[Xerte] text input focus

Fri Aug 27 16:28:19 BST 2010

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?

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?
