how to set or replace a file on project explorer on gnu arm eclipse or cdt?

Question

I'm studying eclipse cdt plug-in development use gnuarmeclipse.

previous question.

I need to set or replace a file(such a linkerscript) in project explorer.

I know it change on project properties -> C/C++ Build -> Settings -> Tool Settings -> GCC C Linker -> General -> Script file(-T).

But I want, it execute on project explorer context menu.

See below.

1) Select LD(folder for only one linkerscript file) on Project Explorer.

2) Right click and select "Set Linker Script File" on context menu.

3) Select a file to set or replace on Open window.

This is setlinkerscript.java

public class setlinkerscript extends AbstractHandler {

public Object execute(ExecutionEvent event) throws ExecutionException {
    // TODO Auto-generated method stub

    IWorkbenchWindow window = HandlerUtil.getActiveWorkbenchWindowChecked(event);

    Shell shell = new Shell();
    FileDialog dialog = new FileDialog(shell, SWT.OPEN);
    dialog.setFilterExtensions(new String[] {"*.x"});
    String linkerscript = dialog.open();
    System.out.println(linkerscript);

    return null;
}}

I got a file location but I don't know where I set on eclipse.

Any API or method is there? or recommend documents.

I can't attach jpg for figure.. need more reputation point. Sorry!

Thanks in advance.

public class setlinkerscript extends AbstractHandler {

    public Object execute(ExecutionEvent event) throws ExecutionException {
        // TODO Auto-generated method stub

        IWorkbenchWindow window = HandlerUtil.getActiveWorkbenchWindowChecked(event);

        Shell shell = new Shell();
        FileDialog dialog = new FileDialog(shell, SWT.OPEN);
        dialog.setFilterExtensions(new String[] {"*.x"});       
        String linkerscript = dialog.open();    // get new linkerscript with path       

        IEditorPart  editorPart = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().getActiveEditor();
        String activeProjectName = null;

        if(editorPart  != null)
        {
            IFileEditorInput input = (FileEditorInput)editorPart.getEditorInput();
            IFile file = input.getFile();
            IProject activeProject = file.getProject();
            activeProjectName = activeProject.getName();
        }

        // ===========================================================================================================
        // CProject

        ICProject cproject = CoreModel.getDefault().getCModel().getCProject(activeProjectName);
        IManagedBuildInfo buildInfo = ManagedBuildManager.getBuildInfo(cproject.getResource());

        // ===========================================================================================================
        // config

        IConfiguration configs[] = buildInfo.getManagedProject().getConfigurations();

        int i;
        for(i=0; i<2; i++)
        {
            // configs[0] : Debug
            ITool[] tool = configs[i].getTools();

            // configs[1] : Release

            // ===========================================================================================================
            // tool

            // tool[3] : EISC GCC C Linker
            IOption[] option = tool[3].getOptions();

            // option[0] : linkerscript
            Object value = option[0].getValue();

            try {
                option[0].setValue(linkerscript);
            } catch (BuildException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }

        // ===========================================================================================================

        return null;
    }
