Create Method
Description

Returns an empty VisualRelationsCollection Object, which you can use to define the related objects for a test object's visual relation identifier.
Syntax

setVRIColl = VisualRelations.Create
Example

The following example demonstrates the use of a VisualRelations collection with a test object that has an ambiguous programmatic description. The same test object is used to represent different buttons in the calculator application based on the relative position of the buttons to the left and right of that button. Using these settings, the example below clicks on buttons 2, 5, and 8 in the calculator. (The example assumes that all objects from the calculator application have been added to the object repository.)

For i = 2 to 8 step 3

print ''Now selecting the object that matches button '' & i & '' via the related buttons '' & (i-1) & '' and '' & (i+1)

'Define an ambiguous button object on the calculator.

Set obj = Window(''text:=Calculator'').WinButton(''text:=.*'')

'Define two visual relations for the current button.
