This script block is used to "inject" embryo scripts to a given Edje theme and it functions in two modalities. When it's included inside a "program" block, the script will be executed every time the program is run, on the other hand, when included directly into a "group", "part" or "description" block, it will be executed once at load time, in the load order.

Programs define how your interface reacts to events. Programs can change the state of parts, react to events or trigger other events.

Hi,

Thanks! but how/where to trigger the scripts? Actually, I wanna the sample code. :)

Seems their's less edc programming related training material/guide on the help doc, also the tizen developer site.

I understand you prefer sample code instead of link but below link is very important.

Basically, program is run by event like "mouse,1,clicked". program block has "signal" and "source".
It means matched "signal" from "source" will trigger this program.
Program also has "action" that describes what will do when triggered. You can check actions from above link.

Sometimes action is not enough to do what you want. Then you can add script block instead of "action" of program.
Action uses embryo script. It is a small interpreter language.

You can see what functions are supported in "script" block from above links.

At the last, there is "script" block too in group block. It is a something like global scope area.
You can decleare some global variables, common function here.

I think above example is good for how script working.
