<et2-lavatar> | Et2LAvatar

Overview

Avatars are used to represent a person or profile. LAvatar has a coloured background.

LAvatar extends Avatar by adding fname and lname, and a coloured background. The background color is based on the fname and lname, not random. 

<et2-lavatar></et2-lavatar>

Examples

Name

If you don’t have an image to use, you can fname and lname to show initials. Setting fname or lname will also set the tooltip. LAvatar interferes with the initials attribute. 

<et2-lavatar initials="EG"></et2-lavatar>
<et2-lavatar fname="Test" lname="User"></et2-lavatar>

Contact ID

If you have only the ID for the profile, set contactId and LAvatar will ask the server for everything. If you set lname and fname the letter avatar will be shown until the server responds. 

<et2-lavatar contactid="contact:6"></et2-lavatar>
<et2-lavatar fname="Test" lname="User" contactid="contact:6" loading="lazy"></et2-lavatar>

See Avatar for more examples which will also work for LAvatar

Inherited properties (29)

Avatar

Name Description
accesskey Accesskey provides a hint for generating a keyboard shortcut for the current element. The attribute value must consist of a single printable character.
actions Set Actions on the widget Each action is defined as an object: move: { type: “drop”, acceptedTypes: “mail”, icon: “move”, caption: “Move to” onExecute: javascript:mail_move” } This will turn the widget into a drop target for “mail” drag types. When “mail” drag types are dropped, the global function mail_move(egwAction action, egwActionObject sender) will be called. The ID of the dragged “mail” will be in sender.id, some information about the sender will be in sender.context. The etemplate2 widget involved can typically be found in action.parent.data.widget, so your handler can operate in the widget context easily. The location varies depending on your action though. It might be action.parent.parent.data.widget To customise how the actions are handled for a particular widget, override _link_actions(). It handles the more widget-specific parts.
align Used by Et2Box to determine alignment. Allowed values are left, right
class 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.
contactId Function to set contactId contactId could be in one of these formats: ‘number’, will be considered as contact_id ‘contact:number’, similar to above ‘account:number’, will be considered as account id ‘email:’, will be considered as email address
data Set the dataset from a CSV
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.
dom_id Get the actual DOM ID, which has been prefixed to make sure it’s unique.
editable Make avatar widget editable to be able to crop profile picture or upload a new photo
full Take every column of a layout, the same as span="all". Boolean rather than a bare marker so it can be driven from content the way the rest of the template can - full="@is_wide" resolves through the array manager like any other boolean attribute. That does mean it needs a value: write full="true", since an empty full="" resolves to false and removes the attribute again. Reflects for the same reason grow does.
grow How much of a layout’s leftover space this widget should take. Only means anything inside a container that has a layout (see Et2LayoutController): a bare grow or grow="1" takes an equal share of whatever the non-growing children left over, grow="2" takes twice what a grow="1" sibling does. It has to reflect. The layout stylesheet matches the [grow] attribute - CSS cannot see a property - and transformAttributes() only calls setAttribute() for an attribute the element already carries or a property declared as reflecting. Widgets built from a .xet are created with document.createElement() and handed their attributes as an object, so they carry none at that point: without this declaration grow="1" lands as an inert JS property and nothing in the layout ever matches it.
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.
id Get the ID of the widget
image Deliberately NOT reflected. For a contactId we resolve the URL asynchronously (cachedQueue() in the contactId setter, since only the server knows whether a contact has a photo), so it lands after this widget has already rendered once. Reflecting it wrote that late answer back into the host’s attributes - and Et2Datagrid renders a row by handing rowElement.outerHTML to lit’s unsafeHTML(), which replaces the whole row node whenever that string differs from last time. So every avatar that resolved an image tore its entire row down and rebuilt it, re-running every widget constructor in it, purely because one attribute appeared after the fact. Nothing reads the attribute (no :host([image]) rule, here or in Shoelace’s own avatar styles), and attribute -> property still works for templates that set image=”…” - only the property -> attribute direction is dropped.
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
noLang Disable any translations for the widget
parentId Parent is different than what is specified in the template / hierarchy. Widget ID of another node to insert this node into instead of the normal location
shape The shape of the avatar circle | square | rounded
size Explicitly specify the avatar size. Better to set the –size CSS variable in app.css, since it allows inheritance and overriding
span How many of a layout’s columns this widget should take. span="all" is every column wherever the widget landed, span="end" / span="*" is from its own column to the end of its line. Only means anything inside a container that has a layout, and only for the column layouts - stack gives every child the full width anyway. The same name is also read straight off the XML node by the legacy <grid> widget, for the unrelated job of counting table cells to merge; that path never looks at the widget, so declaring it here does not disturb it. Reflecting it does mean a legacy grid’s span="all" cells now carry the attribute too, which matches nothing outside a layout. Reflects for the same reason grow does.

Avatar

Name Description
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.
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.
delButtonClickHandler() click handler to handel click on delete button
editButtonClickHandler() click handler to handle click on edit button
getArrayMgr() Returns the array manager object for the given part
getArrayMgrs() Returns an associative array containing the top-most array managers.
getChildren() Get child widgets Use .children to get web component children
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
loadingFinished() Needed for legacy compatability.
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.
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
setArrayMgr() Sets the array manager for the given part
setArrayMgrs() Sets all array manager objects - this function can be used to set the root array managers of the container 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
uploadAvatar_onFinish() Function runs after upload in avatar dialog is finished and it tries to update image and cropper container.
_handleClick() Click handler calling custom handler set via onclick attribute to this.onclick
destroy() et2_widget compatability
set_class() Set the widget class
set_disabled() Wrapper on this.disabled because legacy had it.
set_statustext() supports legacy set_statustext
