abouturi

A URL to information provided by the developer about this app.

autorefresh

Determines whether a basic or custom app should automatically refresh data (true) at a specific interval. This defaults to false. See also refreshinterval.

Custom apps must also implement a handler method for refreshes. See Enable User-Initiated or Automatic Refreshes for more information.

debug

Determines whether logged messages display in the console of browser developer tools when the app is run. This defaults to false.

Developers may set this flag to false in the App Specification or use this as an app parameter in the app URL.

height

The default height, in pixels, to render this app or auto. Defaults to auto.

This attribute is only used when the containing page for the app does not specify or control the dimension of the space where the app is rendered. For more information, see App Dimensions and Resizing.

hideheader

Determines whether the title bar displays for this app (false). Set to true to hide the title bar.

The title bar contains the app title and may also contain toolbar buttons based on configuration for the app. See Title Bars and Toolbar Buttons in Apps for more information.

hideinputs

Determines whether the input form, if any, for this app opens initially when the app opens (false). The input form may still be accessible to users in a toolbar button in the app title bar or through other user interface widgets provided by the container where the app is published.

This attribute defaults to false.

id

Unique identifier assigned by Presto when the app is created. This is read-only and cannot be changed.

name

The name for this app. Presto uses the app name to assign a unique identifier to the app. App names can contain characters from the character sets supported by the Presto Repository, numbers, spaces, tabs, line ends and these common symbols: _ ~ - * ' .

jsclass

The constructor function for the optional JavaScript class for this app. Apps are not required to define a Javascript class with a constructor unless the app should be initialized after the page is ready.

Initializing the app after the page is ready can ensure that specific properties or objects are available.

refreshinterval

How frequently, in seconds, a basic or custom app should automatically refresh data. This defaults to zero. If set to a number greater than zero, autorefresh is treated as true.

Custom apps must also implement a handler method for refreshes. See Enable User-Initiated or Automatic Refreshes for more information.

sandbox

Determines whether this app should be rendered in a secure mode (true). This is false by default.

In secure mode, the app runs inside an <iframe> to isolate the app from effects from other objects in the containing page and vice versa.

singleton

This is reserved for future use.

version

The version of this app. This is informational only.

width

The default width, in pixels, to render this app or auto. Defaults to auto.

This attribute is only used when the containing page for the app does not specify or control the dimension of the space where the app is rendered. For more information, see App Dimensions and Resizing.
