The lacking use of smart pointers confuses me
Added by Alexander Theißen about 10 years ago
It is not clear to me when I am responsible for an object I allocated and when not.
The manual makes it clear that the application is responsible for destroying all widgets in it's view hierarchy.
But what about other pointers? I learned (from a crash) that the application destroys it's localized strings on destruction. But what about WCombinedLocalizedStrings. Does it destroy all it's WMessageResourceBundle on destruction?
What about other things? For example the WValidator on a WFormModel? Does it get destroyed when the form model destructs? Does the WTemplateFormView destroy it's model?
Without testing I have no clue. Is there some clear rule when I am responsible for destroying an object?

Hey,
The documentation will in general state what happens with ownership (if it doesn't, that's a bug).
As to your specific questions:
Ownership of the resolver is transferred.
If the validator has no ownership yet, the form model will take ownership.
WTemplateFormView does not take ownership of the model; in fact it's never assigned a model; it is not linked to a specific model.
