DropDownList value selected by default?

[gespinha]

Hi there,

I've got the following DropDownList, but it gets rendered with no options selected. How can I make ''one" the default option for this element?

var w, layout;


layout = "dialog {  \
    dropdown: DropDownList { \
        size: [100,20] \
        properties: { \
            items: ['one','two','three'] \
        } \
    } \
}";


w = new Window(layout);
w.show();

Thanks

You just have to set the selection, example.

var w, layout;  
layout = "dialog {  \
    dropdown: DropDownList { \
        size: [100,20] \
        properties: { \
            items: ['one','two','three'] \
        } \
    } \
}";
w = new Window(layout);
w.dropdown.selection=0;
w.show();

Thanks, that worked

Btw, how do I return the value that is selected?

For example, I change the dropdown to 'three' and I want it to return to me the number of the selected option.

There are various ways here is one way to show the value when it is changed.

var w, layout;  
layout = "dialog {  \
    dropdown: DropDownList { \
        size: [100,20] \
        properties: { \
            items: ['one','two','three'] \
        } \
    } \
}";
w = new Window(layout);
w.dropdown.selection=0;
w.dropdown.onChange= function(){
    alert(w.dropdown.selection.text);
}
w.show();

The drop down list will show either the text or a number. with processing the result from a dropdownlist, you want to make sure you specify what you want or you will run into issues. To get the number of the selection you would werite:

alert(parseInt(w.dropdown.selection))

You need to default one. I your case 0, 1 or 2.  I don't know Photoshop ScriptUI only steal other UI example and modify for my application.   Here how a made font select-able note I set dd1 selection to 1 dd1 could also be change by remembering the previous run  and changing dd1 prior to displaying the dialog.

    dlg.msgPnl.grp6a =dlg.msgPnl.add('group');

    dlg.msgPnl.grp6a.orientation='row';

    dlg.msgPnl.grp6a.alignment='fill';

    dlg.msgPnl.grp6a.st1 = dlg.msgPnl.grp6a.add('statictext',undefined,'Font');

    fontlist = new Array();

        for (var i=0,len=app.fonts.length;i

        fontlist =  app.fonts.name;

        }

  dlg.msgPnl.grp6a.dd1 = dlg.msgPnl.grp6a.add('dropdownlist',undefined,fontlist);

  dlg.msgPnl.grp6a.dd1.selection=1;
