This project provides a Qt Widget library which allows editing of arbitrary Google Protobuf messages.
There are three widget types introduced:
BuiltInTypeWidget is a widget which allows editing any of the built-in protobuf plain types, such as string, enum, int, float, etc. The widget contains a label and some other widget (depending on the data-type) laid out horizontally. Optional fields have a checkbox as the label.
MessageTypeWidget is a widget which aggregates a vertically laid out collection of BuildInTypeWidgets or nested MessageTypeWidgets.
ProtobufEditor is an example widget of how the MessageTypeWidget would be used.
To create a widget for editing your own protobuf message, construct a MessageTypeWidget with a pointer to the Descriptor of your message. This is sufficient for the Widget to build the UI for editing your message. Then, call setMessage on the widget with a pointer to your message. As the data in the UI elements are updated, the protobuf message will be updated in realtime and a signal (messageUpdated) will be emitted. See protobufEditor.cpp for an example.
Contributions are encouraged. Things that are not yet supported:
- Map
- Repeated
- OneOf
Also, ideally I'd like to provide a way for the user to override widgets based on a specific field name, or an entire type.
