RichTextBox has such dom level hierarchy:
<iframe>
<html>
<body>
//****************I need to manipulate this body element
</body>
</html>
</iframe>
________________________________________________________________________
I found setting style name to iframe doesn't work,and It must be set to
body element. I tried to do it like this(in constructor):
________________________________________________________________________
Element body = ((FrameElement)
getElement().cast()).getContentDocument().getBody();
body.setClassName("richTextArea");
A NPE got thrown out on this boy element,and even I wrapper them like
this:
________________________________________________________________________
Scheduler.get().scheduleDeferred(new ScheduledCommand()
{
@Override
public void execute()
{
Element body = ((FrameElement)
getElement().cast()).getContentDocument().getBody();
body.setClassName("richTextArea");
}
});
And the actually problem is RichTextBox got rendered weirdly,when it is
attached to DOM,its inner stuff(html,body) didn't got generated,even I
wrapper these lines into onload() method,NPE got thrown out sometime,but
if wrapping them into a timer,then schedule a relative long waiting
time,no NPEs,but you know,I can't let something depends on this
unpredicted "relative long waiting time".And I do need manipulate body
element to register cut/paste event by JSNI,Can anyone tell how to get
body element correctly?
