Gio.Task:completed
Description: Reference for property Gio.Task:completed

### Property

# Gio Task:completed

since: 2.44

#### Declaration

    property completed: gboolean [ read ]

#### Description

Whether the task has completed, meaning its callback (if set) has been invoked.

This can only happen after g_task_return_pointer(), `g_task_return_error()` or one of the other return functions have been called on the task. However, it is not guaranteed to happen immediately after those functions are called, as the task’s callback may need to be scheduled to run in a different thread.

That means it is not safe to use this property to track whether a return function has been called on the `GTask`. Callers must do that tracking themselves, typically by linking the lifetime of the `GTask` to the control flow of their code.

This property is guaranteed to change from `FALSE` to `TRUE` exactly once.

The `GObject::notify` signal for this change is emitted in the same main context as the task’s callback, immediately after that callback is invoked.
