Opening a new Window with a Widget in GWT
Solution 1
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());

I agree with Bogdan: Use a DialogBox.
If you can't, you Window.open()
as you mentioned in option 1:
- Create another GWT module, and form.html that will load it
Window.open("form.html?entry=54")
- Have the form gwt module read from the URL, load the entry, allow it to be edited, and provide
Save
andCancel
buttons - Close the popup when
Save
orCancel
is clicked

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

Primus over 13 yearsThanks guys for your quick replies. My beef with the dialogbox is it has no window frame nor the typical window look, url location etc.
