无法扩展帮助菜单

eclipse-pde eclipse-rcp eclipse-plugin eclipse

我想从eclipse插件中添加 Request Support 按钮到 Help 菜单。

我先从一个 *.e4xmi 现在我试着从 plugin.xml 但仍然无法使按钮出现在 帮助 菜单。

我在 Eclipse Spy Plug-in .
内容 plugin.xml文件 以下内容:

<extension
    point="org.eclipse.ui.menus">
    <menuContribution
        allPopups="false" (tried with true and same result)
        locationURI="menu:help?after=about">
        <menu
            commandId="com.plugin.RequestSupport"
            id="requestSupport"
            label="Request Support">
        </menu>
    </menuContribution>
</extension>
<extension
    point="org.eclipse.ui.commands">
    <command
        defaultHandler="com.plugin.handlers.RequestSupportHandler"
        description="Opens up default e-mail client with preset basic informations"
        id="com.plugin.RequestSupport"
        name="Request Support">
    </command>
</extension>

我错过了什么?

从格雷格的回答中得到的解决方案:

<extension
    point="org.eclipse.ui.menus">
    <menuContribution
        allPopups="false" (tried with true and same result)
        locationURI="menu:help?after=about">

<menu commandId="com.plugin.RequestSupport" id="requestSupport" label="Request Support"> </menu>

<command commandId="com.plugin.RequestSupport" id="requestSupport" label="Request Support" style="push"> </command> </menuContribution> </extension>

这就是“检查更新”的用途:

<extension
     point="org.eclipse.ui.menus">
  <menuContribution
        locationURI="menu:help?after=additions">
        <command
              commandId="org.eclipse.equinox.p2.ui.sdk.update"
              mnemonic="%Update.command.mnemonic"
              id="org.eclipse.equinox.p2.ui.sdk.update"
              icon="icons/obj/iu_update_obj.png">
        </command>

在“添加”位置后添加的。

创建帮助菜单的代码定义了许多位置:

private MenuManager createHelpMenu() {
    MenuManager menu = new MenuManager(IDEWorkbenchMessages.Workbench_help, IWorkbenchActionConstants.M_HELP);
    addSeparatorOrGroupMarker(menu, "group.intro"); //$NON-NLS-1$
    // See if a welcome or intro page is specified
    if (introAction != null) {
        menu.add(introAction);
    } else if (quickStartAction != null) {
        menu.add(quickStartAction);
    }
    menu.add(new GroupMarker("group.intro.ext")); //$NON-NLS-1$
    addSeparatorOrGroupMarker(menu, "group.main"); //$NON-NLS-1$
    menu.add(helpContentsAction);
    menu.add(helpSearchAction);
    menu.add(dynamicHelpAction);
    addSeparatorOrGroupMarker(menu, "group.assist"); //$NON-NLS-1$
    // See if a tips and tricks page is specified
    if (tipsAndTricksAction != null) {
        menu.add(tipsAndTricksAction);
    }
    // HELP_START should really be the first item, but it was after
    // quickStartAction and tipsAndTricksAction in 2.1.
    menu.add(new GroupMarker(IWorkbenchActionConstants.HELP_START));
    menu.add(new GroupMarker("group.main.ext")); //$NON-NLS-1$
    addSeparatorOrGroupMarker(menu, "group.tutorials"); //$NON-NLS-1$
    addSeparatorOrGroupMarker(menu, "group.tools"); //$NON-NLS-1$
    addSeparatorOrGroupMarker(menu, "group.updates"); //$NON-NLS-1$
    menu.add(new GroupMarker(IWorkbenchActionConstants.HELP_END));
    addSeparatorOrGroupMarker(menu, IWorkbenchActionConstants.MB_ADDITIONS);
    // about should always be at the bottom
    menu.add(new Separator("group.about")); //$NON-NLS-1$

    ActionContributionItem aboutItem = new ActionContributionItem(aboutAction);
    aboutItem.setVisible(!Util.isMac());
    menu.add(aboutItem);
    menu.add(new GroupMarker("group.about.ext")); //$NON-NLS-1$
    return menu;
}

(来自 org.eclipse.ui.internal.ide.WorkbenchActionBuilder )

所有的 addSeparatorOrGroupMarker ,请 new Separator 和 new GroupMaker 调用定义可以在之后添加的ID。
