@blockly/disable-top-blocks Built on Blockly

A Blockly plugin that shows the 'disable' context menu option only on non-orphan blocks. This is useful in conjunction with the Blockly.Events.disableOrphans event handler (which you must set up yourself).

Installation

Yarn

yarn add @blockly/disable-top-blocks

npm

npm install @blockly/disable-top-blocks --save

Usage

import * as Blockly from 'blockly';
import {DisableTopBlocks} from '@blockly/disable-top-blocks';

// Inject Blockly.
const workspace = Blockly.inject('blocklyDiv', {};

// Add the disableOrphans event handler. This is not done automatically by
// the plugin and should be handled by your application.
workspace.addChangeListener(Blockly.Events.disableOrphans);

// The plugin must be initialized before it has any effect.
const disableTopBlocksPlugin = new DisableTopBlocks();
disableTopBlocksPlugin.init();

API

  • init initializes the plugin and modifies the behavior of the 'disable' context menu item.
  • dispose restores the original behavior of the context menu. This is never required to be called, but can be if you want to programmatically disable the effects of the plugin.
