================================================
Breaking: #77137 - JavaScript API of RTE changed
================================================
See :issue:`77137`
Description
===========
Due to the migration of the RTE from ExtJS to Bootstrap and jQuery, some API methods have been changed or removed.
Impact
======
ExtJS-based plugins will throw JavaScript errors.
The following methods have been removed:
* `onContainerResize`
* `getWindowDimensions`
* `setTabPanelHeight`
* `syncHeight`
The following methods have been changed:
* `openContainerWindow`
* `buildButtonConfig`
Affected Installations
======================
All installations using custom RTE plugins are affected.
Migration
=========
The former `Ext.Window` objects are replaced by Bootstrap modals.
See the list below for a migration of the changed methods:
openContainerWindow
The third parameter `dimensions` which used to be an array has changed to `height`, containing an integer
buildButtonConfig
The method takes now two additional arguments: `active` and `severity`. The parameter `active` is a boolean
value and declares the button being either active or not. The parameter `severity` is an integer representing the
severity of the button. This should always represent the severity of the modal, use one of the severities defined in
:js:`TYPO3/CMS/Backend/Severity`.
