  Adding a keyboard listener to script window

  Posted by Jacob Roth on November 14, 2019 at 6:28 pm

  Hello all,

  I’m trying to write a script that will let me parent layers with nothing but the keyboard. I’ve gotten to the point where the script can change the parent of a layer, but I can’t get the script to execute without clicking a button.

  I’ve read that event listeners no longer work in ExtendScripts. Is there another way to add a keyboard command onto a UI button?

  var mainComp = app.project.activeItem;
var mainWindow = new Window("palette","The Parenter", undefined);

  var groupOne = mainWindow.add("group", undefined,"groupOne");
  groupOne.orientation = "column";

  groupOne.add("statictext", undefined,"This script Parents your layers");
  var theParent = groupOne.add("edittext", undefined, "Parent");
  var firstChild = groupOne.add("edittext", undefined, "First Child");

  var groupTwo = mainWindow.add("group", undefined, "Buttons");
  groupTwo.orientation = "row";
  var startButton = groupTwo.add("button", undefined, "Parent!");
  var cancelButton = groupTwo.add("button", undefined, "Cancel")

  startButton.onClick = function(){
  app.beginUndoGroup("Parent");
  doThings();
  }
  cancelButton.onClick = function(){
  mainWindow.close();
  }

  function doThings(){
  var setParent = parseInt(theParent.text);
  var setChildren = parseInt(firstChild.text);
  mainComp.layer(firstChild).parent = mainComp.layer(setParent);

  mainWindow.close();
  app.endUndoGroup("Parent");
  }

  mainWindow.show();
mainWindow.center();
