## Member Function Documentation

### `[explicit]` ElseIf::ElseIf(const QtTaskTree::ExecutableItem &condition)

Creates an alternative condition element with condition task to be used in conditional expression.

See also If.

### `[explicit]` template <typename Handler, std::enable_if_t<!std::is_base_of_v<ExecutableItem, std::decay_t<Handler>>, bool> = true> ElseIf::ElseIf(Handler &&handler)

A helper constructor accepting the synchronous handler to be executed when evaluating the initial condition by the running QTaskTree.

It's a shortcut for:

     ElseIf (QSyncTask(handler))

See QSyncTask for more information on what handler types are acceptable.

This is an overloaded function.
