This item can load any qml component, just like a Loader. Important difference, the component will only be loaded when the "when" property is satisfied (ie evaluates to true) in this way it's easy to have big (and memory expensive) parts of the user interface load only when a certain condition is satisfied. For instance the contents of the tabs of a TabBar can be loaded only when they become the current page.

Property Documentation

Item ConditionalLoader::item

The item instantiated from component, if any.

Definition at line 48 of file ConditionalLoader.qml.

variant ConditionalLoader::source

It can be a string with a path name of a qml file or a Component.

It's the component that will be loaded when "when" is true. If the component changes the old instantiated component will be deleted and the new one will be loaded instead.

Definition at line 43 of file ConditionalLoader.qml.

bool ConditionalLoader::when

Condition that tells when to load the declarative component.
