Hi,
I'm trying to implement a console view where text can be appended, but
the Composite.getVerticalBar() method seems to be missing from RAP. Any
ideas?
Thanks,
Mike

Thanks, I've tried to wrap the Text widget in a ScrolledComposite and it
looks fine but I have no control over the scroll bars e.g.
scroller.getVerticalBar().setOrigin() has no effect. My code for setting
it up is as follows:
public void createPartControl(Composite parent) {
parent.setLayout(new FillLayout());
scroller = new ScrolledComposite(parent, SWT.H_SCROLL | SWT.V_SCROLL);
console = new Text(scroller, SWT.WRAP);
scroller.setContent(console);
scroller.setExpandHorizontal(true);
scroller.setExpandVertical(true);
}

Hi Mike,
the getVerticalBar#setOrigin method isn't implemented yet. I guess
you tried ScrolledComposite#setOrigin(x,y).
I did some investigations with code, based your snippet, but also
couldn't get it to do what I wanted to.
parent.setLayout( new FillLayout() );
scroller = new ScrolledComposite( parent, SWT.H_SCROLL
| SWT.V_SCROLL );
scroller.addControlListener( new ControlAdapter() {
public void controlResized( ControlEvent e ) {
Rectangle parentBounds = scroller.getClientArea();
scroller.setMinSize( parent.computeSize( parentBounds.width,
SWT.DEFAULT ) );
}
} );
console = new Text( scroller, SWT.WRAP );
String text = "";
for( int i = 0; i < 400; i++ ) {
text += "line" + i + "\n";
}
console.setText( text );
scroller.setContent( console );
scroller.setExpandHorizontal( true );
scroller.setExpandVertical( true );
scroller.setOrigin( 0, 200 );
The setOrigin() call seems to be ignored at all, and the text widget
starts to scroll by itself from time to time, but I haven't had the
time to dig deeper into this.
I you have a snippet that works properly on SWT, but doesn't do its
job in RAP, feel free to file a bug.
Cheers,
Rüdiger
