I am working on a Table Browser Stack. Simply, I've implemented it using several scrolling fields as the columsn of each table. Each scroll field overlaps the other's scroll bar, leaving the rightmost scroll bar visible. In this sense, I can use the scroll bar of the rightmose field to "control" the scrolling of the other fields. Unfortunately, the only possible way I can think of doing the scrolling of the other fields is to use a contant idle message that checks the scroll value of the rightmost field. Once it's changed, all the scroll fields will scroll accordingly in a big "jump". My problem is: is tha a better way to do this, or are there any XCMDs which allow this to be done? Actually I may be missing something: how does a scroll field "knows" that it has been scrolled and thus sets the scroll value properly? What message does Hypercard sends to the field?
