javascript - How to place a Xul window as "Always On Top"? -


i found this file @ google code function:

function setalwaysontop() {     var chktop = document.getelementbyid("itmalwaysontop");     var xulwin = window.queryinterface(ci.nsiinterfacerequestor)         .getinterface(ci.nsiwebnavigation).queryinterface(ci.nsidocshelltreeitem)         .treeowner.queryinterface(ci.nsiinterfacerequestor)         .getinterface(ci.nsixulwindow);     if(chktop.getattribute("checked") == "true") {         xulwin.zlevel = xulwin.raisedz;     } else {         xulwin.zlevel = xulwin.normalz;     } }

the parts of need just:

var xulwin = window.queryinterface(ci.nsiinterfacerequestor)         .getinterface(ci.nsiwebnavigation).queryinterface(ci.nsidocshelltreeitem)         .treeowner.queryinterface(ci.nsiinterfacerequestor)         .getinterface(ci.nsixulwindow); xulwin.zlevel = xulwin.raisedz;

but i'm not finding where's ci defined. idea can be? or other idea of how set window on top? (that solution "just windows" don't fits me).

--update

i'm reading nsiwindowmediator, has methods handle window z order. it's saying methods should used c++, not javascript. means code should used xpcom components (i should xpcom component open window)? used confirm?

i'm still reading anyway.

--update

i've tried nsiwindowmediator (with xpcom component) nothing when set z level.

still way put window aways on top..

--attempt 'alwaysraised':

test.xul:

<?xml version="1.0"?> <?xml-stylesheet href="chrome://global/skin/" type="text/css"?>  <window width="400" height="300"     onload="open('top.xul','greenfoxchannelwindow','chrome, alwaysraised');"     xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">      <label value="main window"/>  </window>

top.xul:

<?xml version="1.0"?> <?xml-stylesheet href="chrome://global/skin/" type="text/css"?>  <window width="400" height="300"     xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">      <label value="on top"/>  </window>

didn't worked.

--attempt 'zlevel':

test.xul:

<?xml version="1.0"?> <?xml-stylesheet href="chrome://global/skin/" type="text/css"?>  <window width="400" height="300"     onload="open('top.xul','greenfoxchannelwindow','chrome');"     xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">      <label value="main window"/>  </window>

top.xul:

<?xml version="1.0"?> <?xml-stylesheet href="chrome://global/skin/" type="text/css"?>  <window width="400" height="300" zlevel="6"     xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">      <label value="on top"/>  </window>

didn't worked. nither alwaysraised setted, or adding higher or lower zlevel test.xul (with top.xul zlevel="6")

found: open using opendialog, , on top.

ex:

<?xml version="1.0"?> <?xml-stylesheet href="chrome://global/skin/" type="text/css"?>  <window width="400" height="300"     onload="opendialog('top.xul','topwindow','chrome');"     xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">      <label value="main window"/>  </window>

top.xul:

<?xml version="1.0"?> <?xml-stylesheet href="chrome://global/skin/" type="text/css"?>  <window width="400" height="300"     xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">      <label value="on top" />  </window>
