  # Demo Modules 005

  Accessible GUI-based simple canvas editor

- §

  Related files:

  - Canvas minimap module
  - Canvas scene editor module
  - DOM entity editor module - which has a related CSS file
  - Entity copy-paste module
  - Entity manipulation GUI module
  - Entity navigation module

  Run code

      import * as scrawl from '../source/scrawl.js';

      import { reportSpeed } from './utilities.js';

- §

  All the functionality required to set up this sort of editor is managed in the `canvas-scene-editor.js` module

      import { initializeCanvasSceneEditor } from './modules/canvas-scene-editor.js';

- §

  #### Scene setup

      const sceneCanvas = scrawl.library.canvas['scene-canvas'];

      sceneCanvas.set({
          label: 'A demonstration of a simple design system.',
          description: 'The entitys in this canvas can be positioned, sized, copied and styled using mouse UI and keyboard input.',
      });

- §

  #### Create the editor

      const {
      /* eslint-disable-next-line */
          killSceneEditor,
          sceneLayer,
          addControllerAttributes,
          setGuiControlChars,

      } = initializeCanvasSceneEditor({
          sceneCanvas,
          domEntityEditor: '#scene-canvas-dahsboard',
          sceneDimensions: 1000,
      }, scrawl);

- §

  #### Build initial scene

      const getRandomPosition = () => {

          const x = Math.floor(Math.random() * 800) + 100;
          const y = Math.floor(Math.random() * 800) + 100;

          return [x, y];
      }

- §

  Add some entitys that we want to control

      scrawl.makeBlock({

          name: 'block-entity-1',
          group: sceneLayer.name,
          start: getRandomPosition(),
          handle: ['center', 'center'],
          dimensions: [100, 50],
          fillStyle: 'blue',
          lineWidth: 3,
          strokeStyle: 'orange',
          method: 'fillThenDraw',

- §

  The entity’s hover, click and drag-drop functionality

          ...addControllerAttributes,

      }).clone({

          name: 'block-entity-2',
          start: getRandomPosition(),

      }).clone({

          name: 'block-entity-3',
          start: getRandomPosition(),

      }).clone({

          name: 'block-entity-4',
          start: getRandomPosition(),
      });

      scrawl.makeWheel({

          name: 'wheel-entity-1',
          group: sceneLayer.name,
          start: getRandomPosition(),
          handle: ['center', 'center'],
          radius: 50,
          includeCenter: true,
          fillStyle: 'green',
          lineWidth: 3,
          strokeStyle: 'orange',
          method: 'fillThenDraw',
          ...addControllerAttributes,

      }).clone({

          name: 'wheel-entity-2',
          start: getRandomPosition(),

      }).clone({

          name: 'wheel-entity-3',
          start: getRandomPosition(),

      }).clone({

          name: 'wheel-entity-4',
          start: getRandomPosition(),
      });

      scrawl.makePicture({

          name: 'picture-entity-1',
          group: sceneLayer.name,
          imageSource: 'img/iris.png',
          dimensions: [150, 150],
          start: getRandomPosition(),
          handle: ['center', 'center'],
          copyDimensions: ['100%', '100%'],
          copyStart: [0, 0],
          lineWidth: 4,
          strokeStyle: 'gold',
          method: 'drawThenFill',
          ...addControllerAttributes,

      }).clone({

          name: 'picture-entity-2',
          start: getRandomPosition(),
      });

      scrawl.makePhrase({

          name: 'phrase-entity-1',
          group: sceneLayer.name,
          text: 'Hello',
          font: 'serif',
          size: '40px',
          lineHeight: 0,
          start: getRandomPosition(),
          handle: ['center', 'center'],
          ...addControllerAttributes,

      }).clone({

          name: 'phrase-entity-2',
          start: getRandomPosition(),

      }).clone({

          name: 'phrase-entity-3',
          start: getRandomPosition(),

      }).clone({

          name: 'phrase-entity-4',
          start: getRandomPosition(),
      });

  #### User interaction

  Most interaction is handled in the modules; the only thing we need to do here is give users the opportunity to update their keyboard character choices for manipulating the GUI controls

      const button = document.querySelector('#update-keyboard-shortcuts-action');

      const buttonClickAction = () => {

          const keys = window.prompt('To change the keyboard settings to move, scale and rotate selected entitys, enter the desired characters (11 in total) in the order MOVE-DELTA, MOVE-UP, MOVE-LEFT, MOVE-DOWN, MOVE-RIGHT, SCALE-DELTA, SCALE-GROW, SCALE-SHRINK, ROTATE-DELTA, ROTATE-CLOCKWISE, ROTATE-ANTI-CLOCKWISE (with no spaces or separating commas etc, though the comma key can be used as a shortcut). Character case will be ignored.', 'QWASDBNMGJH');

          setGuiControlChars(keys);
      };

- §

  @ts-expect-error

      button.onclick = buttonClickAction;

- §

  #### Scene animation

  Function to display frames-per-second data, and other information relevant to the demo

      const report = reportSpeed('#reportmessage');

- §

  Create the Display cycle animation

      scrawl.makeRender({
          name: "demo-animation",
          afterShow: report,
      });

- §

  #### Development and testing

      console.log(scrawl.library);
