wx.SystemAppearance¶

Provides information about the current system appearance.

An object of this class can be retrieved using wx.SystemSettings.GetAppearance and can then be queried for some aspects of the current system appearance, notably whether the system is using a dark theme, i.e. a theme with predominantly dark background.

This is useful for custom controls that don’t use the standard system colours, as they need to adjust the colours used for drawing them to fit in the system look.

Note that this class is only used to query the current appearance, see wx.App.SetAppearance for changing it.

Added in version 4.1/wxWidgets-3.1.3.

Methods Summary¶

`AreAppsDark`	Return `True` if the applications on this system use dark theme by default.
`GetName`	Return the name if available or empty string otherwise.
`IsDark`	Return `True` if the current system there is explicitly recognized as being a dark theme or if the default window background is dark.
`IsSystemDark`	Return `True` if the system UI uses dark theme.
`IsUsingDarkBackground`	Return `True` if the default window background is significantly darker than foreground.

Class API¶

class wx.SystemAppearance(object)¶

Provides information about the current system appearance.

Methods¶

AreAppsDark(self)¶

Return True if the applications on this system use dark theme by default.

This function returns True if dark mode is enabled for the applications system-wide, even if it’s not enabled for this particular application.

Note that for non-MSW platforms this is currently the same as IsDark , but under MSW these two functions can return different values as dark mode requires to opt-in into it specifically.

Return type:: bool

Added in version 4.3/wxWidgets-3.3.0.

GetName(self)¶

Return the name if available or empty string otherwise.

This is currently only implemented for macOS and returns a not necessarily user-readable string such as “NSAppearanceNameAqua” there and an empty string under all the other platforms.

Return type:: str

IsDark(self)¶

Return True if the current system there is explicitly recognized as being a dark theme or if the default window background is dark.

This method should be used to check whether custom colours more appropriate for the default (light) or dark appearance should be used.

Note that this checks the appearance of the current application and not the other applications on the system, so under MSW, for example, it will return False even if dark mode is used system-wide unless the application opted in using dark mode using wx.App.MSWEnableDarkMode . You can use IsSystemDark or AreAppsDark to check if the system is using dark mode by default.

Return type:: bool

IsSystemDark(self)¶

Return True if the system UI uses dark theme.

This is the same as AreAppsDark on the non-MSW platforms, but can be different from the other function under MSW as it is possible to configure default “Windows mode” and “app mode” to use different colour schemes under Windows.

Return type:: bool

Added in version 4.3/wxWidgets-3.3.0.

IsUsingDarkBackground(self)¶

Return True if the default window background is significantly darker than foreground.

This is used by IsDark if there is no platform-specific way to determine whether a dark mode is being used and is generally not very useful to call directly.

Return type:: bool
