StyleContext.addProviderForScreen

void addProviderForScreen(gdk.screen.Screen screen, gtk.style_provider.StyleProvider provider, uint priority)

Adds a global style provider to screen, which will be used in style construction for all #GtkStyleContexts under screen.

GTK+ uses this to make styling information from #GtkSettings available.

If both priorities are the same, A #GtkStyleProvider

added through [gtk.style_context.StyleContext.addProvider] takes precedence over another added through this function.

`screen`	a #GdkScreen
`provider`	a #GtkStyleProvider
`priority`	the priority of the style provider. The lower it is, the earlier it will be used in the style construction. Typically this will be in the range between [gtk.types.STYLE_PROVIDER_PRIORITY_FALLBACK] and [gtk.types.STYLE_PROVIDER_PRIORITY_USER]
