用GWT中的Widget打开一个新窗口 [英] Opening a new Window with a Widget in GWT
问题描述
在你开始拍摄我之前，我已经检查了答案，并且我已经使用了Google，直到我的手指流血，但是我还没有找到简单，简明的答案。所以我再次询问所有可能有这个问题的人。
问题：如何用一个formpanel打开一个新窗口。
上下文：我有一个列出大量项目的应用程序，我希望有人编辑条目，我想要打开一个新窗口，可以编辑属性，然后点击保存。一个标准的东西，你在很多应用程序中找到。
架构：
我有一个名为UI的客户端模块，从菜单中选择时，可以绘制小部件并填充主区域。我有一个名为UI.html的HTML页面，头部有标签。这就是它。
选项我看过
-
调用 Window.Open（），但您需要定义一个html文件。我没有。我可以创建一个空的
使用 jsni $ wnd 创建一个新窗口并获得对它的引用。但是，我如何在其中注入一个表单面板？ 使用 popuppanel 。 -
他们看起来很烂 - 再加上如果通过JS打开一个窗口非常简单，我预计它会在gwt中。
也许我很想知道如何使用GWT我不知道。
任何帮助将不胜感激
谢谢
p>我得到这个工作的方式如下：
i写了一个jsni方法来打开一个新窗口
public static native BodyElement getBodyElement（）/ * - {
var win = window.open（，win， WIDTH = 940，高度= 400，状态= 1，可调整大小= 1，滚动条= 1）; //一个窗口对象
win.document.open（text / html，replace）;
我在新窗口中添加了一个基本主体并返回了主体元素
'pre> win.document.write（ < HTML>< HEAD> 中+ CSS1 + CSS2 +< / HEAD>< BODY>< DIV class = \mainpanel \>< div style = \width：100％; height：54px; \>< div id = \mainbody \class = \主体\style = \width：100％; \>< / div>< / div>< / div>< / BODY>< / HTML>）;
win.document.close（）;
win.focus（）;
return win.document.body;
} - * /;
然后我从我的主要java方法调用这个方法
BodyElement bdElement = getBodyElement（）;
然后我的面板中有很多小部件插入到返回的body元素中
SystemConfiguration config = new SystemConfiguration（）; 。bdElement.getOwnerDocument（）的getElementById（ 型主体）的appendChild（config.getElement（））。
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());
