[!CAUTION]

本项目还处在开发阶段，API 接口可能随时发生变化，敬请谅解。

This project is still in development. The API may change at any time, so please bear with us.

Overview

class-widgets-sdk provides the essential base classes, development tools (like scaffolding and packaging), and complete type hints for creating plugins for Class Widgets 2.

This package provides the core SDK for development and must be installed in your plugin's environment. Plugins are executed within the Class Widgets 2 main application.

Installation

pip install class-widgets-sdk

Getting Started

1. Create a new plugin

Use the included CLI tool to generate a new plugin project structure:

cw-plugin-init com.example.myplugin

2. Install dependencies

Navigate to your new plugin directory and install the SDK in editable mode:

cd com.example.myplugin
pip install -e .

3. Usage (Base Class & Types)

The SDK provides the base class CW2Plugin and models for configuration, giving you full IDE autocompletion and static analysis support.

from ClassWidgets.SDK import CW2Plugin, ConfigBaseModel, PluginAPI

class MyConfig(ConfigBaseModel):
    enabled: bool = True
    text: str = "hEIlo, WoRId"

class MyPlugin(CW2Plugin):
    
    def __init__(self, api: PluginAPI):
        super().__init__(api)
        self.config = MyConfig()
    
    def on_load(self):
        self.api.config.register_plugin_model(self.pid, self.config)
        # Your IDE will provide full autocompletion here
        self.api.widgets.register(
            widget_id="com.example.mywidget",
            name="My Widget",
            qml_path="path/to/mywidget.qml"
        )

4. Package

Use the included CLI tool to build and package your plugin into a distributable .cwplugin or .zip file:

cw-plugin-pack

Tools

The SDK includes powerful command-line tools for plugin development and distribution:

Command	Description
cw-plugin-init	Generate a new plugin project scaffold.
cw-plugin-pack	Build and package the plugin into a distributable .cwplugin or .zip file.

cw-plugin-init

Initialize a new Class Widgets plugin project with an interactive setup wizard.

Usage:

# Create plugin in current directory (interactive)
cw-plugin-init

# Create plugin in specific directory
cw-plugin-init my-plugin

# Force overwrite existing files
cw-plugin-init my-plugin --force

Flow:

1. Select location (current dir or new folder)
2. Enter plugin metadata (name, author, ID, etc.)
3. Confirm and generate files

cw-plugin-pack

Build and package the plugin into a distributable .cwplugin or .zip file.

# Package current directory (default: .cwplugin)
cw-plugin-pack

# Specify format (.cwplugin or .zip)
cw-plugin-pack --format zip

# Specify output path
cw-plugin-pack -o ./dist/my-plugin.cwplugin

# Package specific directory
cw-plugin-pack ./my-plugin

Format

• .cwplugin - Recommended plugin format
• .zip - Standard archive format

How It Works

1. Development: You install this SDK package to get base classes, type hints, autocompletion, and static type checking (with mypy/pyright) in your IDE.
2. Runtime: When your plugin is loaded by the Class Widgets 2 main application, your CW2Plugin subclass is instantiated and executed.

[!IMPORTANT]

• This package is the Development Kit for your plugin. Plugins must be tested within the Class Widgets 2 main application.
• The import path for the SDK is ClassWidgets.SDK.
