# QSearchableTreeWidget
`QSearchableTreeWidget` combines a
[`QTreeWidget`](https://doc.qt.io/qt-6/qtreewidget.html) and a `QLineEdit` for showing a mapping that can be searched by key.
This is intended to be used with a read-only mapping and be conveniently created
using `QSearchableTreeWidget.fromData(data)`. If the mapping changes, the
easiest way to update this is by calling `setData`.
```python
from qtpy.QtWidgets import QApplication
from superqt import QSearchableTreeWidget
app = QApplication([])
data = {
"none": None,
"str": "test",
"int": 42,
"list": [2, 3, 5],
"dict": {
"float": 0.5,
"tuple": (22, 99),
"bool": False,
},
}
tree = QSearchableTreeWidget.fromData(data)
tree.show()
app.exec_()
```
{{ show_widget() }}
{{ show_members('superqt.QSearchableTreeWidget') }}
