Get Value

Retrieves the current value of a Java UI element using the Java Access Bridge.

Common Properties​

  • Name - The custom name of the node.
  • Color - The custom color of the node.
  • Delay Before (sec) - Waits in seconds before executing the node.
  • Delay After (sec) - Waits in seconds after executing node.
  • Continue On Error - Automation will continue regardless of any error. The default value is false.
info

If the ContinueOnError property is true, no error is caught when the project is executed, even if a Catch node is used.

Inputs​

  • Window Title - The title of the target window containing the Java application.
  • Window Handle - The handle (HWND) of the target window.
  • Full Path - The full path to the target element in the Java application's accessibility tree.

Options​

  • Wait Timeout (sec) - The maximum time (in seconds) to wait for the element to become available. Default is 5 seconds.

Output​

  • Value - The current value of the element.

How It Works​

The Get Value node interacts with Java applications through the Java Access Bridge to retrieve the current value of a UI element. When executed, the node:

  1. Waits for the specified Java context to become available based on the Window Title, Window Handle, and Full Path
  2. If the element is found, it retrieves the current value using GetCurrentAccessibleValueFromContext
  3. Returns the retrieved value as a string
  4. If the element is not found or value retrieval fails, appropriate errors are thrown

Requirements​

  • Java Access Bridge must be enabled in the target Java application
  • The target Java application must be running and accessible
  • Valid Window Title, Window Handle, and Full Path to the target element

Error Handling​

The node will return specific errors in the following cases:

  • Element not found within the specified timeout period
  • Context value could not be retrieved from the element
  • General error during value retrieval
  • General exceptions during execution

Usage Notes​

  • Ensure the Java Access Bridge is properly configured in your Java application
  • The Full Path should be obtained using Java accessibility tools or by inspecting the application's accessibility tree
  • The default timeout of 5 seconds can be adjusted based on application responsiveness
  • This node is particularly useful for retrieving values from input fields, sliders, and other elements that have a current value
  • The retrieved value can be used in subsequent nodes for processing or validation
