Workspace UI

Workspace is essential part of Polotno framework. It is the main React component that you are going to use to display the drawings and interact with them. You can change canvas and its content programmatically using Store API.

import { Workspace } from 'polotno/canvas/workspace';
import { createStore } from 'polotno/model/store';

const store = createStore({
  key: YOUR_API_KEY, // you can create it here: https://polotno.com/cabinet/
  // you can hide back-link on a paid license
  // but it will be good if you can keep it for Polotno project support
  showCredit: true,
});

const App = () => {
  return (
    <div style={{ height: '100vh' }}>
      <Workspace store={store} />
    </div>
  );
};

The Workspace will automatically take full width and height of its parent. So you don't have adjust its size manually. You can just setup the size of parent <div> with CSS.

Customize page controls

You can customize page controls of your <Workspace /> component. You can remove some buttons, add new one, etc. You are in total control on what else you want to see around page on the canvas.

Take a look into Page Name Demo to see controls component in action.

<Workspace
  store={store}
  components={{
    PageControls: ({ width, height, xPadding, yPadding }) => (
      <div
        style={{
          position: 'absolute',
          top: yPadding + 'px',
          left: xPadding + 'px',
        }}
      >
        My controls here...
      </div>
    ),
  }}
/>

Hide page controls

Optionally you can hide UI to add/remove/duplicate pages.

<Workspace store={store} components={{ PageControls: () => null }} />

Workspace styling

Optionally you can change some styles of the workspace.

<Workspace
  store={store}
  backgroundColor="grey"
  pageBorderColor="black" // border around page
  activePageBorderColor="red" // border around active page. It will be used only if you have several pages. Otherwise just pageBorderColor will be used
  bleedColor="rgba(255, 0, 0, 0.2)" // color of the bleed area, when it is toggled with `store.toggleBleed()`
/>

No pages UI

If your store has no pages, <Workspace /> component will show a simple UI with a button to create a new page. You can overwrite this UI with your own.

<Workspace
  store={store}
  components={{
    NoPages: ({ store }) => <div>The project has no pages...</div>,
  }}
/>

Overwrite keyboard handler

If you don't like default keyboard shortcuts, you can overwrite them with your own.

<Workspace
  store={store}
  onKeyDown={(e, store) => {
    if (e.key === 'Escape') {
      store.selectElements([]);
    }
  }}
/>
