Question

[A, count] = fscanf(fid,['%s %d, %s %d, %s %f, %s %d.'],[AnInstantNumberRelatedToTheLengthOfALine, numberOfRows]);

我将rsstail的输出分配给名为txt0的变量，然后我尝试将新闻变量中存在的rsstail输出值打印到文本字段，但我的文本字段不刷新当我点击两个按钮rsstail输出没有改变。两个按钮都是一样的。

Aaha将rsstail输出转换为文本文件解决了它。喜欢：

<hbox>
            <button>
              <input file>bbc_150x150.jpeg</input>
              <variable>bbc</variable>
              <action>echo $(eval rsstail -u newsrss.bbc.co.uk/rss/newsonline_uk_edition/front_page/rss.xml -u feeds.bbci.co.uk/news/system/latest_published_content/rss.xml -1 -n 3) > txt0.txt</action>
          <action>echo $txt0.txt</action>
          <action>refresh:txt0</action>
            </button>  
</hbox>

<hbox>

              <input file>bbcbusiness_150x150.jpeg</input>
              <action>rm txt0.txt</action>
              <action>echo $(eval rsstail -u newsrss.bbc.co.uk/rss/newsonline_uk_edition/business/rss.xml -1 -n 3)>txt0.txt</action>
            <action>echo $txt0.txt</action>
           <action>refresh:txt0</action>
            </button>  
</hbox>

<vbox scrollable="true" width="600" height="300">
                    <text wrap="false" xalign="0">
                        <variable>txt0</variable>
                        <label>This is a static text.</label>
                        <input file>txt0.txt</input>
                    </text>
</vbox>
