Parent Property
Description
Returns a reference to the superordinate object.
Objects within the VBS object model are accessed by hierarchy. You may descend in the
picture
hierarchy using Screen and Screenitems. You may ascend in the picture hierarchy by
using the Parent property.
Usage
The Parent property can be used as often as required within an object hierarchy. The following
section provides a systematic description of how to access all the elements in a hierarchy:
The Command
MsgBox MyCircle.Parent.Objectname
VBS for Creating Procedures and Actions
1.14 VBS Reference
MDM - WinCC: Scripting (VBS, ANSI-C, VBA)
System Manual, 11/2008,
471
returns the name of "Picture2" located one layer higher in the object hierarchy than the original
ScreenItem object "Circle1".
For example, if you wish to use "Parent" three times, ascend in the object hierarchy by three
layers:
MsgBox MyCircle.Parent.Parent.Parent.Objectname
returns the name of Picture1.
Reasoning:
● Original reference is to ScreenItem "Circle1"
● "Circle1" is within "Picture2" (Layer 1)
● "Picture2" is within Picture Window2 "BF2" (Layer 2)
● "BF2" is within "Picture 1"(Layer 3)
Example:
In the following example, the object name of the Parent object is displayed:
'VBS120
Dim objCircle
Set objCircle = HMIRuntime.Screens("ScreenWindow1").ScreenItems("Circle1")
MsgBox objCircle.Parent.ObjectName
