Properties
| Name | Description | Reflects | Type | Default |

accesskey

Accesskey provides a hint for generating a keyboard shortcut for the current element. The attribute value must consist of a single printable character. |

align

CSS Class. This class is applied to the outside, on the web component itself. Due to how WebComponents work, this might not change anything inside the component. |
|
string
|
- |
data

Set the dataset from a CSV |
string
|
- | |
deferredProperties
|
Any attribute that refers to row content cannot be resolved immediately, but some like booleans cannot stay a string because it’s a boolean attribute. We store them for later, and parse when they’re fully in their row. If you are creating a widget that can go in a nextmatch row, and it has boolean attributes that can change for each row, add those attributes into deferredProperties | - | - | |
disabled
|
Defines whether this widget is visibly disabled. The widget is still visible, but clearly cannot be interacted with. Widgets disabled in the template will not return a value to the application code, even if re-enabled via javascript before submitting. To allow a disabled widget to be re-enabled and return a value, disable via javascript in the app’s et2_ready() instead of an attribute in the template file. |
|
boolean
|
false
|
dom_id
|
Get the actual DOM ID, which has been prefixed to make sure it’s unique. |
string

Application entry ID |
|
- | - |
hidden
|
The widget is not visible. As far as the user is concerned, the widget does not exist. Widgets hidden with an attribute in the template may not be created in the DOM, and will not return a value. Widgets can be hidden after creation, and they may return a value if hidden this way. |
|
boolean
|
- |
id
|
Get the ID of the widget |
string
|
- | |
label
|
The label of the widget This is usually displayed in some way. It’s also important for accessability. This is defined in the parent somewhere, and re-defining it causes labels to disappear |
string

Methods
| Name | Description | Arguments |
|---|---|---|
checkCreateNamespace()
|
Checks whether a namespace exists for this element in the content array. If yes, an own perspective of the content array is created. If not, the parent content manager is used. Constructor attributes are passed in case a child needs to make decisions | - |
clone()
|
Creates a copy of this widget. |
_parent: et2_widget
|
createElementFromNode()
|
Create a et2_widget from an XML node. First the type and attributes are read from the node. Then the readonly & modifications arrays are checked for changes specific to the loaded data. Then the appropriate constructor is called. After the constructor returns, the widget has a chance to further initialize itself from the XML node when the widget’s loadFromXML() method is called with the node. |
_node: , _name:
|
get_links()
|
Starts the request for link list to the server Called internally to fetch the list. May be called externally to trigger a refresh if a link is added. |
not_saved_links: LinkInfo[], offset:
|
getArrayMgr()
|
Returns the array manager object for the given part |
managed_array_type: string
|
getArrayMgrs()
|
Returns an associative array containing the top-most array managers. |
_mgrs: object
|
getChildren()
|
Get child widgets Use |
- |
getInstanceManager()
|
Returns the instance manager | - |
getPath()
|
Returns the path into the data array. By default, array manager takes care of this, but some extensions need to override this | - |
getRoot()
|
Returns the base widget Usually this is the same as getInstanceManager().widgetContainer | - |
loadFromXML()
|
Loads the widget tree from an XML node |
_node:
|
loadingFinished()
|
Needed for legacy compatability. |
promises: Promise[]
|
parseXMLAttrs()
|
The parseXMLAttrs function takes an XML DOM attributes object and adds the given attributes to the _target associative array. This function also parses the legacyOptions. N.B. This is only used for legacy widgets. WebComponents use transformAttributes() and do their own handling of attributes. |
_attrsObj: , _target: object, _proto: et2_widget
|
set_label()
|
NOT the setter, since we cannot add to the DOM before connectedCallback() TODO: This is not best practice. Should just set property, DOM modification should be done in render https://lit-element.polymer-project.org/guide/templates#design-a-performant-template |
value: string
|
set_value()
|
Set the value of the list Value can be: - String: CSV list of entries in either app:ID or just ID if
application is set. - Object: {to_app:
|
_value: string | { to_app : string, to_id : string } | LinkInfo[]
|
setArrayMgr()
|
Sets the array manager for the given part |
_part: string, _mgr: object
|
setArrayMgrs()
|
Sets all array manager objects - this function can be used to set the root array managers of the container object. |
_mgrs: object
|
setInstanceManager()
|
Set the instance manager Normally this is not needed as it’s set on the top-level container, and we just return that reference |
manager: etemplate2
|
_addLinks()
|
Render a list of links inside the list These get put inside the shadow dom rather than slotted |
links: LinkInfo[]
|
_delete_link()
|
Delete a link |
link: LinkInfo
|
_deleteButtonTemplate()
|
Build the delete button |
link: LinkInfo
|
_get_row_id()

Get an ID for a link |
link: LinkInfo
|
_handleChange()
|
Handle & pass on an internal change |
_event: ChangeEvent
|
_handleClick()
|
Click handler calling custom handler set via onclick attribute to this.onclick |
_ev: MouseEvent
|
_handleLinkToChange()
|
We listen to LinkTo widgets so we can update |
_ev:
|
_linkTemplate()
|
Render one link These elements are slotted and are found in the light DOM (use this.querySelector(…) to find them) |
link:
|
_loadingTemplate()
|
Render that we’re waiting for data | - |
_rowTemplate()
|
Render the row for one link. This is just the structure and slot, actual row contents are done in _linkTemplate. These rows are found in the shadowRoot. Use this.shadowRoot.querySelector(…) to find them. |
link:
|
_set_label()
|
Do some fancy stuff on the label, splitting it up if there’s a %s in it Normally called from updated(), the “normal” setter stuff has already been run before this is called. We only override our special cases (%s) because the normal label has been set by the parent |
