import UIPlugin from 'phaser3-rex-plugins/templates/ui/ui-plugin.js';
var config = {
    // ...
    plugins: {
        scene: [{
            key: 'rexUI',
            plugin: UIPlugin,
            mapping: 'rexUI'
        },
        // ...
        ]
    }
    // ...
};
var game = new Phaser.Game(config);

var label = scene.rexUI.add.titleLabel(config);

Import class¶

Install rex plugins from npm
```
npm i phaser3-rex-plugins

Import class

import { TitleLabel } from 'phaser3-rex-plugins/templates/ui/ui-components.js';

Add label object

var label = new TitleLabel(scene, config);
scene.add.existing(label);

Layout children¶

Arrange position of all elements.

label.layout();

Get element¶

Get element

Background game object

var background = label.getElement('background');

InnerSizer
```
var innerSizer = label.getElement('innerSizer');
```
- In mode 0, innerSizer contains title, separator, and text.
- In mode 1, innerSizer contains icon, text, and action.

Background game object inside innerSizer

var innerBackground = label.getElement('innerBackground');

Title game object

var textObject = label.getElement('title');

Separator game object

var textObject = label.getElement('separator');

Icon game object
```
var icon = label.getElement('icon');
```

Text game object

var textObject = label.getElement('text');

Action icon game object

var action = label.getElement('action');

Get by name

var gameObject = label.getElement('#' + name);
// var gameObject = label.getElement('#' + name, recursive);

or

var gameObject = label.getByName(name);
// var gameObject = label.getByName(name, recursive);

recursive : Set true to search all children recursively.

Title¶

Get title string
```
var s = label.title;
```
Set title string
```
label.setTitle(s);
```
or
```
label.title = s;
```

Text¶

Get text string
```
var s = label.text;
```
Set text string
```
label.setText(s);
```
or
```
label.text = s;
```

Icon texture¶

Set texture

label.setTexture(key);
// label.setTexture(key, frame);

Set texture via texture object

label.setTexture(texture);
// label.setTexture(texture, frame);

Get texture, frame.

var texture = label.texture;
var frame = label.frame;

Get texture key, frame name.

var textureKey = label.texture.key;
var frameName = label.frame.name;

Reset display content¶

label.resetDisplayContent({
    title: '',
    text: '',

    icon: undefined, 
    iconFrame: undefined,
    iconSize: undefined,

    action: undefined, 
    actionFrame: undefined,
    actionSize: undefined,

})

or

label.resetDisplayContent(text);

title : Set title's text string.
text : Set text string.
icon, iconFrame
- A string : Set texture of icon game object.
- undefined, or null : Hide icon game object.
- true : Show icon game object without change its texture.

action, actionFrame
- A string : Set texture of icon game object.
- undefined, or null : Hide action game object.
- true : Show action game object without change its texture.
actionSize : Set display size of action game object.

Run label.layout() after this method, to layout children again.
