Qt Quick Controls support a special configuration file,
qtquickcontrols2.conf
, which is built into an application's resources.
The configuration file can specify the preferred style and certain style-specific attributes. The following example specifies that the preferred style is the 材质风格 . Furthermore, when the application is run with the Material style, its theme is light and the accent and primary colors are teal and blue grey, respectively. However, if the application is run with the Universal style instead, the accent color is red and the appropriate theme is chosen based on the system theme colors.
[Controls] Style=Material [Universal] Theme=System Accent=Red [Material] Theme=Light Accent=Teal Primary=BlueGrey
It is possible to specify a custom location for the configuration file with the QT_QUICK_CONTROLS_CONF 环境变量。
The following values can be specified in a
Controls

| 变量 | 描述 |

见 Palette QML type for more information.
In order to make it possible for Qt Quick Controls to find the configuration file, it must be built into application's resources using the
Qt 资源系统
. Here's an example
.qrc
文件：
<!DOCTYPE RCC><RCC version="1.0"> <qresource prefix="/"> <file>qtquickcontrols2.conf</file> </qresource> </RCC>
注意： Qt Quick Controls uses a file selector to load the configuration file. It is possible to provide a different configuration file for different platforms and locales. See QFileSelector 文档编制了解更多细节。
Finally, the
.qrc
file must be listed in the application's build file. For example:
set(CMAKE_AUTORCC ON)
qt_add_executable(my_app
application.qrc
main.cpp
...
)
