/**

> Create and control scollbar widgets.

* **This class is a JS wrapper around Qt's [QScrollBar class](https://doc.qt.io/qt-5/qscrollbar.html)**

A `QScrollBar` provides ability to add and manipulate native scrollbar widgets.

### Example

```javascript
import { QScrollBar } from "@vixen-js/core";

const scrollbar = new QScrollBar();
```
 */
export class QScrollBar extends QAbstractSlider<QScrollBarSignals> {
  constructor(arg?: QWidget<QWidgetSignals> | NativeElement) {
    let native: NativeElement;
    if (checkIfNativeElement(arg)) {
      native = arg as NativeElement;
    } else if (arg != null) {
      const parent = arg as QWidget;
      native = new addon.QScrollBar(parent.native);
    } else {
      native = new addon.QScrollBar();
    }
    super(native);
  }
}
wrapperCache.registerWrapper("QScrollBarWrap", QScrollBar);

export type QScrollBarSignals = QAbstractSliderSignals;
