|
|
jaccesswalker - navigate through the component trees in a particular
|
|
Java Virtual Machine and present the hierarchy in a tree view
|
|
.SH DESCRIPTION
|
|
.PP
|
|
You select a node in the tree, and from the \f[B]Panels\f[R] menu, you
|
|
select \f[B]Accessibility API Panel\f[R].
|
|
The \f[V]jaccesswalker\f[R] tool shows you the accessibility information
|
|
for the object in the window.
|
|
.SH RUNNING THE JACCESSWALKER TOOL
|
|
.PP
|
|
To use \f[V]jaccesswalker\f[R], launch the \f[V]jaccesswalker\f[R] tool
|
|
after launching a Java application.
|
|
For example, to launch \f[V]jaccesswalker\f[R], enter the following
|
|
command:
|
|
.PP
|
|
\f[B]Note:\f[R]
|
|
.PP
|
|
\f[V]JAVA_HOME\f[R] is an environment variable and should be set to the
|
|
path of the JDK or JRE, such as,
|
|
\f[V]c:\[rs]Program Files\[rs]Java\[rs]jdk-10\f[R].
|
|
.RS
|
|
.PP
|
|
\f[V]%JAVA_HOME%\[rs]bin\[rs]jaccesswalker.exe\f[R]
|
|
.RE
|
|
.PP
|
|
You now have two windows open: The Java application window, and the
|
|
window for the \f[V]jaccesswalker\f[R] tool.
|
|
There are two tasks that you can do with \f[V]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[V]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].
