Scrolling programmatically [message #399140]

moves the handle up and down, it doesn't scroll the content. I did a
search, and apparently there is a problem with this. Or has been, since
the posts I found regarding this were pretty old. I'm wondering if this is
still the case or if there's a way/workaround to accomplish this now?

See ScrolledComposite.setOrigin:

/**
* Scrolls the content so that the specified point in the content is in the
top
* left corner. If no content has been set, nothing will occur.
*
* Negative values will be ignored. Values greater than the maximum scroll
* distance will result in scrolling to the end of the scrollbar.
*
* @param x the x coordinate of the content to appear in the top left corner
*
* @param y the y coordinate of the content to appear in the top left corner
*
* @exception SWTException <ul>
* <li>ERROR_WIDGET_DISPOSED - if the receiver has been disposed</li>
* <li>ERROR_THREAD_INVALID_ACCESS - if not called from the thread that
created the receiver</li>
* </ul>
*
* @since 2.0
*/
public void setOrigin(int x, int y)
