1.8 消息处理
<h3>11.2.1 命令消息处理</h3>
<h3>11.2.1.1 单命令消息处理</h3>
<p>一个控件Id绑定一个消息处理函数，如下所示：</p>
<ul>
<li>
<p>头文件</p>
<pre><code class="language-c">void OnBtnClickedCommand(UINT uNotifyCode, int nID, CSkinView* pView);
SKINUI_DECLARE_MESSAGE_MAP()</code></pre>
</li>
<li>源文件
<pre><code class="language-c">SKINUI_BEGIN_MESSAGE_MAP(CMainDialog, CSkinDialog)
ON_SKINUI_COMMAND(IDC_BUTTON, OnBtnClickedCommand)
SKINUI_END_MESSAGE_MAP()
void CMainDialog::OnBtnClickedCommand(UINT uNotifyCode, int nID, CSkinView* pView)
{
}</code></pre></li>
</ul>
<h3>11.2.1.2 范围命令消息处理</h3>
<p>一个控件Id范围绑定一个消息处理函数，如下所示：</p>
<ul>
<li>
<p>头文件</p>
<pre><code class="language-c">void OnBtnClickedCommand(UINT uNotifyCode, int nID, CSkinView* pView);
SKINUI_DECLARE_MESSAGE_MAP()</code></pre>
</li>
<li>源文件
<pre><code class="language-c">SKINUI_BEGIN_MESSAGE_MAP(CMainDialog, CSkinDialog)

SKINUI_END_MESSAGE_MAP()
void CMainDialog::OnBtnClickedCommand(UINT uNotifyCode, int nID, CSkinView* pView)
{
}</code></pre></li>
</ul>
<h3>11.2.1.3 更新UI命令消息处理</h3>
<p>SkinUI会在需要的时候发送更新UI命令消息用来更新UI组件的状态。主要存在以下几种情况：</p>
<ul>
<li>按钮的禁用；</li>
<li>菜单的禁用；</li>
<li>菜单的选中；</li>
</ul>
<h4>按钮的禁用：</h4>
<ul>

</li>
<li>源文件
<pre><code class="language-c">SKINUI_BEGIN_MESSAGE_MAP(CMainDialog, CSkinDialog)
ON_SKINUI_UPDATE_COMMAND_UI(IDC_BUTTON, OnUpdateCommandUI)
SKINUI_END_MESSAGE_MAP()
void CMainDialog::OnUpdateCommandUI(CSkinView* pView)
{
pView-&gt;SetEnable(FALSE);
}</code></pre></li>
</ul>
<h4>菜单的禁用：</h4>
<ul>
<li>
<p>头文件</p>
<pre><code class="language-c">void OnUpdateCommandUI(CSkinView* pView);

