## ScrollArea
Inherits from [QAbstractScrollArea](https://doc.qt.io/qtforpython/PySide6/QtWidgets/QAbstractScrollArea.html).

**Typo Alert** on the [Qt website docs for QScrollArea](https://doc.qt.io/qtforpython/PySide6/QtWidgets/QScrollArea.html) we see:
```python
imageLabel = QLabel()
image = QImage("happyguy.png")
imageLabel.setPixmap(QPixmap.fromImage(image))
scrollArea = QScrollArea
scrollArea.setBackgroundRole(QPalette.Dark)
scrollArea.setWidget(imageLabel)
```
and the `QScrollArea` should be `QScrollArea()`, i.e.
```python
imageLabel = QLabel()
image = QImage("happyguy.png")
imageLabel.setPixmap(QPixmap.fromImage(image))
scrollArea = QScrollArea() # <----------------------- parens() here
scrollArea.setBackgroundRole(QPalette.Dark)
scrollArea.setWidget(imageLabel)
```

### Example App
```python
#!/usr/bin/env python3
import sys
from PySide6.QtCore import *
from PySide6.QtGui import *
from PySide6.QtWidgets import *

app = QApplication(sys.argv)

win = QMainWindow()

imageLabel = QLabel()
image = QImage("a.png")
imageLabel.setPixmap(QPixmap.fromImage(image))
scrollArea = QScrollArea()
scrollArea.setBackgroundRole(QPalette.Dark)
scrollArea.setWidget(imageLabel)

win.setCentralWidget(scrollArea)
win.show()
exit(app.exec())
```
