Member Function Documentation

[static] void QQuickStyle::addStylePath(const QString &path)

Adds path as a directory where Qt Quick Controls 2 searches for available styles.

The path may be any local filesystem directory or Qt Resource directory. For example, the following paths are all valid:

• /path/to/styles/
• file:///path/to/styles/
• :/path/to/styles/
• qrc:/path/to/styles/)

The path will be converted into canonical form before it is added to the style path list.

The newly added path will be first in the stylePathList().

This function was introduced in Qt 5.12.

See also stylePathList() and availableStyles().

[static] QStringList QQuickStyle::availableStyles()

Returns the names of the available styles.

Note: The method must be called after creating an instance of QGuiApplication.

This function was introduced in Qt 5.9.

See also stylePathList() and addStylePath().

[static] QString QQuickStyle::name()

Returns the name of the application style.

Note: The application style can be specified by passing a -style command line argument. Therefore name() may not return a fully resolved value if called before constructing a QGuiApplication.

[static] QString QQuickStyle::path()

Returns the path of an overridden application style, or an empty string if the style is one of the built-in Qt Quick Controls 2 styles.

Note: The application style can be specified by passing a -style command line argument. Therefore path() may not return a fully resolved value if called before constructing a QGuiApplication.

[static] void QQuickStyle::setFallbackStyle(const QString &style)

Sets the application fallback style to style.

Note: The fallback style must be the name of one of the built-in Qt Quick Controls 2 styles, e.g. "Material".

Note: The style must be configured before loading QML that imports Qt Quick Controls 2. It is not possible to change the style after the QML types have been registered.

The fallback style can be also specified by setting the QT_QUICK_CONTROLS_FALLBACK_STYLE environment variable.

This function was introduced in Qt 5.8.

See also setStyle() and Using Styles in Qt Quick Controls 2.

[static] void QQuickStyle::setStyle(const QString &style)

Sets the application style to style.

Note: The style must be configured before loading QML that imports Qt Quick Controls 2. It is not possible to change the style after the QML types have been registered.

See also setFallbackStyle() and Using Styles in Qt Quick Controls 2.

[static] QStringList QQuickStyle::stylePathList()

Returns the list of directories where Qt Quick Controls 2 searches for available styles.

By default, the list contains paths specified in the QT_QUICK_CONTROLS_STYLE_PATH environment variable, and any existing QtQuick/Controls.2 sub-directories in QQmlEngine::importPathList().

This function was introduced in Qt 5.12.
