Examples (Using Pick Packets)

The following examples show how a pick packet can be either defined directly to an event packet (edgPacket) or defined as a method against an object or form to be applied to an event packet within a utility.

Applied to an Event Packet

The Applied to an Event Packet example shows how a standard pick packet can be defined while defining an event packet.

-- Define event packet

!packet = object EDGPACKET()

-- Set Members

!packet.description = 'Test Packet'

!packet.key = 'testPacket'

!packet.priority = 1

-- Defines action on completion of the pick

!packet.action ='!action(!this.return[1])'

-- Define pick sequence

!packet.pickPacket.stdElement('Pick Element')

-- Add event packet to the system

!!edgCntrl.add(!packet)

The pick packet definition can be either done using a standard method on the object (as above) or defined fully, where there is no standard method.

Method Definition

The Method Definition example is where an object/form has a method(s) that defines a pick packet sequence that can be applied to a standard event packet within the object/form.

The following is the definition of the method that defines the pick packet:

Method Definition

-- Define Method

define method .elementMove() is EDGPICKPACKET

-- Define pick packet

!pickPacket = object EDGPICKPACKET()

-- Define information

!pickPacket.key = 'element-position'

!pickPacket.description = 'Pick an element then a positions'

-- Define primary prompt

!pickPacket.prompt = 'Move element'

-- Declare first pick (element)

!pickPacket.picks[1] = object EDGPICKTYPE()

!pickPacket.picks[1].stdElement('(Pick element to move)')

-- Declare second pick (position)

!pickPacket.picks[2] = object EDGPICKTYPE()

!pickPacket.picks[2].stdPosition('(New position)')

-- Return

return !pickPacket

-- End method definition

endmethod

The following is an extract on how the above method would be used within the owning object/form:

-- Define Packet

!packet = object EDGPACKET()

.

.

.

-- Test for method

if(!option eq 'MOVE") then

!packet.pickPacket = !this.elementMove()

else

!packet.pickPacket = !this.elementBY()

endif

-- Add event to the system

!!edgCntrl.add(!packet)
