  EditText Listbox subitem

  Posted by Scott Mcgee on April 3, 2017 at 3:57 pm

  I have two columns, Column one is to reference my layer, Column two is to reference a value.

  My array will always sequentially go in order, but my value will always change. So I want to include to the expression below. That if I fill out var input = win.add (“edittext”);
  input.active = true;
  

  it will add it to column two if I hit add item.

  Then say I got the number wrong. I want it to be another value. If I highlight the row. Refill out var input = win.add (“edittext”);
  input.active = true;
  then hit insert.

  It will update it.

  I’ve seen scripts that just us insert via editText and scripts that use just arrays. I haven’t found an example that allows the two.

  var testArr = [];

  startGUI();
  function startGUI() {

  // Main Window
  var win = new Window( “palette”, “Test Listbox”, undefined, { resizeable:true } );
  win.orientation = “column”;
  win.alignChildren = [“fill”, “fill”];

  // Listbox Group
  var grpListbox = win.add(‘group’);
  grpListbox.alignChildren = [‘fill’, ‘fill’];

  var myListbox = addListBox (grpListbox, testArr);

  // add ListBox
  function addListBox(container, testArr) {
  var listbox = container.add(“listbox”, undefined, testArr,
  {
  numberOfColumns: 2,
  showHeaders: true,
  columnTitles: [‘Bar’, ‘Value’]
  });

  return listbox;
  }

  var input = win.add (“edittext”);
  input.active = true;
  var b = win.add (“button”, undefined, “Insert”, {name: “ok”});

  // BTN: Add Items To Array
  var addItem = win.add(“button”, undefined, “Add Item”);
  addItem.onClick = function() {
  testArr.push (‘Bar’ + ” ” + (testArr.length + 1));
  grpListbox.remove(grpListbox.children[0]);
  myListbox = addListBox (grpListbox, testArr);
  win.layout.layout(true);
  //updateListboxArray(myListbox);
  //$.writeln (testArr.length + ” ” + myListbox.items.length);
  }

  // BTN: Clear Listbox
  var removeAllItems = win.add(“button”, undefined, “Clear Listbox”);
  removeAllItems.onClick = function() {
  // Clear the array
  testArr = [];
  updateListboxArray(myListbox);
  }

  // Update listbox items
  function updateListboxArray(listbox) {

  // Clear listbox first
  listbox.removeAll();

  // Create new listbox items from array
  var i = 0;
  while (listbox.items.length < testArr.length) { listbox.add (“item”, testArr[i]); i++;}
  }

  // Quit BTN
  win.quitBtn = win.add(“button”, undefined, “Close”);
  win.quitBtn.onClick = function() {
  win.close();
  }

  // Window Settings
  win.onResizing = function () { this.layout.resize(); };
  win.onShow = function () { win.layout.resize(); };
  win.center();
  win.show();
  }
