Vfs Name

<et2-vfs-name> | Et2VfsName

VFS file name, decoded from VFS path encoding. Shows the basename from row-bound data rather than the full path decodes the value on initially receiving it and encodes the value before submitting it Client side always has a decoded value and server side always sends and receives an encoded value Reading the row-bound value and opening the file live in VfsFileMixin, shared with the read-only variant below.

When to use it

et2-vfs-name is the editable file-name field in a filemanager row. It shows the basename of a VFS file while keeping the full path internally, so renaming a file does not require the template to carry the directory around separately.

For the read-only column, use et2-vfs-name_ro. To show or edit a whole path rather than one file’s name, use et2-vfs-path.

<et2-vfs-name id="vfsname-basic"></et2-vfs-name>
<script>
	customElements.whenDefined("et2-vfs-name").then(() =>
	{
		document.getElementById("vfsname-basic").value = {
			path: "/home/demo/Quarterly report.pdf",
			name: "Quarterly report.pdf",
			mime: "application/pdf"
		};
	});
</script>

Value

The widget is bound to a whole VFS row, not to a string:

<et2-vfs-name id="$row"></et2-vfs-name>

A row object supplies path (the full path) and name (the basename). The widget displays name and remembers the rest, because opening the file needs the path and the mime type. Given a plain string instead, it uses that string as the name and has no path to open.

Path encoding

VFS paths are encoded on the wire and decoded for display: the client side always holds a decoded value, the server always sends and receives an encoded one. The widget decodes the value once when it first receives it and encodes it again on submit, so a file called Report #3 (final).pdf survives a round trip without the template doing anything.

That conversion is the reason to use this widget rather than a plain et2-textbox for a file name.

Opening the file

Clicking a name opens the file with the standard handler for its mime type. If the server could not resolve the file at all - a symlink whose target was deleted, for instance - the widget says so rather than opening a link that would 404 into a blank tab.

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
autofocus Have browser focus this input on load. Overrides etemplate2.focusOnFirstInput(), use only once per page https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input#attributes
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.
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.
hasFeedbackFor Get a list of feedback types
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
label The label of the widget Legacy support for labels with %s that get wrapped around the widget Not the best way go with webComponents - shouldn’t modify their DOM like this
mask Mask the input to enforce format. The mask is enforced as the user types, preventing invalid input.
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
placeholder Placeholder text to show as a hint when the input is empty.
statustext Tooltip which is shown for this element on hover
styles WebComponent *
translate List of properties that get translated Done separately to not interfere with properties - if we re-define label property, labels go missing.
needed Compatibility for deprecated name “needed”
options Get property-values as object

SlInput⁠ (Shoelace)

Name Description
autocapitalize Controls whether and how text input is automatically capitalized as it is entered by the user.
autocomplete Specifies what permission the browser has to provide assistance in filling out form field values. Refer to this page on MDN⁠ for available values.
autocorrect Indicates whether the browser’s autocorrect feature is on or off.
clearable Adds a clear button when the input is not empty.
defaultValue The default value of the form control. Primarily used for resetting the form control.
enterkeyhint Used to customize the label or icon of the Enter key on virtual keyboards.
filled Draws a filled input.
form By default, form controls are associated with the nearest containing <form> element. This attribute allows you to place the form control outside of a form and associate it with the form that has this id. The form must be in the same document or shadow root for this to work.
helpText The input’s help text. If you need to display HTML, use the help-text slot instead.
inputmode Tells the browser what type of data will be entered by the user, allowing it to display the appropriate virtual keyboard on supportive devices.
max The input’s maximum value. Only applies to date and number input types.
maxlength The maximum length of input that will be considered valid.
min The input’s minimum value. Only applies to date and number input types.
minlength The minimum length of input that will be considered valid.
name The name of the input, submitted as a name/value pair with form data.
noSpinButtons Hides the browser’s built-in increment/decrement spin buttons for number inputs.
passwordToggle Adds a button to toggle the password’s visibility. Only applies to password types.
passwordVisible Determines whether or not the password is currently visible. Only applies to password input types.
pattern A regular expression pattern to validate input against.
pill Draws a pill-style input with rounded edges.
readonly Makes the input readonly.
required Makes the input a required field.
size The input’s size.
spellcheck Enables spell checking on the input.
step Specifies the granularity that the value must adhere to, or the special value any which means no stepping is implied, allowing any numeric value. Only applies to date and number input types.
type The type of input. Works the same as a native <input> element, but only a subset of types are supported. Defaults to text.
validationMessage Gets the validation message
validity Gets the validity state object
value The current value of the input, submitted as a name/value pair with form data.
valueAsDate Gets or sets the current value as a Date object. Returns null if the value can’t be converted. This will use the native <input type="{{type}}"> implementation and may result in an error.
valueAsNumber Gets or sets the current value as a number. Returns NaN if the value can’t be converted.

Textbox

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.
et2HandleBlur() If the value is unchanged, put any held validation messages back Named et2HandleBlur to avoid overwriting handleBlur() in Shoelace components
et2HandleFocus() When input receives focus, clear any validation errors. If the value is the same on blur, we’ll put them back The ones from the server (ManualMessage) can interfere with submitting. Named et2HandleFocus to avoid overwriting handleFocus() in Shoelace components
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
getInputNode() Get input to e.g. set aria-attributes
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
handleSlChange() Handle sl-change event from Shoelace components and dispatch a change event so anything listening for change events can react to it instead of having to listen for both sl-change and change.
isValid() Used by etemplate2 to determine if we can submit or not
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
submit() Encode the basename back to VFS path encoding before submitting.
validate() Massively simplified validate, as compared to what ValidatorMixin gives us, since ValidatorMixin extends FormControlMixin which breaks SlSelect’s render() We take all validators for the widget, and if there’s a value (or field is required) we check the value with each validator. For array values we check each element with each validator. If the value does not pass the validator, we collect the message and display feedback to the user. We handle validation errors from the server with ManualMessages, which always “fail”. If the value is empty, we only validate if the field is required.
_handleClick() Click handler calling custom handler set via onclick attribute to this.onclick
_oldChange() Change handler calling custom handler set via onchange attribute
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
