Application Event Trigger

UiPath.UIAutomationNext.Activities.NNativeEventTrigger

Description

Sets up a trigger based on a native event of any type of element (top-level window or any other indicated UI element). You can indicate the target element on screen and then choose the native event from the list of events supported by that element.

This activity is compatible with Object Repository.

The trigger must be the first activity in the workflow and the workflow is triggered when a certain UI event occurs. Only one trigger per workflow is allowed. For more details, check out Trigger-based Attended Automation.

Note:

If you are using a Studio version lower than 2023.4, you need to place the Application Event Trigger activity inside a Trigger Scope activity. In this case, the Application Event Trigger activity does not display the Scheduling mode and Enabled properties and the Scheduling mode property is available in the Trigger Scope activity.

Windows - Legacy, Windows configuration

Designer panel

• Click Indicate target on screen to indicate the UI element to use as target.

  After you indicate the target, select the Menu button to access the following options:

  • Indicate target on screen - Indicate the target again.
  • Edit target - Open the selection mode to configure the target.
  • Remove informative screenshot - Remove the screenshot of the target application or web page.
  • Add to Object Repository - Add the current UI element to a library project, from where it can be reused throughout your automation process.

• Event type - The list of native event types specific to the indicated element. The event type must be set. The exposed events list is dependent on the target element type and on the target application technology. For example, a web UI element might expose a different list of events than a Java UI element.

Properties panel

Common

• Display name - The name displayed for the activity in the Designer panel. A display name is automatically generated when you indicate a target.

Input

• Match sync - Indicates whether the matching of the target element selector is done synchronously or asynchronously. It is supported only for Java events except for Appeared and Disappeared. This field supports only Boolean values. The default value is False.
• Selectors - Optional collection of selectors to monitor for the indicated event; these selectors are monitored alongside the indicated target. The selectors must be full (not partial) selectors.

• Target - The target element: top-level window or UI element. Only strict selectors are supported, without anchors. Target element must be set. Before indicating on screen, this field is set to (null). Once the target is indicated, all properties regarding the element that was indicated are displayed.
  • Strict selector - The strict selector generated for the target UI element. It is empty for top-level windows.
  • Window selector (Application instance) - The selector for the application window (application/browser).

Misc

• Enabled - If set to False, the trigger starts but does not fire any events. It can be enabled later at runtime, by using the Enable Local Trigger activity. This property is hidden when the Application Event Trigger activity is placed inside a Trigger Scope. This field supports only Boolean values. The default value is True.
• Private - If selected, the values of variables and arguments are no longer logged at Verbose level. This field supports only Boolean (True, False) values. The default value is False.

Options

• Include children - When selected, the children of the specified UI element are also monitored. It supports all event types except for Appeared or Disappeared and any UI element except for top-level windows. This field supports only Boolean (True, False) values. The default value is False.
• Scheduling mode - It specifies how to execute the actions when a trigger is fired. Choose one of five options from the drop-down menu:
  • Sequential - Actions are executed one after another.
  • Concurrent - Actions execution can overlap.
  • OneTime - Executes one action and exits monitoring.
  • Sequential Collapse - Ignores all upcoming events, except the latest, until the current event finishes execution.
  • Sequential Drop - Stops the previous event execution and starts the next event.

  For Sequential and Concurrent modes the monitoring continues until either the user stops the execution or a Break activity is met.

Native events

About

The native events monitoring mechanism has been improved by implementing new sets of events supported by different types of application technologies:

• WND native events
• CTRL native events

HTML events - UI elements

Note: The following event types are only supported for web applications identified by <html> selectors that have only the app attribute:

• Download state changed
• Tab activated
• Tab created
• Tab removed
• Tab updated

For now, these events are allowed only when the Window selector contains the <html> part, such as: <html app='chrome.exe' />. Other attributes such as title or url are not allowed. If the Window selector contains attributes other than app, a runtime error is generated.

Strict selector should be empty.

These event types are not supported for embedded browsers.

Inheritance: TriggerArgs > UiElementTriggerArgs > NativeTriggerBaseArgs > WebRequestBaseArgs > WebRequestErrorOccurredArgs

Property	Type	Description
Error	String	The error description.
FromCache	Boolean	Indicates if this response was fetched from disk cache.
Ip	String	The server IP address that the request was actually sent to.

