Wanna select multiple folders in the open dialog box, but it’s impossible, isn’t it?

[Kasyan Servetsky]

Hi forum,

The File and Folder objects have openDlg() method. The former has also the multiSelect parameter, the latter doesn’t.

I wish I could also have it for the Folder so I could ctrl/shift select multiple folders instead of picking up a folder and processing all its subfolders.

Maybe I’m missing something obvious or there’s an workaround to make such a dialog box.

Hi Kasyan,

I am a bit confused by you assumption. As far as I can see in the DOM, although a Folder object can bederivated from a generic File object, the openDialog and by extension openDlg are Files instance methods only. The Folder instance on the contrary has a selectDialog() and selectDlg() method.

I tried just in case to call openDialog and openDlg on both the Folder class and Folder instance, and it throwed an error quite unsurprisingly.

So I guess the only workaround would be to build your own folder selection window.

FWIW,

Loïc

As suggested, a possible approach :

Folder.prototype.selectMultipleDialog = function (prompt,multiselect){
  var w = new Window('dialog','MultipleSelectDialog'),
  st,
  ls,
  btnGp,
    koBtn,
    okBtn,
    folderFilter = function(f){
        return (f instanceof Folder)
    },
    u,
    folders = this.getFiles(folderFilter),
    getFolderNames = function(foldersObjectArray){
        var n = foldersObjectArray.length,
        namesArray = [];
        while ( n--){
            namesArray = decodeURI(foldersObjectArray.name);
        }
        return namesArray;
    },
    folderListItems = getFolderNames(folders),
    n = 0;



    st = w.add('statictext',u,prompt);
    ls = w.add('listbox',undefined, folderListItems, {multiselect:multiselect} );

    btnGp = w.add('group');

    koBtn = btnGp.add('button',u,'Cancel');
    okBtn = btnGp.add('button',u,'Select');


    koBtn.onClick = function(){
  w.close(0);
  }


  okBtn.onClick = function(){
  w.close(1);
  }

    ls.onChange = function() {
        okBtn.enabled = ls.selection!==null;
    }

    w.preferredSize.width = 450;
    w.alignChildren = ["fill","top"];
    ls.preferredSize.height = 200;
    btnGp.alignChildren = ["right","top"];


  okBtn.enabled = false;

    if ( w.show()==1 ){
  if ( ls.selection instanceof Array ) {
  n = ls.selection.length;
            while ( n-- ) folders[ls.selection.index].execute();
  }
  else {
  folders[ls.selection.index].execute();
  }
  }
}


var fo = Folder.desktop;
fo.selectMultipleDialog("test", true)

Hi, 

I am trying to get theis to work in Photoshop CC, the dialogue box opens but the listbox isn't populating, if anyone else could take a  quick look and see if they can get the code to work it would be appreciated?

Thanks

Anthony

When the forums were moved a few years ago, some legacy code got corrupted, usually single-characters in side brackets (ie. folder[n] = name became folder = name). I fixed it below. 

Folder.prototype.selectMultipleDialog = function (prompt,multiselect){
    var w = new Window('dialog','MultipleSelectDialog'),
        st,
        ls,
        btnGp,
        koBtn,
        okBtn,
    
    folderFilter = function(f){
        return (f instanceof Folder)
    },
    u,
    folders = this.getFiles(folderFilter),
    getFolderNames = function(foldersObjectArray){
        var n = foldersObjectArray.length,
        namesArray = [];
        while ( n--){
        namesArray[n] = decodeURI(foldersObjectArray[n].name);
    }
    return namesArray;
    },
    
    folderListItems = getFolderNames(folders),
        n = 0;
        st = w.add('statictext',u,prompt);
        ls = w.add('listbox',undefined, folderListItems, {multiselect:multiselect} );
        btnGp = w.add('group');
        koBtn = btnGp.add('button',u,'Cancel');
        okBtn = btnGp.add('button',u,'Select');
        koBtn.onClick = function(){
            w.close(0);
        }
        okBtn.onClick = function(){
        w.close(1);
    }
    
    ls.onChange = function() {
        okBtn.enabled = ls.selection!==null;
    }
    
    w.preferredSize.width = 450;
    w.alignChildren = ["fill","top"];
    ls.preferredSize.height = 200;
    btnGp.alignChildren = ["right","top"];
    okBtn.enabled = false;
    if ( w.show()==1 ){
        if ( ls.selection instanceof Array ) {
        n = ls.selection.length;
        while ( n-- ) folders[n][ls.selection.index].execute();
    }
    else {
        folders[ls.selection.index].execute();
    }
    }
    }
    
    var fo = Folder.desktop;
    fo.selectMultipleDialog("test", true)
