热键选择框
<p>热键选择框CHotKeyView，继承于CEditView，支持CEditView的所有属性和方法。</p>
<h2>消息处理</h2>
<h4>WM_HOTKEY_CHANGE</h4>
<p>热键列表框的值发生变化时，会给所在窗口发送自定义消息WM_HOTKEY_CHANGE。</p>
<p>参考下面的示例代码：</p>
<pre><code class="language-cpp">void CHotKeyView::HandleKeyDown(TCHAR vkey, UINT repeats, UINT code, BOOL& bHandle)
{
String strVirtualKeyCode = CStringHelper::VirtualKeyCodeToString(vkey);
if(!strVirtualKeyCode.empty())
{
m_bKeyUpClear = FALSE;
m_wVirtualKeyCode = vkey;
m_wModifiers = CMiscHelper::GetCurModifiers();
if(m_wModifiers == 0 && CMiscHelper::NeedDefaultModifiers(vkey))
{
m_wModifiers = 3;
}
SetText(CStringHelper::ModifiersToString(m_wModifiers) + strVirtualKeyCode);
GetOwner()->SendMessage(WM_HOTKEY_CHANGE, GetId(), reinterpret_cast<LPARAM>(this));
}
else
{
m_wModifiers = 0;
m_wVirtualKeyCode = 0;
m_bKeyUpClear = TRUE;
if(vkey == VK_SHIFT || vkey == VK_CONTROL || vkey == VK_MENU)
{
WORD wModifiers = CMiscHelper::GetCurModifiers();
String strModifiers = CStringHelper::ModifiersToString(wModifiers);
SetText(strModifiers);
}
else if(vkey == VK_BACK || vkey == VK_DELETE || vkey == VK_RETURN)
{
SetText(String());
}
}
bHandle = TRUE;
}</code></pre>
