Hi,
I didn't notice that this thread continues ...

Application wide suffices. In SWT, which is our reference point, there
is a flag ON_TOP. Setting this flag raises a window on top of all other
windows.

Yes, this is matches the behavior of always-on-top windows in Win32. If
one creates multiple on-top windows, they all stay on top of all other
windows but can freely be rearranged, just like normal windows.

I don't agree with this point. In Windows, ON_TOP windows are also on
top of modal windows. I think this makes sense, since the purpose of a
modal window is to block the application (at least if application-modal)
but it doesn't have to be on top of all other windows. For example, a
file open dialog is usually application-modal, but you can still open
another application on top of it.
Meanwhile I added a property "alwaysOnTop" to our Window subclass and
overrode the function _sentTo like this to make sure that on-top-windows
always have a higher z-order than others:
qx.Proto._sendTo = function() {
var vAll = qx.lang.Object.getValues(
this.getWindowManager().getAll() );
vAll = vAll.sort( qx.util.Compare.byZIndex );
var vLength = vAll.length;
var vIndex = this._minZIndex;
for( var i = 0; i < vLength; i++ ) {
var newZIndex = vIndex++;
if( vAll[ i ].getAlwaysOnTop() ) {
newZIndex += vLength; // <--- raise on top of all other windows
}
vAll[ i ].setZIndex( newZIndex );
}
}
This is also my suggestion for an implementation in qooxdoo.

Ralf
