Question

我正在改变插件的语言环境，正如我在此处提到的那样：http://jaider.net/12-06-2011/how-to-internationalize-your-eclipse-plug-in/ 但是有一些组件需要刷新（如果它们是可见的），例如自定义视图（org.eclipse.ui.views）或Menu，以避免重启Eclipse。我需要你的帮助。

Answer 1

该平台无法在运行时切换区域设置。 IExtensionRegistry在加载视图的扩展时选择了一个区域设置，更新它们的唯一一般方法是重新启动。

org.eclipse.core.runtime.IExtensionRegistry添加了新的多语言支持（可能在3.7.0？），但框架目前还没有使用它。

编辑：重启

要使用新的语言环境重新启动eclipse，您需要更改命令行（更新 -nl 标志），将其保存在系统属性eclipse.exitdata中，然后退出{{ 1}}与IApplication。有关如何使用此示例的示例，请参阅org.eclipse.equinox.app.IApplication.EXIT_RELAUNCH。

谢谢保罗。这里是用新语言重启的代码：

private static final String PROP_VM = "eclipse.vm"; //$NON-NLS-1$
private static final String PROP_VMARGS = "eclipse.vmargs"; //$NON-NLS-1$
private static final String PROP_COMMANDS = "eclipse.commands"; //$NON-NLS-1$
private static final String PROP_EXIT_CODE = "eclipse.exitcode"; //$NON-NLS-1$
private static final String PROP_EXIT_DATA = "eclipse.exitdata"; //$NON-NLS-1$
private static final String CMD_NL = "-nl"; //$NON-NLS-1$
private static final String CMD_VMARGS = "-vmargs"; //$NON-NLS-1$
private static final String NEW_LINE = "\n"; //$NON-NLS-1$

private static void restart(String nl) {
    String command_line = buildCommandLine(nl);
    if (command_line == null) {
        return;
    }
    System.setProperty(PROP_EXIT_CODE, org.eclipse.equinox.app.IApplication.EXIT_RELAUNCH.toString());//Integer.toString(24)
    System.setProperty(PROP_EXIT_DATA, command_line);
    Workbench.getInstance().restart();
}

private static String buildCommandLine(String nl) {
    String property = System.getProperty(PROP_VM);  

    StringBuffer result = new StringBuffer();
    if (property != null) {
        result.append(property);
    }
    result.append(NEW_LINE);

    // append the vmargs and commands. Assume that these already end in \n
    String vmargs = System.getProperty(PROP_VMARGS);
    if (vmargs != null) {
        result.append(vmargs);
    }

    // append the rest of the args, replacing or adding -data as required
    property = System.getProperty(PROP_COMMANDS);
    if (property != null) {// find the index of the arg to replace its value
        int cmd_nl_pos = property.lastIndexOf(CMD_NL);
        if (cmd_nl_pos != -1) {
            cmd_nl_pos += CMD_NL.length() + 1;
            result.append(property.substring(0, cmd_nl_pos));
            result.append(nl);
            result.append(property.substring(property.indexOf('\n',
                    cmd_nl_pos)));
        } else {
            result.append(NEW_LINE);
            result.append(property);
            result.append(NEW_LINE);
            result.append(CMD_NL);
            result.append(NEW_LINE);
            result.append(nl);
        }
    }

    // put the vmargs back at the very end (the eclipse.commands property
    // already contains the -vm arg)
    if (vmargs != null) {
        result.append(CMD_VMARGS);
        result.append(NEW_LINE);
        result.append(vmargs);
    }


    return result.toString();
}
