如何使用Scripting Bridge从脚本化应用程序调用命令？

Question

我正在开发一个应用程序，需要使用Scripting Bridge来处理Apple版本的MS-Word。我需要调用其 sdef 文件中定义的MS-Word命令，但我无法弄清楚如何操作。

sdef文件中命令的定义

<command name="reset" code="sTXTmFBr" description="Removes paragraph formatting that differs from the underlying style. For example, if you manually right align a paragraph and the underlying style has a different alignment, the reset method changes the alignment to match the style formatting.">
    <direct-parameter type="4046"/>
</command>

及其在头文件中的定义

@interface WordApplication : SBApplication
...
- (void) reset:(Word4046)x;  // Removes paragraph formatting that differs from the underlying style. For example, if you manually right align a paragraph and the underlying style has a different alignment, the reset method changes the alignment to match the style formatting.
...
@end

sdef文件中direct-parameter类型的定义：

<enumeration name="4046" code="4046">
    <enumerator name="paragraph" code="cpar"/>
    <enumerator name="paragraph format" code="w136"/>
</enumeration>

及其在头文件中的定义

enum Word4046 {
    Word4046Paragraph = 'cpar',
    Word4046ParagraphFormat = 'w136'
};
typedef enum Word4046 Word4046;

我要重置的对象类的定义：

<class name="paragraph format" code="w136" description="Represents all the formatting for a paragraph." inherits="base object" plural="paragraph formats">
...
</class>

及其在头文件中的定义

// Represents all the formatting for a paragraph.
@interface WordParagraphFormat : WordBaseObject
...
@end

我的应用编译且不崩溃的唯一方法是：

WordApplication *sbApplication; // SBObject which represents Word App
WordParagraphFormat *sbParagraph; // SBObject which represents a paragraph format
[sbApplication reset:Word4046ParagraphFormat]

但它显然什么也没做，因为我没有指定我要重置的对象，而是指定该对象的类型。

如何重置sbParagraph对象？

感谢。
