Simulate scroll with Scroll-wheel ()

[a.bitsche]

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.

maybe you can use the arrow keys on the Keyboard instead...

ui.keyclick(WT.ARROWDOWN);

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>
