<br>主题：怎样调用全局的枚举变量？!
<br>内容：怎样调用全局的枚举变量？<BR>又一个单文档程序，我在应用程序类CMyDrawApp的文件MyDraw.cpp中定义了如下变量;<BR>enum SelectMode<BR>{<BR>&nbsp;&nbsp;&nbsp;&nbsp;none,<BR>&nbsp;&nbsp;&nbsp;&nbsp;netSelect,&nbsp;&nbsp;&nbsp;&nbsp;//框选<BR>&nbsp;&nbsp;&nbsp;&nbsp;move,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;//移动<BR>&nbsp;&nbsp;&nbsp;&nbsp;size&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;//缩放<BR>};<BR>SelectMode selectMode = none;<BR>然后我想在视图类CMyDrawView的文件MyDrawView.cpp中做如下使用：<BR>if (selectMode == size)<BR>{....}<BR>该怎样在MyDrawView.cpp中如何声明？谢谢<BR>[e-mail]<BR>qq:56700320

<br>内容：你可以这样：<BR>把枚举类型SelectMode 的定义放在一个头文件中，<BR>如selmode.h:<BR>enum SelectMode<BR>{<BR>&nbsp;&nbsp;&nbsp;&nbsp;none,<BR>&nbsp;&nbsp;&nbsp;&nbsp;netSelect,&nbsp;&nbsp;&nbsp;&nbsp;//框选<BR>&nbsp;&nbsp;&nbsp;&nbsp;move,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;//移动<BR>&nbsp;&nbsp;&nbsp;&nbsp;size&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;//缩放<BR>};<BR><BR>MyDraw.cpp:<BR>#include &#34;selmode.h&#34;<BR>SelectMode selectMode = none;<BR><BR>MyDrawView.cpp:<BR>#include &#34;selmode.h&#34;<BR>extern SelectMode selectMode;<BR><BR>if (selectMode == size)<BR>{....}<BR>
