|
|
const { QProgressBar } = require("@nodegui/nodegui");

const progressBar = new QProgressBar();
|
|
```
|
|
|
|
### `new QProgressBar(parent?)`
|
|
|
|
- `parent` NodeWidget (_optional_). Any widget inheriting from NodeWidget can be passed as a parent. This will make this widget, the child of the parent widget.
