==================================================

|
Deprecation: #100454 - Legacy tree implementations
|
|
==================================================
|
|
|
|
See :issue:`100454`
|
|
|
|
Description
|
|
===========
|
|
|
|
Due to many refactorings in TYPO3's tree implementations in the past versions,
|
|
many implementations and functionality of the legacy rendering :php:`\TYPO3\CMS\Backend\Tree\AbstractTreeView`
|
|
is not needed anymore.
|
|
|
|
The following PHP classes are not in use anymore and have been marked as deprecated:
|
|
|
|
* :php:`\TYPO3\CMS\Backend\Tree\View\BrowseTreeView`
|
|
* :php:`\TYPO3\CMS\Backend\Tree\View\ElementBrowserPageTreeView`
|
|
|
|
The base class is still available, but discouraged to be used or extended,
|
|
even though TYPO3 still uses this in a few places.
|
|
|
|
The following properties and methods within the base class
|
|
:php:`AbstractTreeView` have either been marked as deprecated or
|
|
declared as internal:
|
|
|
|
* :php:`AbstractTreeView->thisScript`
|
|
* :php:`AbstractTreeView->BE_USER`
|
|
* :php:`AbstractTreeView->clause`
|
|
* :php:`AbstractTreeView->title`
|
|
* :php:`AbstractTreeView->table`
|
|
* :php:`AbstractTreeView->parentField`
|
|
* :php:`AbstractTreeView->orderByFields`
|
|
* :php:`AbstractTreeView->fieldArray`
|
|
* :php:`AbstractTreeView->defaultList`
|
|
* :php:`AbstractTreeView->determineScriptUrl()`
|
|
* :php:`AbstractTreeView->getThisScript()`
|
|
* :php:`AbstractTreeView->PM_ATagWrap()`
|
|
* :php:`AbstractTreeView->addTagAttributes()`
|
|
* :php:`AbstractTreeView->getRootIcon()`
|
|
* :php:`AbstractTreeView->getIcon()`
|
|
* :php:`AbstractTreeView->getRootRecord()`
|
|
* :php:`AbstractTreeView->getTitleStr()`
|
|
* :php:`AbstractTreeView->getTitleAttrib()`
|
|
|
|
|
|
Impact
|
|
======
|
|
|
|
Instantiating the deprecated classes or calling the deprecated methods will
|
|
trigger a PHP deprecation warning, except for
|
|
:php:`AbstractTreeView->getThisScript()`, which is still used internally by
|
|
deprecated code.
|
|
|
|
The Extension Scanner will find those usages and additionally also reports
|
|
usages of the corresponding public properties of the :php:`AbstractTreeView`
|
|
class.
|
|
|
|
|
|
Affected installations
|
|
======================
|
|
|
|
TYPO3 installations with custom extensions using this functionality. This is
|
|
usually the case for old installations from TYPO3 v6 or TYPO3 v4 times.
|
|
|
|
|
|
Migration
|
|
=========
|
|
|
|
It is recommended to avoid generating the markup directly in PHP. Instead use
|
|
one of various other tree functionalities (for example, see PageTree implementations)
|
|
in PHP and render trees via web components or Fluid.
