Button

A button is a control that the user can click to perform an action.

Buttons can have icons, labels, and tooltips.

They can be styled with several attributes that change their color, shape, and look.

Attributes

Common

ID

Sets the object's ID.

The ID identifies the object and is used to reference it in UISet actions, allowing to change its attributes dynamically.

The ID is not unique, it can be shared among multiple objects to quickly change a common attribute.

IDs can't be changed with a UISet action, but they can have a Value Binding assigned to them. Value Bindings on IDs allow an object to be dinamically attached to a set of attribute values.

E.g. the following Value Binding switches the ID of the object between mybutton1 and mybutton2 based on the value of the UISet button.address:

Value binding: ="mybutton" + ui('button', 'address')

UISet: UISet('button', 'address', '1') switches the ID to mybutton1 UISet('button', 'address', '2') switches the ID to mybutton2

Position and Size

Position

The default value is: x0y0.

Attribute Values

Action

Action

Specifies the action performed when clicked/tapped.

Attribute Values

Value	Description
none	No action.
link	Changes page, shows a popup or opens a URL.
command	Sends a command to the server, with the specified name and parameter.
datapoint	Toggles a datapoint.
download	Fires a download file request that generates a specific command. A server-side userCommand script must intercept the command. If the content to be downloaded is an existing file, it should return a full pathname of the file to be downloaded, or a JSON object such as {"path":"pathname", "filename":"filename", "delete":true}, where path is the full pathname of the file to be downloaded and filename is the name of the file to be saved on the client. Delete is optional. When present and set to true, the file is deleted as soon as the download is initiated from the client. If the returned pathname is a valid and accessible file under the HSYCO main directory, the download will be initiated. It is also possible to generate the binary content to be downloaded directly from the userCommand script. In this case userCommand should return a JSON object like {"data":"&amp;<Base64-encoded data&amp;>", "filename":"filename"} where data is a Base64-encoded string of the binary data to be downloaded.
upload	Shows the upload file popup. A server-side uiSet (not a scope uiSet) must be executed to allow the upload and specify the upload path: uiSet("<object ID>", "path", "<upload path>") * name: the object ID * upload path: the path where the uploaded files are saved, relative to the HSYCO main directory When the upload is completed, a command is generated with: * name: the object ID * parameter: the uploaded file name, including the extension.
submit	Sends the values of all the fields within the button's container to the server. If not in a container, it submits all fields from the page. In overlay pages, if the button is not inside a container, it submits fields from the current page as well. Fields inside nested containers are included in the submissions. When submitting, if a field is not valid, it will be focused and the action will be canceled.
