Okay, I have add to add a test to see if the compression is turned on
and the name changes to:

PassedInPaintObject.aA_e2.F_e2;

I will post an update in the demos group

Chris,

The name can literally be *anything* with compression turned on, and will
change as the EWB framework/your application code changes.  The compression
is *dynamic*, and automatically adapts to the usage of literals in the
application.

So how do I find the ID of the TPaint component with compression turned on.

I can do a getElementById(MyPaint.tcomponent_fname) when the compression
is turned off.

I have got around this for the moment by passing in the TPaint object
name as a string and doing the following:

var p = document.getElementById(paint1Name);
   if(p != null)
   {
      var pc = p.firstChild;
      var pcc = pc.getContext("2d");
      pcc.fillText("Test",10,10);
   }
   else
      alert("p = NULL");

Is there a way where I can pass in the TPaint as an Object and read the
id from that object?

Also is it safe to assume that the FirstChild of a TPaint object is
always the TCanvas?

Chris,

That's about the only way that you can do it safely.

You'll run into the same identifier issue with compression.

The main issue is that you're mixing some of the presentation parts of the
EWB framework with external JavaScript, and that's going to always be
difficult without using a descendant class that has direct access to the DOM
elements used.  This will become easier in EWB 2.0, since then you'll be
able to use such descendant classes in the IDE.

Yes.

Tim:

Do you have an aproximate date on the 2.0 release?

TIA

okay, no problem i can live with passing in the name of the scroller.
look forward to version 2, if you need a beta tester for v2 i am pretty
good at breaking most things 《g》

No.  I'm way behind now, due to our web server migration and EDB 2.15 taking
longer than expected, so I'm not going to even attempt a guess until I get
closer to being done.
