3.11 进度条
<p>进度条由CSkinProgress类来代表，继承于CSkinView，支持CSkinView的所有属性和方法。</p>
<p>通过给进度条设置不同的图片资源，可以得到各种形态的进度条。</p>
<h2>1 属性和相关方法：</h2>
<h4>1.1设置进度条的最大进度</h4>
<ul>
<li>通过XML属性控制如下：
<pre><code class="language-xml">Range=&quot;100&quot;</code></pre></li>
<li>通过C++程序代码调用方法控制如下：
<pre><code class="language-c">void SetRange(uint64 nRange);</code></pre></li>
</ul>
<h4>1.2设置进度条的当前进度</h4>
<ul>
<li>通过XML属性控制如下：
<pre><code class="language-xml">Pos=&quot;1&quot;</code></pre></li>
<li>通过C++程序代码调用方法控制如下：
<pre><code class="language-c">void SetPos(uint64 nPos);</code></pre></li>
</ul>
<h2>请看下面的示例</h2>
