qt - 结合 Qt Widgets 和 QML 与 QWidget::createWindowContainer()

Question

我试着关注这篇文章:

如果我尝试重做，我会得到这个错误:

15:13:36: Running steps for project Test_QMLWidgets01... 15:13:36: Configuration unchanged, skipping qmake step. 15:13:36: Starting: "C:\Qt\Qt5\Tools\QtCreator\bin\jom.exe" C:\Qt\Qt5\Tools\QtCreator\bin\jom.exe -f Makefile.Debug cl -c -nologo -Zm200 -Zc:wchar_t -Zi -MDd -GR -W3 -w34100 -w34189 -EHsc -DUNICODE -DWIN32 -DQT_QML_DEBUG -DQT_DECLARATIVE_DEBUG -DQT_WIDGETS_LIB -DQT_GUI_LIB -DQT_CORE_LIB -DQT_OPENGL_ES_2 -DQT_OPENGL_ES_2_ANGLE -I"C:\Qt\Qt5\5.1.0\msvc2010\include" -I"C:\Qt\Qt5\5.1.0\msvc2010\include\QtWidgets" -I"C:\Qt\Qt5\5.1.0\msvc2010\include\QtGui" -I"C:\Qt\Qt5\5.1.0\msvc2010\include\QtANGLE" -I"C:\Qt\Qt5\5.1.0\msvc2010\include\QtCore" -I"debug" -I"." -I"." -I"C:\Qt\Qt5\5.1.0\msvc2010\mkspecs\win32-msvc2010" -Fodebug\ @C:\Users\VANBEB~1\AppData\Local\Temp\mainwindow.obj.3328.0.jom mainwindow.cpp ..\Test_QMLWidgets01\mainwindow.cpp(2) : fatal error C1083: Cannot open include file: 'QQuickView': No such file or directory jom: E:\QtProjects\build-Test_QMLWidgets01-Desktop_Qt_5_1_0_MSVC2010_32bit-Debug\Makefile.Debug [debug\mainwindow.obj] Error 2 jom: E:\QtProjects\build-Test_QMLWidgets01-Desktop_Qt_5_1_0_MSVC2010_32bit-Debug\Makefile [debug] Error 2 15:13:36: The process "C:\Qt\Qt5\Tools\QtCreator\bin\jom.exe" exited with code 2.

所以我将#include 更改为#include 但随后出现链接错误:
