basically you'd
maintain an internal variable reflecting the current row color, toggle the
row color via a click ("shift click" is not possible still). When you
take an action on the selected list, you then loop through the array and
act on ones with the selection color toggle on.
Its too bad that it is this way. Multiple selection is such a fundamental
user interaction on all platforms. The above work arounds do "work" but
they are minimalist. You could, after all, build functional user
interfaces without buttons.
The second is a technote from a Forte technote:
Technote #10684
Often times it is desirable to put FieldWidgets in OutlineFields to give
the user an ability to click on them as they would in other parts of the
window. However, because OutlineFields are built upon the DisplayNode
class, you cannot define a FieldWidget in the DisplayNode. You can
however define an ImageData attribute for the DisplayNode, and assign any
PictureGraphic to the ImageData attribute.
