Qt 5 Core Compatibility APIs

The Qt 5 Core Compat module contains the Qt 5 Core APIs that were removed in Qt 6. The module facilitates the transition to Qt 6.

使用模块

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 .

构建采用 CMake

使用 find_package() command to locate the needed module component in the Qt6 包：

find_package(Qt6 REQUIRED COMPONENTS Core5Compat)
target_link_libraries(mytarget PRIVATE Qt6::Core5Compat)

更多细节，见构建采用 CMake 概述。

采用 qmake 构建

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 += core5compat
