Rich text editor widget built on TinyMCE’s web component. Et2HtmlArea provides both rich text and plain text editing modes, integrates with EGroupware upload and language preferences, and exposes a small extension surface for editor-specific integrations such as custom toolbar buttons.

Examples

Toolbar Mode vs Preference

The mode property controls whether the editor uses one of the built-in toolbar presets or the user’s rte_toolbar preference.

• mode="simple" uses the simple preset
• mode="extended" uses the extended preset
• mode="advanced" uses the advanced preset
• mode="ascii" renders a plain textarea
• empty mode uses the rte_toolbar preference

If you want the editor to follow the user’s selected toolbar features, leave mode empty.

<et2-htmlarea label="Preference-driven toolbar"></et2-htmlarea>

      

      
    

If you need a fixed toolbar regardless of the user preference, set mode explicitly.

<et2-htmlarea label="Simple preset" mode="simple"></et2-htmlarea>

      

      
    

To hide the toolbar entirely, use noToolbar.

<et2-htmlarea label="No toolbar" noToolbar></et2-htmlarea>

      

      
    

Plain Text Mode

mode="ascii" renders a textarea instead of TinyMCE when editable, while preserving the same value, disabled, placeholder, focus, input, and change contracts as rich text mode.

<et2-htmlarea label="Plain text" mode="ascii" placeholder="Enter plain text"></et2-htmlarea>

      

      
    

Readonly Rendering

Readonly htmlareas render their value directly instead of initializing TinyMCE or a textarea. Rich text values are rendered as HTML; mode="ascii" values are rendered as literal text.

The lightweight et2-htmlarea_ro element is registered for readonly widget substitution, including nextmatch detached row updates.

File Selection And Uploads

Dropped and pasted images upload through EGroupware’s HTMLArea upload endpoint by default. Set image-upload to a VFS target widget id, content path, absolute path, or external URL when the upload destination needs to be explicit.

TinyMCE’s image, media, and file dialogs use the EGroupware VFS picker unless a custom filePickerCallback property is assigned.

Submit-time Formatting

Set apply-default-font when saved markup needs to carry the user’s preferred font and size inline, such as mail compose content that may be read by clients that strip editor CSS. The normalization happens during getValue(true), so it affects submitted rich-text content rather than the live editor appearance.

Custom Toolbar Buttons

Integrations can extend the TinyMCE toolbar without reaching through the legacy editor property. Add the toolbar item name with addToolbarItem(), then register the TinyMCE UI in registerEditorSetupHook(). TinyMCE documents the available toolbar button APIs in its custom toolbar buttons documentation.

The hook must be registered before TinyMCE finishes initializing. If an integration wraps or creates the htmlarea, call these methods as soon as the Et2HtmlArea instance is available.

import type {Et2HtmlArea} from "./Et2HtmlArea";

function addInsertGreetingButton(htmlarea : Et2HtmlArea)
{
	htmlarea.addToolbarItem("insertGreeting");
	htmlarea.registerEditorSetupHook("example-greeting-button", editor =>
	{
		editor.ui.registry.addButton("insertGreeting", {
			text: "Greeting",
			tooltip: "Insert greeting",
			onAction: () =>
			{
				editor.insertContent("<p>Hello</p>");
			}
		});
	});
}

      

      
    

Use a stable, integration-specific key for registerEditorSetupHook() so it can be replaced or removed later with unregisterEditorSetupHook(). The toolbar item name passed to addToolbarItem() must match the TinyMCE control name registered with editor.ui.registry.

Legacy Compatibility

The component keeps a small compatibility bridge while older integrations move off direct TinyMCE access:

• tinymce resolves with the TinyMCE editor array
• editor exposes the active TinyMCE editor
• file_picker_callback, images_upload_handler, valid_children, and toolbar_mode map to their modern camelCase properties

New integrations should prefer the component properties plus addToolbarItem() and registerEditorSetupHook() for editor UI extensions.
