Smartface MaterialTextBox Component

A marketplace component to overcome the quirks of MaterialTextBox to make it easier to use.

Installation

Execute the command on your scripts directory:

npm i @smartface/component-materialtextbox

Features

• Drop-down arrow and a function to invoked upon click
• Clear all functionality for both platforms instead of X button on iOS
• Show / Hide functionality for senstivie informations like passwords
• Trim extra whitespaces ( open at default )

Usage

Options object will be assigned directly onto UI.MaterialTextBox class. You can also use platform specific values under it,

function setMaterialTextBox() {
    const flEmail = this.flEmail;
    flEmail.options = { 
        hint: "Email Address",
        className: ".login" //Documented under theming section, a custom variable for multi theme
    };
    flEmail.clearAllEnabled = true;
    flEmail.showHideEnabled = true;
    flEmail.enableDropDown = true; // Use this if you ONLY want to have the icon.
    flEmail.onDropDownClick = (isInside) => {
        /** 
         * This tweaks normal textbox behavior, it executes this function instead of waiting for user input.
         * To re-enable normal behavior on runtime, define this property to 'undefined' or null
        */
    }
    flEmail.trim = false; // To disable trim functionality if needed.
}

Alternatively, you can create your own materialTextBox object and add it to the component at will. Example :

import MaterialTextBox from "@smartface/native/ui/materialtextbox";

function setMaterialTextBox() {
    const signInMaterialTextBox = new MaterialTextBox({
        hint: "Sign In",
        text: "[email protected]"
    });
    this.flEmail.initMaterialTextBox(signInMaterialTextBox); // Second parameter ( optional ) is className
    // To add a barebone materialTextBox, use addChild() method of contx.
    this.flEmail.addChild(signInMaterialTextBox, "materialTextBox", ".materialTextBox");
    this.signInMaterialTextBox = signInMaterialTextBox;
}

The latest materialTextBox instance you create will override the previous one.

Learn more about addChild at contxjs.

To access the materialTextBox itself, follow this behavior

    function onLoad() {
        this.setMaterialTextBox();
        this.flEmail.materialTextBox.onActionButtonPressed = () => {
            alert("Action button pressed");
            this.flEmail.materialTextBox.text = "[email protected]";
        };
    }

Remarks

All of the properties in materialTextBox will work. You can give platform specific value directly into the object.

IMPORTANT NOTE : Initializing FlMaterialTextBox on the constructor might cause unexpected errors and styles for materialTextBox will not be applied, because the component is not in the context. Make your implementation in onShow() or onLoad() methods on the page.

ADDITIONAL NOTE for adding to a library component : Use Object.defineProperties() or a function for your code and call it on onShow() or onLoad() methods of the parent page.

const FlMaterialTextBox = require("@smartface/materialtextbox");

function onLoad(superOnLoad) {
    superOnLoad();
    const page = this;
    const flEmail = new FlMaterialTextBox();
    page.layout.addChild(flEmail, "flSignIn", ".materialTextBox-wrapper");
    flEmail.options = { 
        hint: "Enter Email"
    };
}

Theming & Customization

The default theme implementation is under /themes/baseTheme/styles/default/materialTextBox.json file. DO NOT make changes on this file.

To change the themes as you like, simply create themes/${selectedTheme}/styles/default/materialTextBox.json with your changed styles. You can find best practices for theming under smartface documentations.

To use multiple themes across one project, simply add subclasses under .materialTextBox class and customize it as you like.

    ".materialTextBox": {
        ...,
        ".login": {
            "ellipsizeMode": "START",
        },
        "&-password": {
            "textAlignment": "MIDRIGHT" 
        }
    },

    flEmail.options = { 
        hint: "Email Address",
        className: ".login" //Will inherit default class themes 
    };
    flPassword.options = { 
        hint: "Email Address",
        className: "-password" //Will not inherit default class themes
    };

The className property will be appended directly into the class which materialTextBox will use.

    const class = `.materialTextBox${className}`;

Due to technical limitations, the height of wrapper and materialTextBox inside of it must be equal
