Hi,
Probably more helpful is the explanation of "then in use":
then in use:
XXX.prototype.onMouseDown = function(evt)
{
if(getFocus() != this)
setFocus(this);
...
}
Hope that helps, if not feel free to ask.
Cheers,
Chris

Hi,
I have my own focus system:
//widget focusing
var gFocusObj = null;
function getFocus()
{
return gFocusObj;
}
//----------------------------------------------------------
------
function setFocus(newfocusobject)
{
if(gFocusObj && gFocusObj.killFocus)
gFocusObj.killFocus(newfocusobject);
if(newfocusobject && newfocusobject.setFocus)
{
//old and new
newfocusobject.setFocus(gFocusObj,newfocusobject);
}
gFocusObj = newfocusobject;
}
function killFocus()
{
gFocusObj = null;
}
function checkFocus(evt)
{
if(evt.button == 0)
{
if(gFocusObj && gFocusObj.killFocus)
gFocusObj.killFocus(null);
gFocusObj = null;
}
}
then in use:
function ...
{
if(getFocus() != this)
setFocus(this);
}
js objects:
XXX.prototype.killFocus = function(newfocusobj)
{
}
XXX.prototype.setFocus = function(oldfocusobject, newfocusobj)
{
}

Subject: [svg-developers] Re: No Keyboard Events
That's very cool but I'm not really interested in something browser
specific. Also, i searched everywhere through that code and found no mention
of the SVG focus events. Every element has the onfocusin event but yet every
description of it in documentation is very vague and I can find no examples.
