How do I read ScriptUI checkbox values?

[Guest]

From the follow code, how do I read the Boolean of whether a box was checked or not? For each box that's checked, I would like to create a rectangle on the active doc filled with that color. I just can't figure out how to access the user's input. Or am I tackling this problem from the wrong direction?

myDlg = new Window('dialog', 'Add Pantone Swatches');
myDlg.orientation = 'column';
myDlg.alignment = 'right';

with(myDlg.add('group'))
{
    orientation = 'row';
    with(add('panel'))//First structure of Window is materialized
    {
        orientation = 'column';
        add('statictext', undefined, "Please select which swatches to use:");
        with(add('group'))
        {
            orientation = 'column';
            for(i=app.activeDocument.swatches.length-1; i !=0; i--){
                add('checkbox', undefined, String(app.activeDocument.swatches.name));
                }            
        }
    }
}
with(myDlg.add('group'))
{
    orientation = 'row';
    add('button', undefined, "OK", {name: 'ok'});//Ok and Cancel Buttons
    add('button', undefined, "Cancel",{name: 'cancel'});
 }

if(myDlg.show())
{
    if(app.documents.length == 0)
        app.documents.add(DocumentColorSpace.CMYK);
}

"checkbox" is not good choice for your purpose, you'd better use "listBox", the listBox selection items's index are what you need.

And you use too much "with" statement!

#target Illustrator
app.documents.length || app.documents.add(DocumentColorSpace.CMYK);

var doc =  app.activeDocument, sw = doc.swatches,
     myDlg = new Window('dialog', 'Add Pantone Swatches');
myDlg.orientation = 'column';
myDlg.alignment = 'right';
 
with(myDlg.add('panel'))//First structure of Window is materialized
{
     orientation = 'column';
     add('statictext', undefined, "Please select which swatches to use:");
     var swatchBox = add('listBox', undefined, sw, {multiselect: true});
}
with(myDlg.add('group'))
{
    orientation = 'row';
    add('button', undefined, "OK", /*{name: 'ok'}*/).onClick = drawRect;//Ok and Cancel Buttons
    add('button', undefined, "Cancel",{name: 'cancel'});
 }

function drawRect (){
     var items = swatchBox.selection, len = items.length, i = 0;
     for (; i < len; i ++){
          doc.pathItems.rectangle(0, i*100, 100, 100).fillColor = sw[items.index].color;
     }
     myDlg.close(0);
}

myDlg.show();

I agree, too much use of "with"

moluapple, listbox is empty, needs to be populated, right?.

But sw is an Array, and have converted to listItems for listBox, isn't it?

here's a sample of a way to check wich check boxes are checked

#target Illustrator

myDlg = new Window('dialog', 'Add Pantone Swatches');

myDlg.orientation = 'column';

myDlg.alignment = 'right';

var checkboxes = []; // added array to hold all check boxes

with(myDlg.add('group'))

{

    orientation = 'row';

    with(add('panel'))//First structure of Window is materialized

    {

        orientation = 'column';

        add('statictext', undefined, "Please select which swatches to use:");

        with(add('group'))

        {

            orientation = 'column';

            for(i=app.activeDocument.swatches.length-1; i >=0; i--){ // changed != with >=

                checkboxes = add('checkbox', undefined, String(app.activeDocument.swatches.name)); // assign all check boxes to a variable array

                }           

        }

    }

}

with(myDlg.add('group'))

{

    orientation = 'row';

    btnOk = add('button', undefined, "OK", {name: 'ok'});// assigned Ok button to a variable

    add('button', undefined, "Cancel",{name: 'cancel'});

}

// added a function to get the values of the checked check boxes

btnOk.onClick = function()

     {

          var msg = 'Checked Swatches are:\r';

          for (j=0; j<checkboxes.length-1;j++)

               {

                    if (checkboxes.value == true)

                         msg = msg + checkboxes.text + '\r';

               }

          alert(msg);

     }

if(myDlg.show())

{

    if(app.documents.length == 0)

        app.documents.add(DocumentColorSpace.CMYK);

}

Carlos, I've adapted this (post 3) to add some user options to a script. Everything works great except if the Cancel button is clicked the script still executes. How can I make the Cancel button stop everything? Thanks for your time.

Edit: Cancel that, the trick seems to be putting the commands inside the function that only executes if OK is clicked.

Edit 2: myDlg.close(); is super helpful at the end of the onClick function(). As usual, thanks a ton for all the content here. It's a lifesaver.

thanks for answering your own questions
