Managing the Image Control
The behaviour of the image control, like scrolling and zooming, can also be managed by an add-in. The appropriate
service is called
SourceCtrl
service. Like the other services it must first be provided which is done by the lines
Dim sourceCtrlSink As DOKuStarValidationServices.SourceCtrlService
and Set
sourceCtrlSink = dsValApp.Services("SourceCtrl"):
Let us now implement a special behaviour of the image control. We want to use three key combinations to set the
zoom factor to 300, 200 and 100 respectively and an additional one to scroll to the right.
The zoom factor of the image control can be changed using
sourceCtrlSink.Zoom
. Using
sourceCtrlSink.ScrollTo
allows to scroll to a specified position. In our example we use
Control
+
3
,
Control
+
2
and
Control
+
1
to switch to a specified zoom factor and
Control
+
R
for scrolling to the right.
