Using Styles in Qt Quick Controls 2

In order to run an application with a specific style, either configure the style using QQuickStyle in C++, pass a command line argument, or set an environment variable. Alternatively, the preferred style and style-specific attributes can be specified in a configuration file.

The priority of these approaches follows the order they are listed below, from highest to lowest. That is, using QQuickStyle to set the style will always take priority over using the command line argument, for example.

使用 QQuickStyle 在 C++

QQuickStyle provides C++ API for configuring a specific style. The following example runs a Qt Quick Controls 2 application with the Material style:

QQuickStyle::setStyle("Material");

命令行自变量

Passing a -style command line argument is the convenient way to test different styles. It takes precedence over the other methods listed below. The following example runs a Qt Quick Controls 2 application with the Material style:

./app -style material
					

环境变量

设置 QT_QUICK_CONTROLS_STYLE environment variable can be used to set a system-wide style preference. It takes precedence over the configuration file mentioned below. The following example runs a Qt Quick Controls 2 application with the Universal style:

QT_QUICK_CONTROLS_STYLE=universal ./app
