Function Documentation

InstallModelSanitizer()

UTIL_MODELS_API void LC::Util::InstallModelSanitizer

(

QAbstractItemModel &

model

)

Attaches a QAbstractItemModelTester to model for the rest of its lifetime.

The tester checks the model against the QAbstractItemModel invariants at the time of the call and after each of the model's change signals from then on.

Since the model tester checks invariants on installation time as well and calls the model's methods, call this only after the class has set up everything its QAbstractItemModel overrides read, (typically as the last statement of its constructor). If a class is designed to be derived from and its model-related methods overridden, never do this from a base class constructor.

Parameters

[in]

model

The model to check.
