Is that possible to create Composite/Widget in GWTD using existing html page content? (assuming for a moment basic requirement as to get something drawn in design view):
HTML Page:
- Code: Select all
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN">
<html>
<head>
<meta name="generator" content="HTML Tidy, see www.w3.org">
<meta name='gwt:module' content= 'com.mycompany.project.TestingWidgets'>
<link type="text/css" rel='stylesheet' href= 'TestingWidgets.css'>
<title></title>
</head>
<body>
<!-- element on page -->
<div id="front">
</div>
<!-- gwt script -->
<script type="text/javascript" language="javascript" src= "com.mycompany.project.TestingWidgets.nocache.js">
</script>
</body>
</html>
so there is:
- Code: Select all
<div id="front"></div>
.css:
- Code: Select all
body {
margin: 0;
}
#front {
width: 200px;
height: 200px;
background-color: red;
}
composite:
- Code: Select all
package com.mycompany.project.client.ui;
import com.google.gwt.user.client.DOM;
import com.google.gwt.user.client.Element;
import com.google.gwt.user.client.ui.Composite;
import com.google.gwt.user.client.ui.Widget;
public class Front extends Composite {
public static class WidgetWrapper extends Widget {
public WidgetWrapper(Element element) {
setElement(element);
}
}
/**
* @wbp.factory
*/
public static final Widget getFront() {
return new Front.WidgetWrapper(DOM.getElementById("front"));
}
public Front() {
final Widget front = Front.getFront();
initWidget(front);
}
}
this throws errors in Design view (very lengthy ones):

however if I change existing div element from html page to non-attached one:
- Code: Select all
package com.mycompany.project.client.ui;
import com.google.gwt.user.client.DOM;
import com.google.gwt.user.client.Element;
import com.google.gwt.user.client.ui.Composite;
import com.google.gwt.user.client.ui.Widget;
public class Front extends Composite {
public static class WidgetWrapper extends Widget {
public WidgetWrapper(Element element) {
setElement(element);
}
}
/**
* @wbp.factory
*/
public static final Widget getFront() {
return new Front.WidgetWrapper(DOM.createDiv());
}
public Front() {
final Widget front = Front.getFront();
initWidget(front);
}
}
then it works fine in GWTD design view of that composite,
I'm asking because I'm trying to reuse 3rd application generated html content. I can easily reuse .CSS and recreate generated html using custom widgets, however reusing attached html tags would be easier and better (of course it would require some patching to GWT toolkit uiobject/widget/panel/complex panel classes).
regards,
peter
