I have a horizontal scrollbar that controls a large panel (with a very large width, and a very small height, thus an horizontal panel).

I want the start of the scrollbar (when the knob is at max left) NOT to start at the beggining of the panel it is scrolling, but rather in a specific place that I dictate. The same for the end of the scrollbar (when the knob is at max right).

I find that the scrollbar is always bound to the panel it is scrolling, and I can’t figure out how to change its behaviour.

EDIT:

As an example, picture a normal web-page: when at the top of the page, the scrollbar knob is also at the top. When at the bottom, the scrollbar knob is at the bottom. I want to define new limits for the content, such that when the scrollbar knob reaches the top or bottom, the page is showing the limit I defined, instead of the real top and bottom.

    I solved the problem by using the JScrollbar method setValues(), which allows me to set at the same time the maximum, minimum, value and extent of the scrollbar. By setting the maximum and minimum to the values I want, the scrollbar behaves as I wanted/expected.

    The problem was that I was only setting maximum and minimum values (setMaximum, setMinimum), and since there is a strict policy at the model that minimum <= value <= value+extent <= maximum, that estrategy did not work.
