单选框
<p>超链CRadioButton，继承于CButton，支持CButton的所有属性和方法。</p>
<h2>属性和相关方法</h2>
<h4>设置单选框是否选中</h4>
<ul>
<li>通过XML属性控制如下：</li>
</ul>
<pre><code class="language-xml">Checked="true"</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">virtual void SetChecked(BOOL bChecked);</code></pre>
<h4>设置单选框绑定的视图</h4>
<ul>
<li>通过XML属性控制如下：</li>
</ul>
<pre><code class="language-xml">BindView="1001"</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 SetBindView(LONG nBindView);</code></pre>
<h2>消息处理</h2>
<h4>WM_RADIO_GROUP_CHECKED_CHANGE</h4>
<p>单选框一般作为CRadioGroup的子控件，这样可以用来做互斥的选择。当CRadioGroup的选中状态发生变化时，会切换绑定的视图，同时会给所在窗口发送自定义消息WM_RADIO_GROUP_CHECKED_CHANGE。</p>
<ul>
<li>参考下面的示例代码：</li>
</ul>
<pre><code class="language-cpp">void CRadioGroup::SetChecked(CRadioButton* pRadioButton)
{
CRadioButton* pOldChecked = GetChecked();
CRadioButton* pNewChecked = pRadioButton;
if(pOldChecked == pNewChecked)
{
return;
}
CRedrawLocker locker(GetOwner());
if(pNewChecked)
{
pNewChecked->SetChecked(TRUE);
}
if(pOldChecked)
{
pOldChecked->SetChecked(FALSE);
if(pOldChecked->IsVisible())
{
pOldChecked->SetState(NORMAL);
}
}
CView* pBindView = GetBindView(pNewChecked);
if(pBindView)
{
CSwitchLayout* pAnimationView = dynamic_cast<CSwitchLayout*>(pBindView->GetParent());
if(pAnimationView)
{
pAnimationView->Show(pBindView);
}
else
{
pBindView->SetState(NORMAL);
CView* pBindView = GetBindView(pOldChecked);
if(pBindView)
{
pBindView->SetState(HIDED);
}
}
}
GetOwner()->SendMessage(WM_RADIO_GROUP_CHECKED_CHANGE, GetId(), reinterpret_cast<LPARAM>(this));
}</code></pre>
