Menu
Before you start shooting me down i have checked for answers and i have googled till my fingers bled but i havent been able to find a simple, concise answer. So im asking again for all those that might have this problem.
Question: how to open a new window with a formpanel in side.
Context: i have an app that lists lots of items, i want someone to edit an entry, i want a new window to open so they can edit properties then hit save. A standard thing you find in a lot of applications.
Architecture: I have one client module called UI, it has a dozen classes that draw widgets and fill a main area when selected from a menu. I have a single html page called UI.html which has the tag in the head. Thats it.
Options Ive Seen
Call Window.Open() but you need to define a html file. I dont have one. I can create an empty one but how do you inject a widget in to it ?
use jsni $wnd to create a new window and get a reference to it. But how do i inject a form panel into it ??
use a popuppanel. They look sucky - plus if opening a window through JS is quite simple i would expect it to be in gwt.
Maybe im miss understanding how to use GWT i dont know.
Any help would be appreciated
Thanks

The way i got this to work is as follows: i wrote a jsni method to open a new window
public static native BodyElement getBodyElement() /*-{
var win = window.open("", "win", "width=940,height=400,status=1,resizeable=1,scrollbars=1"); // a window object
win.document.open("text/html", "replace");
i added a basic body to the new window and returned the body element
win.document.write("<HTML><HEAD>"+css1+css2+"</HEAD><BODY><div class=\"mainpanel\"><div style=\"width: 100%; height: 54px;\"><div id=\"mainbody\"class=\"mainbody\" style=\"width: 100%;\"></div></div></div></BODY></HTML>");
win.document.close();
win.focus();
return win.document.body;
}-*/;
i then called this method from my main java method
BodyElement bdElement = getBodyElement();
I then injected my panel which has lots of widgets into the returned body element
SystemConfiguration config = new SystemConfiguration(); bdElement.getOwnerDocument().getElementById("mainbody").appendChild(config.getElement());
