Photoshop Dropdown List Question:

I am trying to add a dropdown list whereby the user can change the units to either INCHES or CM

listStrings = ["INCHES", "CM"];
myDlg = new Window('dialog', 'Drop-down List');
myDlg.orientation = 'column';
myDlg.alignment = 'right';
//add drop-down
myDlg.DDgroup = myDlg.add('group');
myDlg.DDgroup.orientation = 'row';
myDlg.DDgroup.add('statictext', undefined, "Unit Measurements");
myDlg.DDgroup.DD = myDlg.DDgroup.add('dropdownlist', undefined, undefined, {items:listStrings})
myDlg.DDgroup.DD.selection = 4;
myDlg.closeBtn = myDlg.add('button', undefined, 'OK');
result = myDlg.show();
app.preferences.rulerUnits = Units.myDlg.DDgroup.DD.selection
// add button functions
myDlg.closeBtn.onClick = function() {
 this.parent.close();
}

it works to some degree but Photoshop seems to hang and become unresponsive after pressing the button. Ideally I would prefer the units to change from the dropdown list selection rather than having to press the button.

Any advice please

See if this is good for you.

listStrings = ["PIXEL","INCHES", "CM"];  
myDlg = new Window('dialog', 'Drop-down List');  
myDlg.orientation = 'column';  
myDlg.alignment = 'right';  
  
//add drop-down  
myDlg.DDgroup = myDlg.add('group');  
myDlg.DDgroup.orientation = 'row';  
myDlg.DDgroup.add('statictext', undefined, "Unit Measurements");  
myDlg.DDgroup.DD = myDlg.DDgroup.add('dropdownlist',undefined,listStrings); 
myDlg.DDgroup.DD.selection = 0;
myDlg.closeBtn = myDlg.add('button', undefined, 'OK');  
  
myDlg.DDgroup.DD.onChange = function(){ 
    switch(parseInt(myDlg.DDgroup.DD.selection)){ 
        case 0:  
          var originalUnit = preferences.rulerUnits;
    preferences.rulerUnits =Units.PIXELS;
          app.refresh();
            break; 
        case 1:
           var originalUnit = preferences.rulerUnits;
    preferences.rulerUnits = Units.INCHES;
      app.refresh();
            break;            
        case 2: 
                  var originalUnit = preferences.rulerUnits;
    preferences.rulerUnits = Units.CM;
      app.refresh();
            break;         
        }     
  } 
  
  result = myDlg.show();  
  
// add button functions  
myDlg.closeBtn.onClick = function() {  
 this.parent.close();  
}
