如何同步两个RichEdit的滚动位置？

// 假设有两个RichEdit控件的句柄为hSourceRichEdit和hTargetRichEdit

// 获取源RichEdit控件的滚动位置
SCROLLINFO sourceScrollInfo;
sourceScrollInfo.cbSize = sizeof(SCROLLINFO);
sourceScrollInfo.fMask = SIF_POS;
GetScrollInfo(hSourceRichEdit, SB_VERT, &sourceScrollInfo);
int sourceScrollPos = sourceScrollInfo.nPos;

// 将滚动位置应用到目标RichEdit控件上
SCROLLINFO targetScrollInfo;
targetScrollInfo.cbSize = sizeof(SCROLLINFO);
targetScrollInfo.fMask = SIF_POS;
targetScrollInfo.nPos = sourceScrollPos;
SetScrollInfo(hTargetRichEdit, SB_VERT, &targetScrollInfo, TRUE);
RedrawWindow(hTargetRichEdit, NULL, NULL, RDW_INVALIDATE | RDW_ERASE);

// 监听源RichEdit控件的滚动事件
// 在源RichEdit控件的滚动事件处理函数中更新目标RichEdit控件的滚动位置
// 以下代码仅为示例，具体实现需根据实际情况编写
LRESULT CALLBACK SourceRichEditScrollWndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam, UINT_PTR uIdSubclass, DWORD_PTR dwRefData)
{
    switch (msg)
    {
        case WM_VSCROLL:
        {
            // 更新目标RichEdit控件的滚动位置
            SCROLLINFO sourceScrollInfo;
            sourceScrollInfo.cbSize = sizeof(SCROLLINFO);
            sourceScrollInfo.fMask = SIF_POS;
            GetScrollInfo(hSourceRichEdit, SB_VERT, &sourceScrollInfo);
            int sourceScrollPos = sourceScrollInfo.nPos;

            SCROLLINFO targetScrollInfo;
            targetScrollInfo.cbSize = sizeof(SCROLLINFO);
            targetScrollInfo.fMask = SIF_POS;
            targetScrollInfo.nPos = sourceScrollPos;
            SetScrollInfo(hTargetRichEdit, SB_VERT, &targetScrollInfo, TRUE);
            RedrawWindow(hTargetRichEdit, NULL, NULL, RDW_INVALIDATE | RDW_ERASE);
        }
        break;
    }
    return DefSubclassProc(hwnd, msg, wParam, lParam);
}

// 在源RichEdit控件上设置滚动事件处理函数
SetWindowSubclass(hSourceRichEdit, SourceRichEditScrollWndProc, 0, 0);
