Syntax:

IR.AddListener(Event, Item-owner, Function, Item-executor);

Input parameters:

Event 
the event name or number available for the graphic item;

Item-owner

Function

the named or unnamed function containing commands for execution;

Item-executor
the link to the graphic item which will be controlled;

Output parameters:

Operation description:
As it is required to learn the name of the event owner, in this case Item- owner and Item-executor will be one and the same item.

Example:
Subscribe the function to the event of pressing on the graphic item named Item 1 on Page 1. The function will type the graphic item name

IR.AddListener(

    IR.EVENT_ITEM_PRESS, 
    IR.GetPage("Page 1").GetItem("Item 1"), 
    Item_Press, 
    IR.GetPage("Page 1").GetItem("Item 1")
);

function Item_Press(){

   IR.Log(this.Name);   
}

Unnamed function:

IR.AddListener(IR.EVENT_ITEM_PRESS, IR.GetPage("Page 1").GetItem("Item 1"), function(){

   IR.Log(this.Name);
   
}, IR.GetPage("Page 1").GetItem("Item 1"));

Subscription by identifiers:

IR.AddListener(IR.EVENT_ITEM_PRESS, IR.GetPage(2).GetItem(0), Item_Press, IR.GetPage(2).GetItem(0));

function Item_Press(){

   IR.Log(this.Name);   
}

Learn the Popup Status (Shown or Hidden)

// Announce the variable for storing the popup status 
var Popup_1_is_Showing = false; // false - hidden, true - shown
// Receive the link to the popup 
var Popup = IR.GetItem("Popup 1"); 

// Subscribe the unnamed function to the event of popup showing. Change the value of the status in the function to true
IR.AddListener (IR.EVENT_ITEM_SHOW, IR.GetPage("Popup 1"), function() {

       Popup_1_is_Showing = true;
});

// Subscribe the unnamed function to the event of popup hiding. Change the value of the status in the function to false
IR.AddListener (IR.EVENT_ITEM_HIDE, IR.GetPage("Popup 1"), function() {

      Popup_1_is_Showing = false;
});

// Announce the function to check the popup status 
function Popup_1_Action_of_Status () {

   if (Popup_1_is_Showing) {

       // Actions if it is shown 
   } else {

      // Actions if it is hidden 
   }
};

Assign Dynamic Images(Camera) to Items

Variant 1:
There is a preset dynamic image in the tab Project Gallery / Dinamic Images. The image has the name "Camera".

// Assigning the dynamic image to the Image property by the name 
IR.GetItem("Page 1").GetItem("Item 1").GetState(0).Image = "Camera";

Variant 2:
Assigning of a dynamic image by the URL link (at that it does not matter if there a preset dynamic image in the project or not).

// Assigning a dynamic image (video stream) to the Image property by th URL link
IR.GetItem("Page 1").GetItem("Item 1").GetState(0).Image = "http://admin:12345@192.168.0.1:80/link";

// You can assign images (not video) to the Image property the same way:
IR.GetItem("Page 1").GetItem("Item 1").GetState(0).Image = "https://images.google.com/images/nav_logo195.png";
