Note  For a description and a complete list of UI Objects, see UI Objects.

A clickable image from the www/img directory. You can add an optional label text next to the image, and define several optional CSS attributes to control the text’s format and position. The “top” CSS attribute is used to move the text from its default position. If top is not defined, the text will be located just below the image. If defined, you can specify a positive or negative offset, in pixels. The zero offset position is at the top corner of the image; a positive offset moves the text down, a negative offset moves the text up.

Parameters

  • id: the object's ID, used by UISets
  • image: image filename
  • position: the object's position. Use the pixels or rows and columns coordinates format
  • size: the image's width and height
  • page: the name of the destination page associated to the button. It is possible to specify an absolute or relative URL in the page parameter. The tag will work as an <A HREF> tag, loading the new page. If the URL is prefixed with "!", the page will open in a new tab or window.. If the loaded page is an HSYCO menu, the back link will show up in the menu page, to reload the referrer page. It is also possible to use the special keywords "$__urlkey;" and "$__query;" that will be replace with the URLKey and URL query string (if present, including the leading "?" character). You can also set this parameter to "back", "forward" or "logout". "back" moves back to the previous page in the pages navigation history, and can also close the current pop-up. "forward" moves forward in the pages navigation history. "logout" closes the session and reverts to the login page
  • label: the image's label
  • css: the label's css attributes
Image files are searched inside the www/<project's name>/img directory first, then inside the www/img directory.
If the filename is set with a UISet, it's possible to load an image from the web by entering the URL, or a path relative to www/<skin's name>/pic by specifying /pic/ followed by the filename

e.g.: line(0,100,20,50,blue);line(50,50,70,70,'255,10,150');

legacymode true To use with the draw attribute. Enables a compatibility mode that allows draw instructions on old browsers. It works by sending instructions to the HSYCO server that generates an image. For this reason it's slower.

<url> A url starting with http:, https:, ftp: or / (for a relative url). When the button is clicked, the browser will navigate to the specified url (e.g. "http://www.apple.com")
