A clickable image similar to the user object used to execute customized Java code or generate events for the EVENTS interpreter. Pressing this button, HSYCO calls the method:

userCommand(String name, String param)

in the user.class class. HSYCO also executes all actions associated to the event:

USER name=param

defined in EVENTS. For a tutorial on how to use this object see Working with User Objects. A long press will repeat the request every second.

For an object with a list of user commands, see UserList.


  • 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
  • name: name passed to the Java callback method and event in EVENTS
  • parameter: parameter passed to the Java callback method and event in EVENTS
  • label: the text label next to the image. It can contain HTML tags
  • css: the label's css attributes
  • repeat: if "enabled", the command will be repeat every second


(userimage[!<id>] <image's filename>; <position>; <width>; <height>; <name>; <parameter>; <label>; <css>; <repeat>)


(userimage!user1 myimage.png; r8c7; 100; 100; name; param; Label; (font-style:italic; top:-15px))
