当我移动轨迹栏时，如何防止 Windows 通用控件 6.0 中的控件（选项卡）闪烁和消失？

滑动滑动条并释放鼠标按钮时，整个窗口都会闪烁，并且选项卡会消失。

当我使用旧版本时，一切正常！

当我使用新的 Microsoft Windows Common Controls ver.6.0 时，出现此问题！

}

这就是整个计划。

我举一个紧凑的例子。

如果你运行它，你就会看到问题。

如果您评论新控件，问题就会消失。

选项卡控件通用控件不会为您管理单独的内容窗格，因此如果您希望该跟踪栏成为选项卡控件的子项，并按照我们期望选项卡控件的工作方式工作，则需要管理子窗格你自己。

您可以使用“TabCtrl_AdjustRect”来计算子窗格需要有多大。请参阅对代码进行以下修改，例如：

#define TAB_ID 2000

HWND hWin, hTab;
HWND g_tabPanes[2];

HWND CreateTabPane(HWND tabctrl, int id, HINSTANCE instance)
{
    RECT rcTab;
    GetClientRect(tabctrl, &rcTab);
    TabCtrl_AdjustRect(tabctrl, FALSE, &rcTab);
    int wd = rcTab.right - rcTab.left;
    int hgt = rcTab.bottom - rcTab.top;
    return CreateWindow(
        L"static", L"", 
        WS_CHILD | WS_VISIBLE | WS_CLIPSIBLINGS, 
        rcTab.left, rcTab.top, wd, hgt, 
        tabctrl, 
        (HMENU) id, 
        instance, 
        NULL
    );
}

            RECT rc; int dx, dy;

            GetClientRect(hWnd, &rc);
