Hello,
I am working with PV-Wave 6.1 on a VAX-VMS system. The problem that I
am having is getting a text or picture box (with scrollbars) to scroll
programmatically.
I am writing multiple lines of text to the box, more than can be visible.
I can scroll the text manually (using the slider). However, whenever I
append to the string, the text box repositions to the beginning of the
string. What I am interested in doing is positioning to the end of the
string.
Since the documentation is not ideal in its discussion of the scroll
keyword, reading the manuals has been of little help.
Has anyone out there figured out how to accomplish this?
Thanks
Mike Daniel

Hi,
You will have to get clever with ...
WIDGET_CONTROL, widgetID, set_text_top_line = lineNumberToPutAtTop
This command puts the line you specify at the top of the visible text
widget. It's not too hard, you just have to keep track of the number of
lines in the entire text body and the number of lines visible in the widget.
