[Project_owners] Reuse of window-watcher windows

[Jesper Staun Hansen]

Hello,

Considering this code http://pastebin.mozilla.org/544425 once I run 
test.showbox(), then the window-watcher will keep existing even if the 
window is closed. Question however is... How to I reuse the window 
watcher to reopen the window?
I want to make what can be described as "persistent window when 
possible". (that would be reuse the window if  it hasn't been closed yet)

After the window is closed the stuff available that the window-watcher 
is leaving behind is:
*Methods of prototype: *addEventListener, alert, atob, back, blur, btoa, 
captureEvents, clearInterval, clearTimeout, close, confirm, 
disableExternalCapture, dispatchEvent, dump, enableExternalCapture, 
find, focus, forward, getAttention, getAttentionWithCycleCount, 
getComputedStyle, getSelection, home, maximize, minimize, moveBy, 
moveTo, open, openDialog, postMessage, print, prompt, releaseEvents, 
removeEventListener, resizeBy, resizeTo, restore, routeEvent, scroll, 
scrollBy, scrollByLines, scrollByPages, scrollTo, setCursor, 
setInterval, setResizable, setTimeout, showModalDialog, sizeToContent, 
stop, updateCommands
*Fields of prototype: *STATE_MAXIMIZED, STATE_MINIMIZED, STATE_NORMAL, 
browserDOMWindow, closed, controllers, crypto, defaultStatus, 
directories, document, frameElement, frames, fullScreen, globalStorage, 
history, location, locationbar, menubar, name, opener, pageXOffset, 
pageYOffset, parent, personalbar, pkcs11, screen, scrollMaxX, 
scrollMaxY, scrollX, scrollY, scrollbars, self, sessionStorage, status, 
statusbar, toolbar, top, window, windowState
*Unreachables of prototype: *applicationCache, content, innerHeight, 
innerWidth, length, navigator, outerHeight, outerWidth, screenX, 
screenY, title

None of these seems to allow the window to be reopened. (except 
restore(), but that seems related to the general window restore).

Other info:
var watcher = 
Components.classes["@mozilla.org/embedcomp/window-watcher;1"].getService(Components.interfaces.nsIWindowWatcher); 

Stuffz available:
*Methods: *QueryInterface, getChromeForWindow, getNewAuthPrompter, 
getNewPrompter, getWindowByName, getWindowEnumerator, openWindow, 
registerNotification, setWindowCreator, unregisterNotification
*Fields: *activeWindow


Any ideas?
