Change of localisation at runtime

General JUCE discussion

Hi Julian, hi everyone,

I started playing with LocalisedStrings in my app and encountered a problem when trying to change the localisation at runtime:

I can’t find a way to trigger a repaint of the whole app so that every displayed text can be updated with the new translation…

Any idea ?

(I noticed Tracktion requires a restart for that…)

Thanx in advance !

Calling the setCurrentMappings() would do the trick, wouldn’t it?

Of course, it’d be up to you to do any repainting, or refreshing of text that your app would need.

Of course setCurrentMappings() changes the current mapping in the LocalisedStrings instance but i was wondering if there was a way to force the whole app to repaint itself in one shot instead of calling repaint() on every concerned component…?

If that’s all you need, just do a repaint of the top-level window.

In fact, i had tried this but it seemed not to work with my MenuBarComponent…
I just realized menu bar texts had to be invalidated by calling MenuBarModel::menuItemsChanged() ! Sorry for the inconvenience :slight_smile:

And what about any other TopLevelWindow (e.g. AlertWindow or DialogWindow) which can be displayed when changing of language? No other way than calling repaint on each one ?

Anyway, thanx for your answer !

Not much point calling repaint on an AlertWindow, you’d need give it an updated string to display. Likewise a lot of components that just show some text that you’ve previously given it.
