Hi, I'm having problems with ScrolledComposite.
Method getOrigin() in org.eclipse.rap.rwt.custom.ScrolledComposite.java
always return (0, 0), because content.getLocation() returns Point(0,0)
although the scroll origin isn't at the beginnig of the content
public Point getOrigin() {
checkWidget();
Point result;
if( content == null ) {
result = new Point( 0, 0 );
} else {
Point location = content.getLocation();
result = new Point( -location.x, -location.y );
}
return result;
}
And when I call setOrigin the ScrolledComposite behaviour isn't fine, I
lose scrollbars or I'm not be able to reach the top of my content any more.
Any help ?
Regards.
Roberto.

Hi again, I think that the problem is a Javascript problem, the
ScrolledComposite.java seems to be well implemented but when content has
a negative location (setted manually with setOrigin()) the browser
doesn't know how to paint it and when the scrollbars are moved by the
user the content location in ScrolledComposite.java isn't modified, so
if you call getOrigin() the value returned is obsolete.
I hope that can help you to solve it.
Bye.

OK, I will use bugzilla next time :-)
This was faster for me and I'm a bit impatient ;-)
