Bootstrap 4可切换导航栏

我正在尝试从Bootstrap 3.x迁移到4,我遇到了新的导航栏问题.无论我选择哪种navbar-toggleable-x选项,导航栏总会显示汉堡包按钮,就像折叠一样.

这个HTML文档演示了我的问题.我在官方文档页面上找到了它.

与下落阴影的无边框窗口

我正在努力实现像Visual Studio安装程序那样的无边框窗口和投影:

我尝试了各种选项,比如CS_DROPSHADOW和DWM API,但是一旦我应用了WS_THICKFRAME样式,阴影就消失了.

这是我创建和居中窗口的代码:

RECT R = {0, 0, _clientWidth, _clientHeight};
AdjustWindowRect(&R, WS_OVERLAPPEDWINDOW, false);
_mainWnd = CreateWindow(L"D3DWndClassName", _mainWndCaption.c_str(), WS_OVERLAPPEDWINDOW, 100, 100, R.right, R.bottom, nullptr, nullptr, _appInst, nullptr);

if(!_mainWnd){
    MessageBox(nullptr, L"CreateWindow FAILED", nullptr, 0);
    PostQuitMessage(0);
}

RECT rc;

GetWindowRect(_mainWnd, &rc);

LONG lStyle = GetWindowLong(_mainWnd, GWL_STYLE);
lStyle &= ~(WS_CAPTION | WS_THICKFRAME | WS_MINIMIZE | WS_MAXIMIZE | WS_SYSMENU );
SetWindowLong(_mainWnd, GWL_STYLE, lStyle);


int xPos = (GetSystemMetrics(SM_CXSCREEN) - rc.right) / 2;
int yPos = (GetSystemMetrics(SM_CYSCREEN) - rc.bottom) / 2; …
