Hi All,
I just needed some help regarding a functionality where i need to
print the contents of a widget.
I am using the Print.it() function. I am able to print the HTML
string using the function Print.it("Just <b>Print.it()</b>!"). This
happens successfully, but am not able to print the contents of a
particular rootPanel. The rootPanel has a couple of buttons and a
textBox with some text. I have been using the following command for
this
Print.it(rootPanel.get("__printingFrame"));
I know I am missing something here. But am not sure how to proceed.
When i fire this command I just get the text " [object] " printed.
Can someone help me out at this point? What else do i need to do to
get the contents of the TextBox printed.
This was the entry that I made in html file.
<iframe id="__printingFrame" style="width:0;height:0;border:0"></
iframe>
I saw some previous codes where I got some info, but am looking out
for a very specific example where a textBox is passed as an argument
and I get only the contents of it printed.
Can someone please suggest what do I need to do?
regards,
Abhiram

You can do it with a class and a way to pass a string to it.
// ========= class code ===============
public class PrintWidgetClass2 {
native void printx(String s) /*-{
var win1 = window.open('', 'reportwindow');
win1.document.open();
win1.document.write("<head><title>Report</title>");
win1.document.write("<style> body,td {font-family:sans-serif;font-
size:10pt;}</style>");
win1.document.write("<script> \r\n")
win1.document.write("function Print(){window.print()}</script>")
win1.document.write("</head><body onload=\"Print()\">");
win1.document.write(s);
win1.document.write("</body></html>");
win1.document.close();
}-*/;
public void printIt(String html){
printx(html);
}
}
// ========== end of class code ============
Now for a way to call it. Say you have a widget (panel, whatever) that
you want to print. Use this code:
// ========= begin calling code ===========
StringBuffer sb = new StringBuffer();
sb.append(titlePanel.getElement().getString());
sb.append(header.getElement().getString());
sb.append(dataList.getElement().getString());
PrintWidgetClass2 cc = new PrintWidgetClass2();
cc.printIt(sb.toString());
// ========== end of calling code ==========
Notice that in this case the code puts together several widgets, not
just one, and prints the combined result
// ========= class code ===============
public class PrintWidgetClass2 {
native void printx(String s) /*-{
var win1 = window.open('', 'reportwindow');

win1.document.close();

Hi,
this print method is in Document or Window object if i am not wrong.
you can print the content using "jsni" using $doc.print or $wnd.print
