how to open jar selection dialog at the eclipse pulgin code

At开发者_JS百科 Project > Properties > Java Build Path > Libraries tab you click Add Jars button, you will see the JAR Selection dialog.

I like to open this JAR Selection dialog on my plugin code.

How to open this?

With the Eclipse RCP edition (which you must have since you are developing a plugin), you can use the Plugin Spy (Alt+Shift+F1) and see what exact class you need:

It is based on org.eclipse.jdt.internal.ui.viewsupport.FilteredElementTreeSelectionDialog (strangely absent from the sources of org.eclipse.jdt.internal.ui.viewsupport), derived from org.eclipse.ui.dialogs.ElementTreeSelectionDialog.

If you want to see how it is opened, you need to have a look to the global window opening that dialog:

It is the org.eclipse.jdt.internal.ui.preferences.BuildPathsPropertyPage, from which you can infer the various action classes associated with the button and see how it works.
