Description:

qtjsonschemaform 1.0.0

qt-jsonschema-form
A tool to generate Qt forms from JSON Schemas.
Features

Error messages from JSONSchema validation (see jsonschema).
Widgets for file selection, colour picking, date-time selection (and more).
Per-field widget customisation is provided by an additional ui-schema (inspired by https://github.com/mozilla-services/react-jsonschema-form).

Unsupported validators
Currently this tool does not support anyOf or oneOf directives. The reason for this is simply that these validators have different semantics depending upon the context in which they are found. Primitive support could be added with meta-widgets for type schemas.
Additionally, the $ref keyword is not supported. This will be fixed, but is waiting on some proposed upstream changes in jsonschema
Example
import sys
from json import dumps

from qtpy import QtWidgets

from qt_jsonschema_form import WidgetBuilder

if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)

builder = WidgetBuilder()

schema = {
"type": "object",
"title": "Number fields and widgets",
"properties": {
"schema_path": {
"title": "Schema path",
"type": "string"
},
"integerRangeSteps": {
"title": "Integer range (by 10)",
"type": "integer",
"minimum": 55,
"maximum": 100,
"multipleOf": 10
},
"event": {
"type": "string",
"format": "date"
},
"sky_colour": {
"type": "string"
},
"names": {
"type": "array",
"items": [
{
"type": "string",
"pattern": "[a-zA-Z\-'\s]+",
"enum": [
"Jack", "Jill"
]
},
{
"type": "string",
"pattern": "[a-zA-Z\-'\s]+",
"enum": [
"Alice", "Bob"
]
},
],
"additionalItems": {
"type": "number"
},
}
}
}

ui_schema = {
"schema_path": {
"ui:widget": "filepath"
},
"sky_colour": {
"ui:widget": "colour"
}

}
form = builder.create_form(schema, ui_schema)
form.widget.state = {
"schema_path": "some_file.py",
"integerRangeSteps": 60,
"sky_colour": "#8f5902",
"names": [
"Jack",
"Bob"
]
}
form.show()
form.widget.on_changed.connect(lambda d: print(dumps(d, indent=4)))

app.exec_()

Notes
This package uses QtPy as an abstraction layer for PyQt5/PySide2/PyQt6/PySide6. One of those libraries must also be installed in order to function.
