I want to display only Editors under General in preference page.
How would I do this?

My way to do that (only showing some of the Contributed Preference
Pages) was implementing a handler that opens a preference dialog that
only shows the IDs of the preference pages I want
Opening the dialog yourself you can by providing a String[] instance to
control which preference pages are shown.

public Object execute(ExecutionEvent event) throws ExecutionException {
IWorkbenchWindow window =
HandlerUtil.getActiveWorkbenchWindowChecked(event);

PreferenceDialog dialog = PreferencesUtil.createPreferenceDialogOn(
window.getShell(), null, getValidPreferenceIDs(), null);

dialog.open();

return null;
}

May be there is a better solution... though this one worked for me just
fine.

extend an abstract Handler ... and implement the method as seen above..

example for getting the String array:
/**
* remove the unwanted preferences..
*/
private static String[] getValidPreferenceIDs() {
List<String> validIds = new ArrayList<String>();
IConfigurationElement[] ce=
Platform.getExtensionRegistry().getConfigurationElementsFor( "org.eclipse.ui.preferencePages");
for (IConfigurationElement cele:ce) {
String s= cele.getAttribute("id");
validIds.add(s);
}
validIds.remove("org.eclipse.help.ui.browsersPreferencePage ");
validIds.remove("org.eclipse.help.ui.contentPreferencePage");

validIds.remove(" org.eclipse.update.internal.ui.preferences.MainPreferencePag e ");

return validIds.toArray(new String[0]);
}

Define a command in the plugin.xml. Ans use this handler as a default
handler.

Now you can either add the command to some menu or programmtically call it.

As I am very new to plugin development, I am not able to understand the
solution.
Could you please explain more, or please tell step by steps.

Anand,

You'll really need to take some more initiative and go learn the
background information.
