The base class for all UIA node properties.
TdxAutomationProperty = class(
TObject
)
UIA node properties define a control/UI element in the UI Automation tree.
The list below outlines key members of the TdxAutomationProperty class. These members allow you to manage an individual UIA node property.
CalculatedSpecifies if the UIA node property is calculated.ClearResets the UIA node property.IsNullIdentifies if the UIA node property is specified.
The TdxCalculateAutomationPropertyEvent procedural type references the currently processed UI node automation property as a TdxAutomationProperty object (AProperty).
Tip
Cast the AProperty parameter value to the corresponding terminal TdxAutomationProperty class descendant to access all public API members.
You can call the AProperty.ClassType function or use any other RTTI functionality to identify the actual UIA node property type.
Do not use the TdxAutomationProperty class directly. Use the TdxStringAutomationProperty class instead.
