链接
<p>超链CHyperlink，继承于CTextView，支持CTextView的所有属性和方法。</p>
<h2>属性和相关方法</h2>
<h4>设置超链的链接URL</h4>
<ul>
<li>通过XML属性控制如下：</li>
</ul>
<pre><code class="language-xml">URL="www.baidu.com"</code></pre>
<ul>
<li>通过C++程序代码调用方法控制如下：</li>
</ul>
<pre><code class="language-c">void SetURL(const String& strURL);</code></pre>
<h2>2 消息处理</h2>
<h4>2.1 WM_COMMAND消息</h4>
<p>单击链接，鼠标左键抬起时，有两种情况：</p>
<ul>
<li>如果是URL，直接调用系统默认浏览器打开这个URL;</li>
<li>如果不是URL且Id不为0，会给链接所在的窗口发送WM_COMMAND消息。</li>
</ul>
<p>请参考下面的示例代码：</p>
<pre><code class="language-cpp">void CHyperlink::HandleLButtonUp(CPoint point, BOOL& bHandle)
{
CTextView::HandleLButtonUp(point, bHandle);
if(GetState() == PRESSED)
{
if(!m_strURL.empty())
{
SkinUI::OpenURL(m_strURL, GetOwner());
}
else if(GetId() != 0)
{
GetOwner()->PostMessage(WM_COMMAND, GetId(), reinterpret_cast<LPARAM>(this));
}
}
SetState(HOVER);
Redraw();
}</code></pre>
