Split the root README.md in multiple Markdown files (in the `docs/` folder) to make easier reading, editing and extending the documentation. An online version is also available on netlify (https://qtpromise.netlify.com). Building it requires Node.js installed, then: - npm install -g gitbook-cli - gitbook install ./ - gitbook build . dist/docs

|
|
|
|
```
|
|
[static] QPromise<T>::reject(any reason) -> QPromise<T>
|
|
```
|
|
|
|
Creates a `QPromise<T>` that is rejected with the given `reason` of *whatever type*:
|
|
|
|
```cpp
|
|
QPromise<int> compute(const QString& type)
|
|
{
|
|
if (type == "foobar") {
|
|
return QPromise<int>::reject(QString("Unknown type: %1").arg(type));
|
|
}
|
|
|
|
return QPromise<int>([](const QPromiseResolve<int>& resolve) {
|
|
// {...}
|
|
});
|
|
}
|
|
```
