Hi,

Take a look at WIDGET_CONTROL and the SET_TEXT_TOP_LINE keyword.
Here's the online help for it...

SET_TEXT_TOP_LINE
This keyword applies to widgets created with the WIDGET_TEXT
function.
Set this keyword to the zero-based line number of the line to be
positioned on the topmost visible line in the text widget's viewport.
No horizontal scrolling is performed. Note that this is a line number,
not a character offset.

Cheers,
Ben