WebRequestResponseStartedArgs

Returns data from the following events for HTML:

• Web request: Response started

Inheritance: TriggerArgs > UiElementTriggerArgs > NativeTriggerBaseArgs > WebRequestBaseArgs → WebRequestHeadersReceivedArgs→ WebResponseCacheDetailsArgs→ WebRequestResponseStartedArgs

WebRequestSendHeadersArgs

Returns data from the following events for HTML:

• Web request: Send HTTP headers

Inheritance: TriggerArgs > UiElementTriggerArgs > NativeTriggerBaseArgs > WebRequestBaseArgs > WebRequestSendHeadersArgs

Property	Type	Description

UiaToggledArgs

Returns data from the following events for UIA:

• Toggled events

Inheritance: TriggerArgs > UiElementTriggerArgs > NativeTriggerBaseArgs > UiaToggledArgs

Property	Type	Description
State	String	The new state for the target element.

UiaTextSelectionChangedArgs

Returns data from the following events for UIA:

• Text selection changed events

Inheritance: TriggerArgs > UiElementTriggerArgs > NativeTriggerBaseArgs > UiaTextSelectionChangedArgs

Property	Type	Description
TextRanges	UiaTextRange()	Array that holds different information about the selected text elements in the target element (we can have multiple selected text elements in case non-adjacent text selection). Each item from this array exposes the following information: Text (type String) - Text selection for that selected text element. Example: TriggerEventArgs.TextRanges(0).Text represents the text of the first selected text element. BoundingRectangles (type Rectangle()) - Array of bounding rectangles for the selected text element. A selected text element can have multiple bounding rectangles associated with it if it spans multiple lines. Each bounding rectangle is of type Rectangle {X, Y, Width, Height} and it provides information about the position and size of the element. Example: TriggerEventArgs.TextRanges(0).BoundingRectangles(0) represents the bounding rectangle of the first line in the first selected text element.

Event Inspection Tool

In the context of trigger-based attended automation, the Event Inspection Tool can be used to identify the type of native events triggered when you interact with certain UI elements in an application, and then it can be used for configuring the Application Event Trigger activity. The tool captures and monitors all the selected event types, such as Click, Key pressed, Focus gained, Focus lost, and other relevant interactions, enabling you to analyze the actions performed and, if applicable, diagnose issues.

The Event Inspection Tool can be opened from the UI Explorer, once a valid UI element is selected, by clicking the Inspect Events toolbar button.

The toolbar consists of the following options:

• Record - The events generated by interacting with the UI element are recorded and added to the events list.
• Pause - The events generated by the UI element when you interact with it are no longer recorded.
• Highlight - Shows the contour of the target element and brings it to the foreground for a few seconds. The highlight stays on until it is disabled.
• Open in UI Explorer - The monitored element is opened in UI Explorer where you can observe the selector of that element.

Once you start event recording, two more options become available:

• Clear - Deletes all the recorded events.
• CSV - The captured events can be exported to a .csv file for further analysis.

The Event Inspection Tool window has two main sections:

• Event filter - Allows selecting the types of events you want to monitor for the target element.
• Event list - Displays information about captured events.

You can filter event types to be captured by enabling or disabling the checkboxes from the list of event types. The list may vary based on the selected element technology.

All mouse event types (Mouse move, Mouse pressed, Mouse released, Mouse entered, Mouse exited), specific for Web or Java UI elements, are disabled by default because the event list, in such cases, can become quite large. Our recommendation is to enable the mouse event types only if you have a specific need to monitor them.

It is worth also mentioning that event types can be enabled or disabled even after you started the event recording.

The event list has three columns:

• Event Name - The event type.
• Time Stamp - The date and hour when the event was performed.
• Event Data - The associated data and parameters for a certain event.

Each column can be sorted in ascending or descending order. The events are displayed by default in the order they were performed.

When the Disappeared event type is found, you can no longer continue monitoring and an error message is displayed on the screen. When clicking any option from the toolbar, the same error message is displayed on the screen. The only available options are to either clear the data or export it to a .csv file. To start monitoring again, close the window and open another instance of the Event Inspection Tool.
