# QtPromise::resolve
|
|
|
|
*Since: 0.5.0*
|
|
|
|
```cpp
|
|
QtPromise::resolve(T value) -> QPromise<R>
|
|
```
|
|
|
|
Similar to the [`QPromise<T>::resolve`](../qpromise/resolve.md) static method, creates a promise
|
|
resolved from a given `value` but without the extra typing:
|
|
|
|
```cpp
|
|
auto promise = QtPromise::resolve(); // QPromise<void>
|
|
auto promise = QtPromise::resolve(42); // QPromise<int>
|
|
auto promise = QtPromise::resolve(QString{"foo"}); // QPromise<QString>
|
|
```
|
|
|
|
This method also allows to convert `QFuture<T>` to `QPromise<T>`, delayed until the `QFuture` is
|
|
finished ([read more](../qtconcurrent.md#convert)).
