JACCESSINSPECTOR(1)

NAME

jaccessinspector - examine accessible information about the objects in the Java Virtual Machine using the Java Accessibility Utilities API

DESCRIPTION

The jaccessinspector tool lets you select different methods for examining the object accessibility information:

•   When events occur such as a change of focus, mouse movement, property change, menu selection, and the display of a popup menu

•   When you press the F1 key when the mouse is over an object, or F2 when the mouse is over a window

After an object has been selected for examination, the jaccessinspector tool displays the results of calling Java Accessibility API methods on that object.

RUNNING THE JACCESSINSPECTOR TOOL

To use the jaccessinspector tool, launch the jaccessinspector tool after launching a Java application. To launch jaccessinspector, run the following command:

Note:

JAVA_HOME is an environment variable and should be set to the path of the JDK or JRE, such as c:\Program Files\Java\jdk-10.

    %JAVA_HOME%\bin\jaccessinspector.exe

You now have two windows open: The Java application window and the jaccessinspector window. The jaccessinspector window contains five menus:

•   File Menu

•   UpdateSettings Menu

•   JavaEvents Menu

•   AccessibilityEvents Menu

•   Options Menu

The items in UpdateSettings, JavaEvents, and AccessibilityEvents menus let you query Java applications in a variety of ways.

FILE MENU

This section describes the File menu items.

AccessBridge DLL Loaded
    Enables and disables AccessBridge DLL Loaded.

Exit
    Exits from the tool.

UPDATESETTINGS MENU

This section describes the UpdateSettings menu items.

Update from Mouse
    Determines the x- and y-coordinates of the mouse (assuming the jaccessinspector tool window is topmost) when the mouse has stopped moving, and then queries the Java application for the accessible object underneath the mouse, dumping the output into the jaccessinspector window.

Update with F2 (Mouse HWND)
    Determines the x- and y-coordinates of the mouse (assuming the jaccessinspector tool window is topmost), and then queries the Java application for the accessible object of the HWND underneath the mouse, dumping the output into the jaccessinspector window.

Update with F1 (Mouse Point)
    Determines the x- and y-coordinates of the mouse (assuming the jaccessinspector tool window is topmost), and then queries the Java application for the accessible object underneath the cursor, dumping the output into the jaccessinspector window.

JAVAEVENTS MENU

This section describes the JavaEvents menu items.

Track Mouse Events
    Registers with the Java application all Java Mouse Entered events, and upon receiving one, queries the object that was entered by the cursor and dumps the output into the jaccessinspector window.

    Note: If the mouse is moved quickly, then there may be some delay before the displayed information is updated.

Track Focus Events
    Registers with the Java application all Java Focus Gained events, and upon receiving an event, queries the object that received the focus and dumps the output into the jaccessinspector window.

Track Caret Events
    Register with the Java application all Java Caret Update events, and upon receiving an event, queries the object in which the caret was updated, and dumps the output into the jaccessinspector window.

    Note: Because objects that contain carets are almost by definition objects that are rich text objects, this won't seem as responsive as the other event tracking options. In real use, one would make fewer accessibility calls in Caret Update situations (for example, just get the new letter, word, sentence at the caret location), which would be significantly faster.

Track Menu Selected | Deselected | Cancelled Events
    Registers with the Java application all Menu events, and upon receiving an event, queries the object in which the caret was updated, and dumps the output into the jaccessinspector window.

Track Popup Visible | Invisible | Cancelled Events
    Registers with the Java application all Popup Menu events, and upon receiving an event, queries the object in which the caret was updated, and dumps the output into the jaccessinspector window.

Track Shutdown Events
    Registers with the Java application to receive a Property Changed event when a Java application terminates.

ACCESSIBILITYEVENTS MENU

This section describes the AccessibilityEvents menu items.

Note: The items listed in the AccessibilityEvents menu are the most important for testing applications, especially for assistive technology applications.

Track Name Property Events
    Registers with the Java application all Java Property Changed events specifically on accessible objects in which the Name property has changed, and upon receiving an event, dumps the output into the scrolling window, along with information about the property that changed.

Track Description Property Events
    Register with the Java application for all Java Property Changed events specifically on accessible objects in which the Description property has changed, and upon receiving an event, dumps the output into the jaccessinspector window, along with information about the property that changed.

Track State Property Events
    Register with the Java application all Java Property Changed events specifically on accessible objects in which the State property has changed, and upon receiving an event, dumps the output into the jaccessinspector window, along with information about the property that changed.

Track Value Property Events
    Register with the Java application all Java Property Changed events specifically on accessible objects in which the Value property has changed, and upon receiving an event, dumps the output into the scrolling window, along with information about the property that changed.

Track Selection Property Events
    Register with the Java application all Java Property Changed events specifically on accessible objects in which the Selection property has changed, and upon receiving an event, dumps the output into the jaccessinspector window, along with information about the property that changed.

Track Text Property Events
    Register with the Java application all Java Property Changed events specifically on accessible objects in which the Text property has changed, and upon receiving one event, dump the output into the jaccessinspector window, along with information about the property that changed.

Track Caret Property Events
    Register with the Java application all Java Property Changed events specifically on accessible objects in which the Caret property has changed, and upon receiving an event, dumps the output into the jaccessinspector window, along with information about the property that changed.

Track VisibleData Property Events
    Register with the Java application all Java Property Changed events specifically on accessible objects in which the VisibleData property has changed, and upon receiving an event, dumps the output into the jaccessinspector window, along with information about the property that changed.

Track Child Property Events
    Register with the Java application all Java Property Changed events specifically on accessible objects in which the Child property has changed, and upon receiving an event, dumps the output into the jaccessinspector window, along with information about the property that changed.

Track Active Descendent Property Events
    Register with the Java application all Java Property Changed events specifically on accessible objects in which the Active Descendent property has changed, and upon receiving an event, dumps the output into the jaccessinspector window, along with information about the property that changed.

Track Table Model Change Property Events
    Register with the Java application all Property Changed events specifically on accessible objects in which the Table Model Change property has changed, and upon receiving an event, dumps the output into the jaccessinspector window, along with information about the property that changed.

This section describes the Options menu items.

Monitor the same events as JAWS
    Enables monitoring of only the events also monitored by JAWS.

Monitor All Events
    Enables monitoring of all events in the jaccessinspector window.

Reset All Events
    Resets the selected Options to the default settings.
