UI language changes are not applied until manual restart

[vlad.bezugliy]

Hi all. I use uno api for python and need to change UI language dynamically.

I use the following code:

import uno
local_context = uno.getComponentContext()
resolver = local_context.ServiceManager.createInstanceWithContext(
        "com.sun.star.bridge.UnoUrlResolver", local_context)
remote_context = resolver.resolve(connection_url) #my url here
service_manager = self.remote_context.getServiceManager()
desktop = service_manager.createInstanceWithContext(
        "com.sun.star.frame.Desktop", remote_context)

# set needed UI language
nodepath_prop = uno.createUnoStruct("com.sun.star.beans.PropertyValue")
nodepath_prop.Name = "nodepath"
nodepath_prop.Value = "org.openoffice.Office.Linguistic/General"

enableasync_prop = uno.createUnoStruct(
        "com.sun.star.beans.PropertyValue")
enableasync_prop.Name = "enableasync"
enableasync_prop.Value = True

config = service_manager.createInstanceWithContext(
        "com.sun.star.configuration.ConfigurationProvider",
        remote_context)

current_prop_state = config.createInstanceWithArguments(
        "com.sun.star.configuration.ConfigurationUpdateAccess",
        (nodepath_prop, enableasync_prop))

current_value = current_prop_state.getPropertyValue("UILocale")
if current_value != "ru":
      current_prop_state.replaceByName("UILocale", "ru")
      current_prop_state.commitChanges()
      config.flush()

document = desktop.loadComponentFromURL('private:factory/scalc', '_blank', 0, ())

But when document is open language is still not changed in UI (but changed in options, see screenshot)

How can I force Calc document to use options for UI via python code?

Note: when I restart Libre manually, language is applied correctly

When you change UI language manually, LO asks for instant restart for the change to take effect. There is no reason the underlying function behaves differently in a macro.

@ajlittoz, I agree, but what is restart in terms of macro? How can I do it via script

[ajlittoz]

No idea, I never wrote a macro.

the following macro does something more … saving timestamped copies … but should contain all the building blocks you need, reopening is realised via a shell call, not sure how exact you’ll meet your ‘closing point’, and still a challenge to continue with your macro … have fun …
