d_techFileId

Handle representing a techfile object.

t_fieldPrompt

Prompt string that appears in this field. To reference it, use:

formHandle->hiLayerField->prompt

t_callback

Callback string for this field. If a callback is specified, the value of the item selected is appended to this callback before being executed by SKILL.

The value of this field is always a list representing a layer icon. This value can be referenced by:

form->hiLayerField->value

The value is always a list containing the icon representation of the layer followed by a string representation. For example:

(50331991 106 26 "device (drawing1)")

The first three elements in this list represent the cyclic icon; the fourth element is the layer’s name followed by its purpose in parentheses.

l_layers

List containing the layers that should be displayed as possible choices for this field. Each layer is represented as a list of two strings—layer name and layer purpose.

For example:

list( list("device" "drawing1")
list("y0" "drawing")
list("y1" "drawing")
list("y2" "drawing") )

The layers specified must be defined in  d_techFileId. If nil is specified, all layers in  d_techFileId is displayed.

l_LPpair

An optional argument specifying the initial value of this layer field. This argument is a list containing the layer name (or number) and purpose. This layer must exist in  d_techFileId. If not specified, the first layer in the list l_layers becomes the initial value.

s_fieldName

Handle to the field. If you do not specify this argument, the default name is ’hiLayerField.

To reference the field after the form is created, use:

formHandle -> hiFieldSym

r_fieldHandle

Handle to the field.
