The \f[CB]jaccesswalker\f[R] tool shows you the accessibility information for the object in the window. .SH RUNNING THE JACCESSWALKER TOOL .PP To use \f[CB]jaccesswalker\f[R], launch the \f[CB]jaccesswalker\f[R] tool after launching a Java application. For example, to launch \f[CB]jaccesswalker\f[R], enter the following command: .PP \f[B]Note:\f[R] .PP \f[CB]JAVA_HOME\f[R] is an environment variable and should be set to the path of the JDK or JRE, such as, \f[CB]c:\\Program\ Files\\Java\\jdk\-10\f[R]. .RS .PP \f[CB]%JAVA_HOME%\\bin\\jaccesswalker.exe\f[R] .RE .PP You now have two windows open: The Java application window, and the window for the \f[CB]jaccesswalker\f[R] tool. There are two tasks that you can do with \f[CB]jaccesswalker\f[R] . You can build a tree view of the Java applications\[aq] GUI hierarchy, and you can query the Java Accessibility API information of a particular element in the GUI hierarchy. .SH BUILDING THE GUI HIERARCHY .PP From the \f[B]File\f[R] menu, select \f[B]Refresh Tree\f[R] menu. The \f[CB]jaccesswalker\f[R] tool builds a list of the top\-level windows belonging to Java applications. The tool then recursively queries the elements in those windows, and builds a tree of all of the GUI components in all of the Java applications in all of the JVMs running in the system. .SH EXAMINING A GUI COMPONENT .PP After a GUI tree is built, you can view detailed accessibility information about an individual GUI component by selecting it in the tree, then selecting \f[B]Panels\f[R], and then \f[B]Display Accessibility Information\f[R].