</li>
<li>源文件
<pre><code class="language-c">SKINUI_BEGIN_MESSAGE_MAP(CMainDialog, CSkinDialog)
ON_SKINUI_UPDATE_COMMAND_UI(IDC_MENU, OnUpdateCommandUI)
SKINUI_END_MESSAGE_MAP()
void CMainDialog::OnUpdateCommandUI(CSkinView* pView)
{
pView-&gt;SetEnable(FALSE);
}</code></pre></li>
</ul>
<h4>菜单的选中：</h4>
<ul>
<li>
<p>头文件</p>
<pre><code class="language-c">void OnUpdateCommandUI(CSkinView* pView);
SKINUI_DECLARE_MESSAGE_MAP()</code></pre>
</li>
<li>源文件
<pre><code class="language-c">SKINUI_BEGIN_MESSAGE_MAP(CMainDialog, CSkinDialog)
ON_SKINUI_UPDATE_COMMAND_UI(IDC_MENU, OnUpdateCommandUI)
SKINUI_END_MESSAGE_MAP()
void CMainDialog::OnUpdateCommandUI(CSkinView* pView)
{
pView-&gt;SetSelected(TRUE);
}</code></pre></li>
</ul>
<h3>11.2.2 非命令消息处理</h3>
<p>SkinUI内置了一些消息，可以自动解析消息的参数，参考下面的消息映射宏：</p>
<ul>
<li>ON_SKINUI_WM_CREATE()</li>
<li>ON_SKINUI_WM_PAINT()</li>
<li>ON_SKINUI_WM_ERASEBKGND()</li>
<li>ON_SKINUI_WM_SETCURSOR()</li>
<li>ON_SKINUI_WM_DESTROY()</li>
<li>ON_SKINUI_WM_SETFOCUS()</li>
<li>ON_SKINUI_WM_NCDESTROY()</li>
<li>ON_SKINUI_WM_NCLBUTTONDOWN()</li>
<li>ON_SKINUI_WM_KILLFOCUS()</li>
<li>ON_SKINUI_WM_SIZE()</li>
<li>ON_SKINUI_WM_SYSKEYDOWN()</li>
<li>ON_SKINUI_WM_SYSKEYUP()</li>
<li>ON_SKINUI_WM_KEYDOWN()</li>
<li>ON_SKINUI_WM_KEYUP()</li>
<li>ON_SKINUI_WM_CHAR()</li>
<li>ON_SKINUI_WM_SIZING()</li>
<li>ON_SKINUI_WM_LBUTTONDOWN()</li>
<li>ON_SKINUI_WM_LBUTTONUP()</li>
<li>ON_SKINUI_WM_RBUTTONDOWN()</li>
<li>ON_SKINUI_WM_RBUTTONUP()</li>
<li>ON_SKINUI_WM_LBUTTONDBLCLK()</li>
<li>ON_SKINUI_WM_MOUSEMOVE()</li>
<li>ON_SKINUI_WM_MOUSEHOVER()</li>
<li>ON_SKINUI_WM_MOUSELEAVE()</li>
<li>ON_SKINUI_WM_MOUSEWHEEL()</li>
<li>ON_SKINUI_WM_NCHITTEST()</li>
<li>ON_SKINUI_WM_GETMINMAXINFO()</li>
<li>ON_SKINUI_WM_TIMER()</li>
<li>ON_SKINUI_WM_SYSCOMMAND()</li>
<li>ON_SKINUI_WM_CLOSE()</li>
<li>ON_SKINUI_WM_MOVE()</li>

<li>ON_SKINUI_WM_IME_ENDCOMPOSITION()</li>
<li>ON_SKINUI_WM_IME_COMPOSITION()</li>
<li>ON_SKINUI_WM_DISPLAYCHANGE()</li>
</ul>
<h3>11.2.2.1 自动解析参数的消息处理</h3>
<p>上面的消息，可以由SkinUI自动解析参数。参考下面的示例：</p>
<ul>
<li>
<p>头文件</p>
<pre><code class="language-c">void OnLButtonDown(UINT nFlags, CPoint point, BOOL&amp; bHandle);
SKINUI_DECLARE_MESSAGE_MAP()</code></pre>
</li>
<li>源文件
<pre><code class="language-c">SKINUI_BEGIN_MESSAGE_MAP(CMainDialog, CSkinDialog)
ON_SKINUI_WM_RBUTTONDOWN()
SKINUI_END_MESSAGE_MAP()
void CMainDialog::OnLButtonDown(UINT nFlags, CPoint point, BOOL&amp; bHandle)
{
}</code></pre></li>
</ul>
<h3>11.2.2.2 手动解析参数的消息处理</h3>
<p>用户自定义消息和未提供自动解析参数的系统消息，不能自动解析参数，需要开发者手动解析。参考下面的示例：</p>
<ul>
<li>
<p>头文件</p>
<pre><code class="language-c">LRESULT OnComboBoxSelChange(WPARAM wParam, LPARAM lParam);
SKINUI_DECLARE_MESSAGE_MAP()</code></pre>
</li>
<li>源文件
<pre><code class="language-c">SKINUI_BEGIN_MESSAGE_MAP(CMainDialog, CSkinDialog)
ON_SKINUI_MESSAGE(WM_COMBOBOX_SEL_CHANGE, OnComboBoxSelChange)
SKINUI_END_MESSAGE_MAP()
LRESULT CMainDialog::OnComboBoxSelChange(WPARAM wParam, LPARAM lParam)
{
if(wParam == CChatRecordChildLayout::IDC_BUTTON_COMBOBOX)
{
CSkinComboBox* pComboBox = reinterpret_cast&lt;CSkinComboBox*&gt;(lParam);
}
return 1L;
}</code></pre></li>
</ul>
