MFC中的Spin control控件對(duì)應(yīng)WTL中的CUpDownCtrl控件，CUpDownCtrl控件通過(guò)SetBuddy()方法綁定需要上下選擇控件的窗口，典型的就是Edit控件。下面來(lái)看代碼：
WTL::CRichEditCtrl m_recCount;
WTL::CUpDownCtrl m_upcCount;
WTL::CRect m_rcCount;
// 初始化
m_rcCount = WTL::CRect(0, 0, width, 20);
//
void SetupEdit()
{
// Count rich edit
m_recCount.Create(
*this,
m_rcCount,
L"",
WS_CHILD | WS_VISIBLE | WS_TABSTOP | ES_NUMBER | ES_LEFT,
0);
m_upcCount.Create(
*this,
m_rcCount,
L"",
WS_CHILD | WS_VISIBLE | UDS_ALIGNRIGHT | UDS_AUTOBUDDY | UDS_SETBUDDYINT,
0);
m_upcCount.SetBuddy(m_recCount);
m_upcCount.SetRange(1, m_maxCount);
m_upcCount.SetPos(1);
}
