Class Details

class Adw.StyleManager(**kwargs)
Bases:

GObject.Object

Abstract:

No

Structure:

Adw.StyleManagerClass

A class for managing application-wide styling.

AdwStyleManager provides a way to query and influence the application styles, such as whether to use dark or high contrast appearance.

It allows to set the color scheme via the [property`StyleManager`:py:data::color-scheme<Adw.StyleManager.props.color_scheme>] property, and to query the current appearance, as well as whether a system-wide color scheme preference exists.

classmethod get_default()
Returns:

the default style manager

Return type:

Adw.StyleManager

Gets the default AdwStyleManager instance.

It manages all [class`Gdk`.Display] instances unless the style manager for that display has an override.

See [func`StyleManager`.get_for_display].

classmethod get_for_display(display)
Parameters:

display (Gdk.Display) – a GdkDisplay

Returns:

the style manager for display

Return type:

Adw.StyleManager

Gets the AdwStyleManager instance managing display.

It can be used to override styles for that specific display instead of the whole application.

Most applications should use [func`StyleManager`.get_default] instead.

get_color_scheme()
Returns:

the color scheme

Return type:

Adw.ColorScheme

Gets the requested application color scheme.

get_dark()
Returns:

whether the application is using dark appearance

Return type:

bool

Gets whether the application is using dark appearance.

This can be used to query the current appearance, as requested via [property`StyleManager`:py:data::color-scheme<Adw.StyleManager.props.color_scheme>].

get_display()
Returns:

the display

Return type:

Gdk.Display or None

Gets the display the style manager is associated with.

The display will be NULL for the style manager returned by [func`StyleManager`.get_default].

get_high_contrast()
Returns:

whether the application is using high contrast appearance

Return type:

bool

Gets whether the application is using high contrast appearance.

This cannot be overridden by applications.

get_system_supports_color_schemes()
Returns:

whether the system supports color schemes

Return type:

bool

Gets whether the system supports color schemes.

This can be used to check if the current environment provides a color scheme preference. For example, applications might want to show a separate appearance switcher if it’s set to FALSE.

set_color_scheme(color_scheme)
Parameters:

color_scheme (Adw.ColorScheme) – the color scheme

Sets the requested application color scheme.

The effective appearance will be decided based on the application color scheme and the system preferred color scheme. The [property`StyleManager`:py:data::dark<Adw.StyleManager.props.dark>] property can be used to query the current effective appearance.

The ADW_COLOR_SCHEME_PREFER_LIGHT color scheme results in the application using light appearance unless the system prefers dark colors. This is the default value.

The ADW_COLOR_SCHEME_PREFER_DARK color scheme results in the application using dark appearance, but can still switch to the light appearance if the system can prefers it, for example, when the high contrast preference is enabled.

The ADW_COLOR_SCHEME_FORCE_LIGHT and ADW_COLOR_SCHEME_FORCE_DARK values ignore the system preference entirely. They are useful if the application wants to match its UI to its content or to provide a separate color scheme switcher.

If a per-[class`Gdk`.Display] style manager has its color scheme set to ADW_COLOR_SCHEME_DEFAULT, it will inherit the color scheme from the default style manager.

For the default style manager, ADW_COLOR_SCHEME_DEFAULT is equivalent to ADW_COLOR_SCHEME_PREFER_LIGHT.

The [property`StyleManager`:py:data::system-supports-color-schemes<Adw.StyleManager.props.system_supports_color_schemes>] property can be used to check if the current environment provides a color scheme preference.

Name:

color-scheme

Type:

Adw.ColorScheme

Default Value:

Adw.ColorScheme.DEFAULT

Flags:

READABLE, WRITABLE, EXPLICIT_NOTIFY

The requested application color scheme.

The effective appearance will be decided based on the application color scheme and the system preferred color scheme. The [property`StyleManager`:py:data::dark<Adw.StyleManager.props.dark>] property can be used to query the current effective appearance.

The ADW_COLOR_SCHEME_PREFER_LIGHT color scheme results in the application using light appearance unless the system prefers dark colors. This is the default value.

The ADW_COLOR_SCHEME_PREFER_DARK color scheme results in the application using dark appearance, but can still switch to the light appearance if the system can prefers it, for example, when the high contrast preference is enabled.

The ADW_COLOR_SCHEME_FORCE_LIGHT and ADW_COLOR_SCHEME_FORCE_DARK values ignore the system preference entirely. They are useful if the application wants to match its UI to its content or to provide a separate color scheme switcher.

If a per-[class`Gdk`.Display] style manager has its color scheme set to ADW_COLOR_SCHEME_DEFAULT, it will inherit the color scheme from the default style manager.

For the default style manager, ADW_COLOR_SCHEME_DEFAULT is equivalent to ADW_COLOR_SCHEME_PREFER_LIGHT.

The [property`StyleManager`:py:data::system-supports-color-schemes<Adw.StyleManager.props.system_supports_color_schemes>] property can be used to check if the current environment provides a color scheme preference.

Adw.StyleManager.props.dark

Name:

display

Type:

Gdk.Display

Default Value:

None

Flags:

Name:

system-supports-color-schemes

Type:

bool
