C++ (Cpp) IsThemeEnabled Examples

Example #1

File: FeedIcoItemListCtrl.cpp Project: techpub/archive-code

void CFeedIcoItemListCtrl::OnLvnHotTrack(NMHDR *pNMHDR, LRESULT *pResult)
{
	// vista+ 系统的经典主题和vista-系统的 必须要加此消息
	if (thePrefs.GetWindowsVersion() >= _WINVER_VISTA_ && IsThemeEnabled())
		return;

	LPNMLISTVIEW pNMLV = reinterpret_cast<LPNMLISTVIEW>(pNMHDR);
	// TODO: Add your control notification handler code here
	*pResult = 0;

	int nCurrentHotItemIndex = GetHotItem();

	if (nCurrentHotItemIndex == m_nLastHotItemIndex)
		return;

	if (-1 != nCurrentHotItemIndex)
	{// move into the hot item
		m_nLastHotItemIndex = nCurrentHotItemIndex;
	}
	else
	{// move out of the hot item
		nCurrentHotItemIndex = m_nLastHotItemIndex;
		m_nLastHotItemIndex = -1;
	}

	CRect itemRect(0,0,0,0);
	GetItemRect(nCurrentHotItemIndex, &itemRect, LVIR_BOUNDS);

	InvalidateRect(&itemRect);
}
