Simulate scroll with Scroll-wheel ()

Postby a.bitsche » Fri Jun 01, 2007 1:43 am

Is it possible to simulate the scroll-wheel action?
With the mouse-button in the middle it's possible to scroll and click but the actions won't be recorded.

Thanks for the reply.
But unfortunately this won't work.

Unfortunately we do not have scrollbar support. For this you will have to resort to a low level tool like abbot. Have you tried the abbot CanvasTester? This class safely proxies
org.eclipse.swt.widgets.Canvas.scroll(int, int, int, int, int, int, boolean). The scroll javadocs are included below:

Code: Select all
* Scrolls a rectangular area of the receiver by first copying
* the source area to the destination and then causing the area
* of the source which is not covered by the destination to
* be repainted. Children that intersect the rectangle are
* optionally moved during the operation. In addition, outstanding
* paint events are flushed before the source area is copied to
* ensure that the contents of the canvas are drawn correctly.
* @param destX the x coordinate of the destination
* @param destY the y coordinate of the destination
* @param x the x coordinate of the source
* @param y the y coordinate of the source
* @param width the width of the area
* @param height the height of the area
* @param all <code>true</code>if children should be scrolled, and <code>false</code> otherwise
* @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>
