a11y: Introduce QAccessible::Attribute::Locale, bridge to AT-SPIHEADdev
Introduce a new Locale value for the QAccessible::Attribute enum class that can be used to specify the locale of an accessible object. Use this to implement support for the "Locale" property of the AT-SPI Accessible interface. [1] If no locale has explicitly been specified, report the default locale in the AT-SPI adaptor, as is already the case in the implementation of the "GetLocale" method of the AT-SPI Application interface. Being able to explicitly specify a locale is of particular interest when an application contains objects whose locale differs from the default application locale, e.g. documents or paragraphs written in a different language. Demo LibreOffice change making use of this new API: [2] Sample use case with the above-mentioned LibreOffice change in place: 1) start LibreOffice Writer, using English UI and document language 2) type "Hello world" for the first paragraph 3) press Enter to create a new paragraph 4) copy-paste "你好世界" ("Hello world" in Chinese) into the new paragraph 5) start Accerciser 6) select the first paragraph in Accerciser's treeview of the LibreOffice a11y hierarchy 7) query locale in Accerciser's IPython console In [1]: acc.get_object_locale() Out[1]: 'en_GB' 8) select the second paragraph in Accerciser's treeview of the LibreOffice a11y hierarchy 9) query locale in Accerciser's IPython console In [2]: acc.get_object_locale() Out[2]: 'zh_CN' For UIA on Windows, UIA_CulturePropertyId [3] seems to be the equivalent property that the new attribute could be mapped to (to be done separately, not implemented in this commit).
