Error loading external items in listbox

[smithcgl9043167]

Hello everyone once again! I'm working a dialog window containing a listbox that loads an external list.txt with icones.png, but today I've been getting an error message:

myList.items  .image = File ("~ / Desktop / Icons /" + imgs ); 

Guys can anyone test my script and check for the cause of the error.

My version of Photoshop:

Adobe Photoshop Version: 20.0.0 20180920.r.24 2018/09/20: 1193433 x64

var aFile = File ( "~/Desktop/ListIcons.txt" );
aFile.open('r');  var stringFromTextFile = aFile.read();  var imgs = stringFromTextFile.split("\n");
var w = new Window("dialog");
var myList = w.add("listbox");
for (var i = 0; i < imgs.length; i++) {
    myList.add("item");
    myList.items.image = File("~/Desktop/Icons/"+ imgs);
}
 myList.preferredSize = [120,190];
w.show();

Here lists and icons:

var aFile = File ( "~/Desktop/ListIcons.txt" );

aFile.open('r');  var stringFromTextFile = aFile.read();  var imgs = stringFromTextFile.split("\n");

var w = new Window("dialog");

var myList = w.add("listbox");

for (var i = 0; i < imgs.length; i++) {

    myList.add("item");

    if (imgs!="") myList.items.image = File("~/Desktop/Icons/"+ imgs);

}

myList.preferredSize = [120,190];

w.show();

How to put an event on.click at each icon?

[JJMack]

Its a list I would think you would not have an on click event for each list you woul gets an index number see which Icon was click on.  The you would perhaps change the dialog to show that  icon selected and show the dialog.  you could something different for each icon click on.  I don't know scriptUI  have only other users code that used pull-down list. These has a index value for the item being displayed in the pull down text list. I do not know actually how an image list works. Yours looks like the field is larger then a single icon more a scrollable list.

If it doesn't have an on.click event, what's the point of making a listbox with icons?

[smithcgl9043167]

I don't know if that answers your question geppettol66959005 , JJMack

I intend to use the function of each icon like this here:

 ///////////////////////////////
 //Event on each icon: In my case
myList.onChange = function(){  
     if(parseInt(myList.selection) == 0){alert("Item 1")}  
     if(parseInt(myList.selection) == 1){alert("Item 2")}  
     if(parseInt(myList.selection) == 2){alert("Item 3")}  
     myList.selection = null
 }

I don't understand why in Photoshop it looks unpleasant in the UI when the item is selected.

If we compare with other Adobe products, this looks more like a glitch. Have they noticed it yet?

I recommend deselecting the selection:

myList.selection = null

In every new version of photoshop there are new bugs

and worsen the development of ui script windows

in my opinion adobe no longer has an interest in ui script windows because it focuses on windows html extensions
