Eclipse Plugin: Is there a way to get the External Tools Configurations Tree?
<p>Is there a way to get the orange-highlighted tree(see img) of the "External Tools Configurations..." window? </p>

<p>If not, which classes of the official Eclipse-API can I use to build my own TreeViewer? </p>

<p>This question <a href="https://stackoverflow.com/questions/39052708/eclipse-plugin-get-launch-configurations-tree-list-in-a-dialog">here: Eclipse Plugin - get Launch Configurations Tree List in a Dialog</a> is similar to mine. There, the official Eclipse-API classes were given. Another approach there would have been to use the <code>LaunchConfigurationFilteredTree</code> even if it is not official API. Is there a similiar class for the ExternalTools?</p>
