[Xerte] text input focus

Fri Aug 27 17:17:15 BST 2010

So Selection.setFocus doesn't work, but Selection.getEndIndex() and Selection.setSelection(e,e) do?
How uncool.

Dunno – what happens if you try ;-)

We could add another parameter to the setselection function for
caret index if you need to control it and find you can’t,

?

What about these:

e = Selection.getEndIndex();

Selection.setSelection(e,e);

will they have to separately functioned as well?

Anything in the Selection class?

Not sure. On occasion some
classes – in this case Selection – don’t appear to be available to the xerte script,
or rather the interpreter is screwing with them. It’s odd because it works at
author time (which is quite an old Flash Player) and not at runtime in the
browser…

Anyway, we fixed it.

Sorry my bad.

I didn't replace all the engine swfs. Never did get a real handle on what gets
copied from where on publish.

Yes! :-)

So what's happening? Focus is somewhere weird when it's in the browser?

Right, we need an engine
function to do it. If I make this in the engine:

function setFocus(tf){

Selection.setFocus(tf);

}

I can call it and it works.
Replace your engine with this one.

Within
Xerte desktop if I test for dave = eval(Selection.getFocus());

I'm pretty much getting undefined's in browser.

Even after I manually click on a field and then use an onFocus event trigger to
trap that, checking what is focussed gives "undefined".

I think so. What that was
about wsa the charPad in the template wizard, which has buttons loaded with
special characters for French, German etc.

What happens is the user
clicks a button and the special char gets inserted into the current text field,
and the focus is put back to the text field and IT WORKS IN THE BROWSER so it
can be solved...

…so looking at the code that
does that I see

Selection.setFocus(this.currentTextField);

Selection.setSelection(this.insertPoint + 1, this.insertPoint + 1);

So, not only is the selection
being put back, we also set the selection range (because we have inserted a
character, so need to know where to put the caret) 

But I still can’t get my
simple example to work.

One difference here is that
my working code is in a compiled SWF, whilst the failing code is Xerte code.

Can't see how.

I just have a timer that runs when focus is lost, then drops through to set it
back.

I also removed the onFocus event trap to take that out of the equation.

Think this may have any part?

http://lists.nottingham.ac.uk/pipermail/xerte/2010-January/003835.html 

Is it maybe not getting a usable reference to the TE?

I tried putting both those paths hardcoded in, no luck.

With all the text entries in the templates, I'm gob-smacked no one has shouted.

Is there a way to do it in XOT?

Hm. I don’t know what the
answer is then. Nothing comes readily to mind here and I can easily reproduce
it. Is the focus getting set and then stolen by something else?

I've already tried stringing it, using a full path (_level0.engine.answers.txt)
strung and unstrung) same routine with a regular text input interaction, etc
etc.

Just less hair.

Years ago, in the dark ages of
the Flash Player, you would sometimes have to send a string when a movieclip
reference was required. See http://www.bigresource.com/Tracker/Track-flash-t4zJaAOAHv/

Where they are calling
Selection.setFocus with a string of the movieclip’s path, not a reference. Some
of the old components were foul of it as well.

Give that a whirl.

Pat, the problem is with the setFocus itself.

I can't get it to work when browsered, no matter where the original focus is.

I have a couple dummy start buttons to make sure the piece has focus.

I have a 1 sec timer set up to return focus to the TE if it loses it.

This all works as expected in IDE.

In a browser, none of it works.

The event traps are saying the OnKill and OnSet are tripping, but the setFocus
does nothing.

Could you write a function to
run onload in the flash to do a JS call to set focus?

OK, in F8 in a browser trying an initial focus on load does not work because
the F object needs to be given focus first.

Add a "Start" button prior to the setFocus attempt and of course it
starts to work because the piece now has focus.

There is a bug in Flash whereby when you set focus to an empty field you get no
caret, but there is a workaround to that.

So the identical setup in Xerte does not want to work.

It is recognizing when the field is gaining or losing focus,  but
Selection.setFocus in the browser does not give the textfield focus i.e. typing
does not appear.

Tried taking Xerte out of the
picture and built a simple flash piece?

At least that will tell us whether the
problem is on our side of things or not...

That
it doesn't work in a browser?

I stripped it down to bare bones, no embedded fonts, nothing but a script
created text field and a few event catchers.

Works fine in authoring mode, no go in browser.

If you’re trying to set the
focus to the textfield, the movie will get the focus anyway.

What
does a simple example tell us?
