Scroll problem

###usecontainer = {true} Need to be placed in ScrolView and add a callback method oncursorPosition to handle scroll bar positioning, refer to Examples this.scrollRef.current.scrollTo({y: scrollY - 30, animated: true});

`RichEditor`

The editor component. Simply place this component in your view hierarchy to receive a fully functional Rich text Editor.

RichEditor takes the following optional props:

placeholder

Wrap the editor content placeholder
initialContentHTML

HTML that will be rendered in the content section on load.
initialFocus
Boolean value to Initial content request focus. The default value is false.
disabled
Boolean value to disable editor. The default value is false.
enterKeyHint
String value to set return key type - returnKeyType
editorInitializedCallback

A function that will be called when the editor has been initialized.
editorStyle

Styling for container or for Rich Editor more dark or light settings. Object containing the following options:
- backgroundColor: Editor background color
- color: Editor text color
- caretColor cursor/selection color
- placeholderColor: Editor placeholder text color
- contentCSSText: editor content css text（initial valid）
- cssText: editor global css text（initial valid）
onChange Callback after editor data modification
onHeightChange Callback after height change

onMessage Callback outside postMessage internal type processing

<img src="" onclick="_.sendEvent('ImgClick')" contenteditable="false"/>

command Execute JS in the editor

 // $ = document
 this.richText.current?.commandDOM('$.execCommand('insertHTML', false, "<br/>")');

commandDOM Manipulate the DOM in the editor

 // $ = document.querySelector
 this.richText.current?.commandDOM(`$('#title').style.color='${color}'`);

useContainer A boolean value that determines if a View container is wrapped around the WebView. The default value is true. If you are using your own View to wrap this library around, set this value to false.
initialHeight useContainer is false by inline view of initial height
pasteAsPlainText A boolean value (false as default) that determines if the clipboard paste will keep its format or it will be done as plain text
onPaste Callback clipboard paste value
onKeyUp Callback Keyup event (Android 229 bug)
onKeyDown Callback Keydown event (Android 229 bug)
onInput Callback input value
onLink Callback link click
onFocus Callback editor focus
onBlur Callback editor blur
onCursorPosition Callback Enter the position of the cursor this.scrollRef.current.scrollTo({y: scrollY - 30, duration: 100, animated: true});

RichEditor also has methods that can be used on its ref to set:

setContentHTML(html: string)
insertImage(url: string, style?: string)
insertLink(title: string, url: string)
insertText(text: string)
insertHTML(html: string)
insertVideo(url: string, style?: string)
setContentFocusHandler(handler: Function)
blurContentEditor()
focusContentEditor()

This method registers a function that will get called whenver the cursor position changes or a change is made to the styling of the editor at the cursor's position., The callback will be called with an array of actions that are active at the cusor position, allowing a toolbar to respond to changes.

registerToolbar(listener: Function)

Example Usage:

<RichEditor
  ref={(r) => this.richtext = r}
  initialContentHTML={'Hello <b>World</b> <p>this is a new paragraph</p> <p>this is another new paragraph</p>'}
  editorInitializedCallback={() => this.onEditorInitialized()}
/>

`RichToolbar`

This is a Component that provides a toolbar for easily controlling an editor. It is designed to be used together with a RichEditor component.

The RichToolbar has one required property:

getEditor()

Which must provide a function that returns a ref to a RichEditor component.

This is because the ref is not created until after the first render, before which the toolbar is rendered. This means that any ref passed directly will inevitably be passed as undefined.

Other props supported by the RichToolbar component are:

actions

An array of actions to be provided by this toolbar. The default actions are:
- actions.insertImage
- actions.setBold
- actions.setItalic
- actions.insertBulletsList
- actions.insertOrderedList
- actions.insertLink
- actions.keyboard
- actions.setStrikethrough
- actions.setUnderline
- actions.removeFormat
- actions.insertVideo
- actions.checkboxList
- actions.undo
- actions.redo
onPressAddImage Functions called when the addImage actions are tapped.
onInsertLink Logic for what happens when you press on the add insert link button
disabled
Boolean value to disable editor. The default value is false.
iconTint
unselectedButtonStyle
selectedIconTint
selectedButtonStyle
disabledIconTint
disabledButtonStyle

These provide options for styling action buttons.
iconSize

Defines the size of the icon in pixels. Default is 50.
renderAction

Altenatively, you can provide a render function that will be used instead of the default, so you can fully control the tollbar design.
iconMap

RichTextToolbar comes with default icons for the default actions it renders. To override those, or to add icons for non-default actions, provide them in a dictionary to this prop.

Example Usage:

const richText = React.createRef() || useRef();
<RichToolbar editor={that.richText}/>

With Custom Action:

To define your own custom action:

Send your action name as string in the actions array.
Include an icon for it with the iconMap
Add a function prop with the same action name to be called on tap

<RichToolbar
    editor={that.richText}
	actions={[
		actions.setBold,
		actions.setItalic,
		actions.insertBulletsList,
		actions.insertOrderedList,
		actions.insertImage,
		'customAction',
	]}
	iconMap={{
		customAction: customIcon,
	}}
	customAction={this.handleCustomAction}
/>

import React from "react";
import { Text, Platform, KeyboardAvoidingView, SafeAreaView, ScrollView } from "react-native";
import {actions, RichEditor, RichToolbar} from "react-native-pell-rich-editor";

const TempScreen = () => {
	const richText = React.useRef();
	return (
        <SafeAreaView>
            <ScrollView>

                    <Text>Description:</Text>
                    <RichEditor

                            console.log("descriptionText:", descriptionText);
                        }}
                    />
                </KeyboardAvoidingView>
            </ScrollView>

            <RichToolbar
                editor={richText}
                actions={[ actions.setBold, actions.setItalic, actions.setUnderline, actions.heading1, ]}
                iconMap={{ [actions.heading1]: ({tintColor}) => (<Text style={[{color: tintColor}]}>H1</Text>), }}
            />
        </SafeAreaView>
    );
