Working with User Objects

User objects are used to send commands to the server. There are few different user objects:

• User and its variants in different sizes: UserMini, UserMicro
• UserImage, with a custom image
• UserList, with a list of user objects

Commands can be dealt with from Java or JavaScript in the events environment.

Every user object has a name and a parameter, that are sent to the server, and a repeat mode. If this mode is enabled, the behaviour will change:

• No repeat mode - the command is sent on the mouse up or touch up events

• Repeat mode enabled - three types of commands are sent:
  • down: on mouse down or touch down events
  • repeat: if the button is still pressed, a repeat command is sent every second
  • up: on mouse up or touch up events, for a short press (less than a second, so no repeat commands have been sent yet)
  • stop: on mouse up or touch up events, for a long press (more than a second, so at least a repeat command has been sent)

A UserList object has a list of items, each behaving like a user object.

While programming keep in mind that due to connection errors or user inputs (e.g. changing page) communication could be interrupted, so in the case of a user object with repeat mode enabled, the final command (up or stop) could be lost

Example

In this example we're going to use three user buttons to control a dimmer:

• on/off: no repeat, switches the dimmer on and off
• +: repeat mode, while pressed will increase the dimmer's value
• -: repeat mode, while pressed will decrease the dimmer's value
