ArcEngine怪问题

<P>各位大侠，有没有碰见这种情况，ILegendItem不管怎么设置其标注属性，就是不起作用，也就是我不管怎么LabelSymbol的字体、大小、颜色设置，就是不起作用，画出来的字体一样都是黑色的，大小也一样。下面是关键代码，请帮我找错。</P>
<P> //clear the all legenditems<BR> ipLegend->ClearItems();</P>

<P> ipLegend->Refresh();</P><img src="images/post/smile/dvbbs/em30.gif" />

楼主搞深下去了，帮顶一下<img src="images/post/smile/dvbbs/em01.gif" />

<P>郁闷!没有人再回答.</P><img src="images/post/smile/dvbbs/em15.gif" />

<P>最关键的是我要改变字体的颜色，我设置Legend TitleSymbol是成功的，但就是ILegendItemPtr不管用，还请大侠多多指点。</P>
<P>谢谢你的回答！</P>

<P>ILegendItemPtr 的<a href="mk:@MSITStore:C:\Program%20Files\ArcGIS\DeveloperKit\Help\COM\VB\esriCarto.chm::/ILegendItem_Width.htm" target="_blank" ><STRONG>Width</STRONG></A>和<a href="mk:@MSITStore:C:\Program%20Files\ArcGIS\DeveloperKit\Help\COM\VB\esriCarto.chm::/ILegendItem_Height.htm" target="_blank" ><STRONG>Height</STRONG></A>移动要设置，它的大小直接影响到整体的字体大小，只要这个设置合适后，SYMBOL的字体大小是否设置都没关系</P>
