    可以根据窗口布局或HKL获取输入名字，windows消息WM_INPUTLANGCHANGE的LPARAM就是HKL

    QString getImeNameFromHKL(HKL hkl) {
	const int BUF_LEN = 1024;
	wchar_t buf[BUF_LEN] = { 0 };
	ImmGetIMEFileName(hkl, buf, BUF_LEN - 2);
	QString result = QString::fromStdWString(buf);
	return result;
}

QString getImeNameFromWnd(HWND hwnd) {
	DWORD threadId = GetWindowThreadProcessId(hwnd, NULL);
	HKL hkl = GetKeyboardLayout(threadId);
	return getImeNameFromHKL(hkl);
}

    调整输入法候选框位置

    HIMC himc = ImmGetContext(hwnd);
CANDIDATEFORM cand;
cand.dwIndex = 0;
cand.dwStyle = CFS_CANDIDATEPOS;
cand.ptCurrentPos.x = 0;
cand.ptCurrentPos.y = 0;
ImmSetCandidateWindow(himc, &cand);
ImmReleaseContext(hwnd, himc);

    包含头文件

    #include <Windows.h>
#pragma comment(lib, "Imm32.lib")

    支持win7及以下系统，win8及以上的系统可能用的新输入法框架
