JSX in TabletopPlayground

before:

const image = new ImageWidget();
image.setTintColor([1, 1, 1, 0.75]);
image.setUrl("http://somewhere.com/image.png");

const element = new UIElement();
element.widget = image;

refObject.addUI(element);

after:

const element = new UIElement();
element.widget = render(<image url={"http://somewhere.com/image.png"} color={[1, 1, 1, 0.75]} />);
refObject.addUI(element);

Setting up the JSX transformer.

For now, you'll need to use Typescript, and I'll assume that you're familiar enough with the basics of typescript to know things like what your tsconfig.json file is. If someone wants to make something that'll work with esbuild or what not, I welcome it.

You can also use yarn create ttpg-package --template tsx to get a new workspace with jsx-int-tpg set up already.

changes to tsconfig.json

Add the "jsx" and "jsxFactory" fields to compilerOptions, and be sure to include "tsx" files to your tsc config. Files that use JSX need to have the file extension of "tsx".

    {
        "compilerOptions" {
            "jsx": "react",
            "jsxFactory": "jsxInTTPG",
            "jsxFragmentFactory": "jsxFrag",
            /* ... other compilerOptions ... */
        },
        "include": ["./src/**/*.tsx", /* other includes */]
    },

additionally, you'll need to add this import at the top of any file that uses JSX

import { jsxInTTPG } from "jsx-in-ttpg";

adding JSX to a UIElement or ScreenUIElement or a vanilla Widget

use the provided render function to ensure a JSX tag is a Widget. The top-level JSX tag must be a vanilla widget (or a string or array string, since jsxInTTPG will wrap a lone string in a <text> widget automagically). This could also be a custom component, so long as any nested components resolve to a structure with a top-level widget.

import { render, jsxInTTPG } from "jsx-in-ttpg";

const ui = new UIElement();
/* do stuff to set up ui element */
ui.widget = render(<text>Hello World</text>);
refObject.addUI(ui);

in instances where you need to set a new widget, or add a child, or if you want to mix-n-match JSX with vanilla TTPG elements, you can make use of the render() function in the same way:

const layoutBox = new LayoutBox();

layoutBox.setChild(render(<text>some text</text>));

Fragments

a custom component should always return a single JSXNode (or a primitive, null, etc, etc). If it turns out that you need to return multiple elements, wrap the returned elements in a fragment <>{...}</>. You will need to import {jsxFrag} from 'jsx-in-ttpg' to do so

import { render, jsxInTTPG, jsxFrag } from "jsx-in-ttpg";

const MyComponent = () => {
    return (
        <>
            <horizontalbox>
                <text>Hello</text>
                <text>World</text>
            </horizontalbox>
            <horizontalbox>
                <richtext>Some fancy [b]bolded[/b] text</richtext>
            </horizontalbox>
        </>
    );
};

const ui = new UIElement();

ui.widget = render(
    <layout>
        <verticalbox>
            <MyComponent />
        </verticalbox>
    </layout>
);

refObject.addUI(ui);

Syntax

Every Tabletop Playground widget is resprestented in a JSX intrinsic element with certain attributes that function as function calls or property setters for that widget.

  • Canvas: <canvas>
  • ImageWidget: <image>
  • ImageButton: <imagebutton>
  • ContentButton: <contentbutton>
  • Border: <border>
  • HorizontalBox: <horizontalbox>
  • VerticalBox: <verticalbox>
  • LayoutBox: <layout>
  • Text: <text>
  • Button: <button>
  • CheckBox: <checkbox>
  • MultilineTextBox: <textarea>
  • ProgressBar: <progressbar>
  • RichText: <richtext>
  • SelectionBox: <select>
  • Slider: <slider>
  • TextBox: <input>

Attributes

several function calls, event handlers, or properties of TTPG widgets are available as attributes on the JSX element.

Note that boolean-type attributes don't require you to put the actual true/false value to have that value be "true" - for example <button disabled>Some Text</button> is equivilent to <button disabled={true}>Some Text</button>. (this is why certain properties are kind of the "inverse" of what you find in vanilla TTPG widget syntax, such as "disabled" vs "setEnabled" and "hidden" vs "setVisible")

Common Attributes

  • disabled - optional boolean - equivilent to "setEnabled(!disabled)"
  • hidden - optional boolean - equivilent to "setVisible(!hidden)";
  • ref - optional RefObject<T> where T is the widget class being used - more on refs later.

