Name
jaccesswalker - navigate through the component trees in a particular Java Virtual Machine and present the hierarchy in a tree view
Description
You select a node in the tree, and from the Panels
menu, you select Accessibility API Panel. The
jaccesswalker tool shows you the accessibility information
for the object in the window.
Running the jaccesswalker Tool
To use jaccesswalker, launch the
jaccesswalker tool after launching a Java application. For
example, to launch jaccesswalker, enter 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\jaccesswalker.exe
You now have two windows open: The Java application window, and the
window for the jaccesswalker tool. There are two tasks that
you can do with jaccesswalker . You can build a tree view
of the Java applications' GUI hierarchy, and you can query the Java
Accessibility API information of a particular element in the GUI
hierarchy.
Building the GUI Hierarchy
From the File menu, select Refresh
Tree menu. The jaccesswalker 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.
Examining a GUI Component
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 Panels, and then Display Accessibility Information.
