Bonjour, everybody!)
I recently set up this script for my purpose and found small bug.
When I open(create) few windows they appears in right order: new ones appears over previews according to their z-indexes. But when I close all windows they just become hidden and when I open them again in another order they become visible with old z-indexes, so some windows appears under another windows.
I can't fix it myself couse this is over my js programming level =))
Please, help! That great script need to be fine.
And another small thing. Is it possible to make Drag Handle Line got another color when its active?

Thanks in advance!

Here is a demo:
[dynamicdrive.com...]
Take a look^ This is most advanced 'windows' script I'v ever seen.

And here is a code:


var dhtmlwindow={
imagefiles:['windowfiles/min.gif', 'windowfiles/close.gif', 'windowfiles/restore.gif', 'windowfiles/resize.gif'], //Path to 4 images used by script, in that order
ajaxbustcache: true, //Bust caching when fetching a file via Ajax?

minimizeorder: 0,
tobjects: [], //object to contain references to dhtml window divs, for cleanup purposes

init:function(t){
var domwindow=document.createElement("div") //create dhtml window div
domwindow.id=t
domwindow.className="dhtmlwindow"
var domwindowdata=''
domwindowdata='<div class="drag-handle">'
domwindowdata+='DHTML Window <div class="drag-controls"><img src="'+this.imagefiles[1]+'" title="Close" /></div>'
domwindowdata+='</div>'
domwindowdata+='<div class="drag-contentarea"></div>'
domwindowdata+='<div class="drag-statusarea"><div class="drag-resizearea" style="background: transparent url('+this.imagefiles[3]+') top right no-repeat;">&nbsp;</div></div>'

Pretty HUGE ;)
And I have no idea how that work.
That a big deal to ever read all that.
Any help will be appreciated by all generations of users of this mega script ;)

in the portion of restore function it calls to create the attributes of the windows.
what exactly do you want it to do?
if you wish to have it not load on top or what your not

I fixed mine to below hope this helps

<code>

show:function(t){
if (t.lastx) //If there exists previously stored information such as last x position on window attributes (meaning it's been minimized or closed)
dhtmlwindow.restore(t.controls.firstChild, t) //restore the window using that info
else
t.style.display="block"
t.state="fullview" //indicate the state of the window as being "fullview"

dhtmlwindow.zIndexvalue++;
t.style.zIndex=dhtmlwindow.zIndexvalue;

},

</code>