ImageWidget

<image onLoad={() => {}} color={[1, 1, 1, 1]} card={Card} url={"http://..."} src={"someimage.jpg"} package={"..."} />

  • src - string: Equivilent to calling imageWidget.setImage(src)

  • srcPackage - string: Equivilent to calling imageWidget.setImage(src, srcPackage) - you must provide the src attribute for the srcPackage attribute to have any effect.

  • url - string: Equivilent to calling imagewidget.setUrl(...) - mutually exclusive with src and srcPackage as well as card.

  • card - Card: Equivilent to calling imageWidget.setSourceCard(...) - mutually exclusive with src and srcPackage as well as url.

  • onLoad - (image: ImageWidget, filename: string, packageId: string) => void: Equivilent to calling imagewidget.onImageLoaded.add(...).

  • color - [number, number, number, number] or Color: Equivilent to calling imagewidget.setTintColor(...).

  • width - number: Equivilent to calling imagewidget.setWidth(...).

  • height - number: Equivilent to calling imagewidget.setHeight(...).

  • <image> takes no children

ImageButton

<imagebutton onLoad={() => {}} color={[1, 1, 1, 1]} card={Card} url={"http://..."} src={"someimage.jpg"} package={"..."} onClick={() => {}} />

  • onClick: Equivilent of imageButton.onClicked.add(...)

  • src - string: Equivilent to calling imageWidget.setImage(src)

  • srcPackage - string: Equivilent to calling imageWidget.setImage(src, srcPackage) - you must provide the src attribute for the srcPackage attribute to have any effect.

  • url - string: Equivilent to calling imagewidget.setUrl(...) - mutually exclusive with src and srcPackage as well as card.

  • card - Card: Equivilent to calling imageWidget.setSourceCard(...) - mutually exclusive with src and srcPackage as well as url.

  • onLoad - (image: ImageWidget, filename: string, packageId: string) => void: Equivilent to calling imagewidget.onImageLoaded.add(...).

  • color - [number, number, number, number] or Color: Equivilent to calling imagewidget.setTintColor(...).

  • width - number: Equivilent to calling imagewidget.setWidth(...).

  • height - number: Equivilent to calling imagewidget.setHeight(...).

  • <imagebutton> takes no children

Border

<border ref={borderRef} color={[1, 0, 0, 1]}>
    <text>"Hello, world!"</text>
</border>

  • color - [number, number, number, number] or Color: Equivalent to calling border.setColor(...).

  • <border> can take strings or a single widget as children.

Canvas

The canvas has no additional attributes. however, canvases take an atypical child function. You can have more than one. This is so you can set the x, y, width, and height inline.

<canvas>
    {canvasChild({ x: 0, y: 0, width: 100, height: 100 }, <button>SomeText</button>)}
    {canvasChild({ x: 200, y: 0, width: 100, height: 100 }, <button>Some Other Text</button>)}
</canvas>
  • <canvas> can take multiple canvasChild calls as children. the second argument of canvasChild can be a string or a single widget.

LayoutBox

<layout halign={HorizontalAlignment.Center} valign={VerticalAlignment.Middle} padding={{ left: 10, right: 10, top: 5, bottom: 5 }}>
    <image src="avatar.jpg" />
</layout>

  • valign - VerticalAlignment: Equivalent to calling layoutBox.setVerticalAlignment(...).

  • halign - HorizontalAlignment: Equivalent to calling layoutBox.setHorizontalAlignment(...).

  • padding - number | { left?: number, right?: number, top?: number, bottom?: number }: Equivalent to calling layoutBox.setPadding(...) if a single number is used, it is applied to all four directions.

  • maxHeight - number: Equivalent to calling layoutBox.setMaximumHeight(...).

  • minHeight - number: Equivalent to calling layoutBox.setMinimumHeight(...).

  • height - number: Equivalent to calling layoutBox.setOverrideHeight(...).

  • maxWidth - number: Equivalent to calling layoutBox.setMaximumWidth(...).

  • minWidth - number: Equivalent to calling layoutBox.setMinimumWidth(...).

  • width - number: Equivalent to calling layoutBox.setOverrideWidth(...).

  • <layout> can take strings or a single widget as children.

VerticalBox

VerticalBox (as well as the HorizontalBox) can take a special function child, much like Canvas. Unlike Canvas, however, it's not required. the first parameter of boxChild is the "weight" and the second is the Widget (or string) that will be that child.

