Redirect variables
Redirect variables allow UI Objects to be linked dynamically to a source.
Redirect variables can be used in:
- any object's id
- I/O Server Objects, in server id and address parameters
- Button objects, in the address parameter
Syntax
Variables are defined with the following syntax:
[<variable name>]
E.g.
[myaddr]
Setting Values
Server UISets (from events or java) are used to set a redirect variable's value. Each redirect variable is a property of the "redirect" object. For example, a redirect variable called "myaddr" can be set to "70" with a UISet command on events:
UISET redirect.myaddr=70
Example: TempMini Object
In this example we will use a single TempMini object to display different sources. In hsyco.ini we have an ioServer with 3 zones.
ioServers = bmne500 ioServersType.bmne500 = MYHOME ioServersOptions.bmne500 = tempzones=1;2;3
In a project we place a TempMini and three User buttons. On the TempMini parameters, we use two redirect variables: mysid and myzone.
Each User button will have "changetemp" as name and "1", "2" or "3" respectively as param.
In events we declare:
function userCommand(session, userid, name, param) : { if (name == "changetemp") { uiSet("redirect", "mysid", "bmne500"); uiSet("redirect", "myzone", param); // address: "temp."+ myzone return "ok"; } }
Clicking on a button in the interface will execute the above callback, which sets the redirect variables' values and changes the source of the TempMini object accordingly.
Example: Button object
Similarly to the previous example, in a project we place a Button object with a redirect variable called myaddr. We also place two User buttons with name "changeaddr" and param "light.1" and "autom.1"
function userCommand(session, userid, name, param) : { if (name == "changeaddr") { uiSet("redirect", "myaddr", "dummy."+param); // dummy.light.1 } }
Once again clicking on a User button will cause the Button object to change its source, from a light to an autom.
