Qt Graphs Widgets
Widget support is included in its own module to avoid a hard dependency on QtWidgets when building only QML applications.
Using the Module
Using a Qt module's C++ API requires linking against the module library, either directly or through other dependencies. Several build tools have dedicated support for this, including CMake and qmake.
Building with CMake
Use the find_package() command to locate the needed module component in the Qt6 package:
find_package(Qt6 REQUIRED COMPONENTS GraphsWidgets)
target_link_libraries(mytarget PRIVATE Qt6::GraphsWidgets)
For more details, see the Build with CMake overview.
Building with qmake
To configure the module for building with qmake, add the module as a value of the QT variable in the project's .pro file:
QT += graphswidgets
