[Xerte] Inserting Special Characters

[Julian Tenney]

Take a wild guess what Selection.getFocus(); returns?

 

The textField?

 

Nope - a String. Cosmic.

 

You need

 

this.currentTF = eval(Selection.getFocus());

 

to actually get the textField.

Exactly my thinking:

 

INTERFACE.prototype.trackTextFields = function(){

                

                this.onSetFocus = function(){

                                

                                delete this.currentTF.onChanged;

 

                                this.currentTF = Selection.getFocus();

                                

                                debug("got " + this.currentTF);

                                

                                this.currentTF.onChanged = function(tf){

                                                debug("CHANGED");

                                }

                }

                Selection.addListener(this);

}

 

So I enable it by calling rootIcon.trackTextFields; I see the debug as
the focus changes, but I am not seeing the change handler fire - WTF? I
need to know the current TF AND the position of the caret, so that when
I click my special char insert button, I know where to put it.

Maybe a global func that holds the tf id of the last tf with focus?

<pseudo>
if object with focus=TF {
last_active = TF ID
}
</pseudo>
