#162 getWidth() / Height() problems with NS6

[Bernard Squale]

...
DynAPI.onLoad = function() {
label1 = new Label('Some text')
DynAPI.document.addChild(label1)
// returns a value with IE/NS - Win32
alert(label1.getWidth())

label2 = new Label('Some text')
d = new DynLayer()
d.addChild(label2)
DynAPI.document.addChild(d)
// returns a value with NS4 / IE - Win32
//but 'null' with NS 6.1 - Win32, DyAPI 2.54
alert(label2.getWidth())
}

I have a similar problem with NS6.2... I have the following:
DynLayer.prototype.addPopupMenu = function
(x,yAct,menuNames,menuLinks,menucolor,bordercolor)
{
var borderLayer = new DynLayer(null,(x-
4),yAct,0,0,bordercolor);
DynAPI.document.addChild(borderLayer);

var spacerLayer = new DynLayer

(null,1,0,0,0,menucolor);
borderLayer.addChild(spacerLayer);

var menuLayer = new DynLayer

(null,2,0,0,0,menucolor);
spacerLayer.addChild(menuLayer);
var menuText = "";
for (var i = 0; i < menuNames.length; i++)
{
menuText += "<A href=\""+menuLinks[i]+"\"
class=\"menu\">"+menuNames[i]+"</A><BR>";
}

menuLayer.setHTML\(menuText\);   
var w = menuLayer.getContentWidth\(\); 
var h = menuLayer.getContentHeight\(\);
menuLayer.setSize\(w,h\);

spacerLayer.setSize\(\(menuLayer.getWidth\(\)+4\),

(menuLayer.getHeight()+2));

borderLayer.setSize\(\(spacerLayer.getWidth\(\)+2\),

(spacerLayer.getHeight()+1));
}

In NS6.2, a thin layer loads without any text... the only
workaround is to set borderLayer.setSize(200,200) or some
other actual numbers.

Got the same problem....and this is why my dynTabStrip
object does not work under NS6

I'm trying to find a solution

This is a bug in Mozilla. It doesn't set the offsetWidth
immediately after creating the element. The only workaround
at the moment is to use some sort of timeout and then
retrieve the offsetWidth/Height.

I have a partial solution. Since there is no sleep or wait
in JS you can't have syncrouns code that works here so I
wrote 2 async functions to that call a specified callback:

/* Code snip */

DynLayer.prototype.cbGetContentWidth = function()
{
this.asyncw(this.elm.offsetWidth);
this.elm.style.width = this.tw;
}
DynLayer.prototype.asyncGetContentWidth=function(result)
{
this.tw = this.elm.style.width;
this.elm.style.width = "auto";
this.asyncw = result;
setTimeout("DynObject.all
['"+this.id+"'].cbGetContentWidth()",1);

};
DynLayer.prototype.cbGetContentHeight = function()
{
this.asynch(this.elm.offsetHeight);
this.elm.style.height = this.th;
}
DynLayer.prototype.asyncGetContentHeight=function(result)
{
this.th = this.elm.style.height;
this.elm.style.height = "auto";
this.asynch = result;
setTimeout("DynObject.all
['"+this.id+"'].cbGetContentHeight()",1);
};
/* End of Snip */
An example usage:
function alertWidth(w)
{
alert(w);
}
if (is.ns6)
myLayer.asyncGetContentWidth(alertWidth);

The current method in DynLayer 2.9 and 2.5.6. It actually
breaks NS6.2.

NS6.2 does not initially set style.width. So what happens
is this.

INITIALLY: offsetWidth = correct value
set style.width = "auto"
offsetWidth = still correct value
set style.width = back to prior value (empty string)
offsetWidth = 0

So in NS 6.2, you DON'T want to use the style.width trick
because by manually setting style.width = '' (empty string)
it resets offsetWidth to 0.

I added the following statements to getContentWidth/Height
for NS

if (dynapi.ua.ns4) return this.doc.width;
else if (dynapi.ua.ie) {
if (dynapi.ua.platform=="mac") return
this.elm.offsetWidth;
return parseInt(this.elm.scrollWidth);
}
// added by BT 2/13/2002
else if (dynapi.ua.ns6) {
return parseInt(this.elm.offsetWidth);
}
// -----
else {
....

Now after reading this bug report, I may need to add a
minor version check rather than just for ns6. It looks
like the NS bug was fixed in 6.2.