<verticalbox gap={10} halign={HorizontalAlignment.Left} valign={VerticalAlignment.Middle}>
    <text>"Hello!"</text>
    {boxChild(3, <button>Some Button</button>)}
    <image src="image1.jpg" />
</verticalbox>

  • gap - number: Equivalent to calling verticalBox.setChildDistance(...).

  • valign - VerticalAlignment: Equivalent to calling verticalBox.setVerticalAlignment(...).

  • halign - HorizontalAlignment: Equivalent to calling verticalBox.setHorizontalAlignment(...).

  • <verticalbox> can take strings, any number of widgets, or the special {boxChild(1, <...>)} function.

HorizontalBox

<horizontalbox ref={hboxRef} disabled={false} hidden={false} gap={10} halign={HorizontalAlignment.Left} valign={VerticalAlignment.Middle}>
    <image src="image1.jpg" />
    <text>"Hello!"</text>
</horizontalbox>

  • gap - number: Equivalent to calling verticalBox.setChildDistance(...).

  • valign - VerticalAlignment: Equivalent to calling verticalBox.setVerticalAlignment(...).

  • halign - HorizontalAlignment: Equivalent to calling verticalBox.setHorizontalAlignment(...).

Extendable Component-esque functions

You can make your own "components" that you can re-use throughout your code. I've re-used the same convention that React/Typescript uses: built-in widgets are all lowercase. Custom components must start with an Uppercase letter. Note the below: "RobPanel" vs "verticalbox".

// RobPanel can be used anywhere I want this style of panel - with some forward thinking, it can be made more abstract and re-usable, if one wanted to.

const RobPanel = (props: { children?: SingleNode; title: TextNode; onClose?: () => void }) => {
    return (
        <border color={[0, 0, 0, 1]}>
            <verticalbox>
                <border color={[0.125, 0.125, 0.125, 1]}>
                    <horizontalbox valign={VerticalAlignment.Center}>
                        {boxChild(1, <text justify={TextJustification.Center}>{props.title}</text>)}
                        <button onClick={props.onClose}>Close</button>
                    </horizontalbox>
                </border>
                {boxChild(1, props.children)}
            </verticalbox>
        </border>
    );
};

const element = new UIElement();
element.widget = render(<RobPanel title={"My Model"}>Hi There</RobPanel>);

refObject.addUI(element);

Using Refs

JSX is only used to instantiate a widget. It does not take into account any changes you make to the widget inline through some state. For those who are familiar with JSX in the context of React or simiar, this will be jarring, no doubt. In order to programmatically access and alter a deeply nested widget, you can pass in a ref object into the ref attribute of an element.

To do this, call the provided useRef() function to generate a ref object. Once the widget has been instantiated, you can access the Widget directly using refObj.current. see the below.

if the widget hasn't been instantiated yet, the ref.current value will be null.

There is a trap here, however. It's important that if you are done with a certain widget, you clear the ref, otherwise the widget may not get properly garbage collected. To do this, call refObj.clear(). additionally, you can pass the same refObject to a new element to recyle it if you're no need a reference to the previous widget.

Example with useRef

const imageRef = useRef<ImageWidget>();
const layoutRef = useRef<LayoutBox>();

const checkRef = () => {
    console.log(imageRef.current);
    if (imageRef.current) {
        console.log(imageRef.current.getTintColor());
    }
};

element.widget = render(
    <border color={[0, 0, 0, 1]}>
        <verticalbox gap={10}>
            <layout maxWidth={240}>
                <image ref={imageRef} url={"https://raw.githubusercontent.com/RobMayer/TTSLibrary/master/ads/offworldcolonies_h.jpg"} />
            </layout>
            <horizontalbox>
                <button onClick={checkRef}>Check</button>
            </horizontalbox>
        </verticalbox>
    </border>
);

refObject.addUI(element);

you can also just keep a reference to the widget the old-fashioned way, too, but I find it easier to keep the widget in the right place in the hierarchy rather than scattering discreet widgets around the script.

const layoutRef = useRef<LayoutBox>();

const imageElement = render(<image url={"https://raw.githubusercontent.com/RobMayer/TTSLibrary/master/ads/offworldcolonies_h.jpg"} />);

const checkRef = () => {
    console.log(imageElement);
    console.log(imageElement.getTintColor());
};

element.widget = render(
    <border color={[0, 0, 0, 1]}>
        <verticalbox gap={10}>
            <layout maxWidth={240}>{imageElement}</layout>
            <horizontalbox>
                <button onClick={checkRef}>Check</button>
            </horizontalbox>
        </verticalbox>
    </border>
);

refObject.addUI(element);
