Hi all,
I've been playing around with the ZeroClipboard (see
http://code.google.com/p/zeroclipboard/) but I did not manage to get
it to work as of now. After having tried out different approaches /
solutions from other users (for example here
http://code.google.com/p/zeroclipboard/wiki/IdeasAndSuggestions), I'm
now asking you guys. =)
I want to copy a calculated value *from within my GWT-application* to
the clipboard so that I can use that value anywhere else using Ctrl-v
(that's what ZeroClipboard is all about right? ;-) )
I therefore put the corresponding code into my host html file
(Application.html) of my GWT-app:
<html>
<head>
<meta http-equiv="content-type" content="text/html;
charset=UTF-8">
<title>Application</title>
<script type="text/javascript" language="javascript"
src="ZeroClipbaord.js"></script>
<script language="JavaScript">
function copy() {
var clip = new ZeroClipboard.Client();
clip.setText('Copied!!!');
clip.glue( 'buttonId' );
}
</script>
<script type="text/javascript" language="javascript"
src="GWTServlet.Application.nocache.js"></script>
</head>
<body>
<iframe src="javascript:''" id="__gwt_historyFrame" tabIndex='-1'
style="position:absolute;width:0;height:0;border:0"></iframe>
</body>
</html>
My corresponding Java source-code looks like this:
public class Application implements EntryPoint {
/**
* This is the entry point method.
*/
public void onModuleLoad() {
FlowPanel table = new FlowPanel();
table.getElement().setId("FlowPanel");
Button button = new Button("ClickMe to copy to clipboard");
button.getElement().setId("buttonId");
button.addClickListener(new ClickListener(){
public void onClick(Widget arg0) {
copyInJava();
}
});
table.add(button);
RootPanel.get().add(table);
}
public native void copyInJava() /*-{
$wnd.copy();
}-*/;
}
ZeroClipboard works just fine when used in plain HTML to copy contents
to the clipboard but I did not manage to get it to work from inside a
GWT-application.
I also used FireBug to debug and apparently there is some issue when
creating the ZeroClipboard.Client() object. Nonetheless, when I run it
in plain HTML, everything is fine so I assume that the issue is due to
the fact that I'm using a GWT-app to get the job done.
Does anybody have suggestions what the problem might be?
Cheers
