Tooltip

The tooltip is part of the Gameface custom components suite. As most of the components in this suite it uses slots to allow dynamic content.

Installation

npm i coherent-gameface-tooltip

Usage with UMD:

  • import the tooltip component:
<script src="./node_modules/coherent-gameface-tooltip/dist/tooltip.production.min.js"></script>
  • add the tooltip component to your html:
<gameface-tooltip target=".container">
    <div slot="message">Hello!</div>
</gameface-tooltip>

Usage with JavaScript:

If you wish to import the Tooltip using JavaScript you can remove the script tag and import it like this:

import { Tooltip } from 'coherent-gameface-tooltip';

or simply

import 'coherent-gameface-tooltip';

Note that this approach requires a module bundler like Webpack or Rollup to resolve the modules from the node_modules folder.

Specifying the content

Use the message slot to specify the message of the tooltip.

Full list of the available attributes can be found here.

<gameface-tooltip target=".container" on="mouseenter" off="mouseleave" position="left">
    <div slot="message">Message on left</div>
</gameface-tooltip>

You can also put more complex content like interactive controls such as buttons:

<gameface-tooltip id="tutorial" target=".container" on="mouseenter" position="top" off="click">
    <div slot="message">
        <div class="msg-container">
            <div class="title">Wellcome!</div>
            <div class="text">
                Hello, this is your first tutorial.
                Click the next button to continue.
            </div>
            <div class="button">Next</div>
        </div>
    </div>
</gameface-tooltip>

You can add more flexibility using JavaScript. In the above example the tooltip will be closed on click anywhere inside it. If you wish to close it only if the customer clicks for the example on the Next button you can manually attach a listener and call the hide method of the tooltip:

document.querySelector('.button').addEventListener('click', (e) => {
    document.querySelector('#tutorial').hide();
});

Add the Styles

<link rel="stylesheet" href="coherent-gameface-components-theme.css">
<link rel="stylesheet" href="style.css">

To overwrite the default styles, simply create new rules for the class names that you wish to change and include them after the default styles.

You can put any custom styles inline or use class names and add an external file.

How to use

Usually a tooltip is displayed as a result of an action performed on another element. For example, you need to show a tooltip with more data when you hover on an item in the inventory. To specify the trigger element use the target attribute. Its value is a query string used to get the element. Refer to the table below for the full list of attributes.

Setting a message

To set or change the tooltip message, use the setMessage method.

When the async attribute is present in <gameface-tooltip>, a callback that returns a Promise must be provided to the setMessage method. Async mode use case is shown in the demo page.
