Guide Section: Processing Events and Performing Actions | EASAP Tree: EVENT PROCESSING→EVENT

When one of several visible data entry objects change, VALUE CHANGED creates a reference to the changed object and then triggers an EVENT.

One or more objects are listed in Objects: and if one of them changes: the Event Source: references the object that has changed and an subsequent EVENT is triggered with corresponding ACTION's.

If no objects are specified, VALUE CHANGED will behave globally: if any value in the EASAP changes, the ACTION's associated with the VALUE CHANGED EVENT will take place.

Value Changed
Optional Parameters:
Objects:	Select one or more visible data entry objects. If left empty, it will be triggered by the change of any value in the EASAP.
Event Source:	A reference to the object whose value has changed.

To trigger SET STYLE ACTION from a VALUE CHANGED EVENT:

• Right-click USER INTERFACE
  • Select Child→Add USER INTERFACE STYLE LIST
• Right-click USER INTERFACE STYLE LIST
  • Select Child→Add USER INTERFACE STYLES
• Right-click USER INTERFACE STYLES
  • Select Child→Add USER INTERFACE STYLE
• Right-click user_interface_style1,
  • Select Child→Add BACKGROUND
    • Set Color: 'blue'
• Right-click BACKGROUND,
  • Select Sibling→Add TEXT STYLE
    • Set Color: 'red'

• Create two or more data entry objects: input1, input2, …
• Add an EVENT PROCESSING
• Right-click the EVENT branch,
  • Select Child→Add VALUE CHANGED
    • Set Objects: input1,input2,…
    • Set Event Source: changedBox
  • Right-click the ACTION branch,
    • Select Child→Add SET STYLE ACTION
      • Set Object: changedBox

changedBox's value is the particular input that changed.

The name changedBox is declared in Event Source: above.

So now in our example: if input2 changes, only its USER INTERFACE STYLE will be updated: in this case red text on a blue background.
