Links between CPM controls Impact Reference Guide

• Destination control: The control’s property that receives the value when the link selection is "Set link
to here." For example, if you select "Set link to here" on an Indicator Light’s property, then link to a
Toggle Button’s property, the Indicator Light is the Destination.
• Ending control: The control that is selected to end the link process. When you create right-click links,
the beginning control normally keeps the focus when the link is complete. To shift the focus to the
Ending control when the link is complete, hold down the Ctrl key while you right-click on the Desti-
nation control.
Link Properties
All links are created and displayed on each control’s Properties, Methods, or Events tabs, and displayed on
the Link Summary tab. This example shows links on a control’s Properties tab.
Link Events and Methods
You can only link from one control’s event (source) to another control’s method (destination), but you can
create the link from either control.
If you create links from multiple events to one method, the events are processed in the order that they appear
in the method’s link display.
If you create links from one event to multiple methods, the methods are processed in the order that they
appear in the events’s link display.
Creating Drag and Drop Links in CPM
You can make multiple links between control properties, methods, and events. When the source changes, the
destination is updated based on the order in the outgoing links list.
