Eclipseのメニューバーやポップアップメニューは org.eclipse.ui.menus 拡張ポイントで制御することができますが、ある条件下でのみポップアップメニューを表示するとかの表示制御は下記のように、visibleWhen タグで行うことができます。
<extension point="org.eclipse.ui.menus">
<menuContribution locationURI="popup:org.eclipse.ui.popup.any">
<menu id="nu.mine.kino.plugin.newaction.menus.sampleMenu"
label="トップのメニュー">
<command commandId="nu.mine.kino.plugin.samples.rcp.command"
style="push">
</command>
<command
commandId="nu.mine.kino.plugin.newaction.commands.sampleCommand"
style="push">
</command>
<visibleWhen>
<with variable="activeMenuSelection">
<iterate ifEmpty="false"> <-ifEmptyは、Selectionがなかった時の判定。
<adapt type="org.eclipse.jdt.core.IJavaElement">
</adapt>
</iterate>
</with>
</visibleWhen>
</menu>
</menuContribution>
</extension>
このようにmenuやcommandに対して
<visibleWhen>
<with variable="activeMenuSelection">
<iterate ifEmpty="false">
<adapt type="org.eclipse.jdt.core.IJavaElement">
</adapt>
</iterate>
</with>
</visibleWhen>
という条件を設定できるって事ですね。

この変数に設定できる項目は org.eclipse.ui.ISources に定義されているようです。
package org.eclipse.ui;

import org.eclipse.ui.part.IShowInSource;
public interface ISources {
public static final String ACTIVE_CONTEXT_NAME = "activeContexts";

これらが全て、この箇所の変数として有効なのかはまだよく分かりませんが。。
