EventListener not working for edittext

[K.Daube]

Dear friends,

I'm working with FrameMaker - and there the experts of ExtendScript gave me the hint to post in this forum. But first I want to thank members of this forum, in particular Peter Kahrel and "Jongware" for the documentation they provide - filling painful gaps in the 'official' documentation.

My problem is sketched in the title: EventListener not working for edittext.

In an edittext  users can Select All and then copy the contents of  t he object and this content can also be deleted after selection. I want to make it 'user friendly': single click into the area copies the content to the clipboard, double click deletes the contents:

In the following script a click/double click into the edittext area does nothing. If I write

win.eField.addEventListener ("click (detail = 1)", hClick(), false); or hDClick() then the alert is executed without any user action on the window. Whether the last parameter is true or false has no effect.

→ What is wrong with my script?

/*  on(Double)Click.jsx ====== UTF-8 ====================================
              check possibilites to act on an edittext click/doubleclick
              in ExtendScript Toolkit CC
Comment       There is no onClick (and no onDoubleClick) for edittext
              Hence appropriate event listeners must be defined
              See JavaScript Tools Guide for the eventName in 
              controlObj.addEventListener (eventName, handler[, capturePhase]);

  win = new Window ("dialog", "on(Double)click", undefined, undefined);
  win.eField    = win.add ("edittext", undefined, "Text in field", undefined);
  win.btnCancel = win.add ("button", undefined, "Cancel", undefined);
  
//win.eField.active = true;
  win.eField.addEventListener ("click (detail = 1)", hClick, false);
  win.eField.addEventListener ("click (detail = 2)", hDClick, false);

  win.show ();
} //--- end main

hClick = function () {
  alert ("Click into edittext");
  $.writeln ("Click into edittext");
} //--- end hClick

hDClick = function () {
  alert ("DoubleClick into edittext");
  $.writeln ("DoubleClick into edittext");
} //--- end hDClick

main ();

Thank You for help

If i change the window type to palette then the script just runs through and I see the window only for a subsecond...

[Peter Kahrel · Accepted solution]

You would indeed expect you could click in a text field and select all its content. But you can't. You can add an onActivate handler, but apparently ScriptUI thinks that when it has responded to onActivate, giving in to .active = true is too much of a good thing. You can add a button and do an onClick event that activates the text field, but that's not what you want.

edittext controls don't support click events I don't think. You'd have to use onActivate, but that doesn't work either.

You'd have to run the script in a target engine. Nowadays in InDesign there's no need for that when you run the script from the Scripts panel, onky when you run it straight from the ESTK. How that plays in FrameMaker I've no idea. Maybe FrameMaker (like Photoshop) doesn't support palettes.

Thanks Peter for Your answer.

BTW in FM we can have palettes - the screen shot in my post shows it.

My thought was this: if there is no onXxxx trigger, then an eventlistener could add one..

I really wonder why the examples in my references work:
