Re: Gtk scrollbar: thumb too short

My suggestion is to display a thumb that rises from the bottom of the
scroll bar, but is shorter than normal, as if the bottom of the thumb
were hidden beyond the end of the scroll bar.  Others may think
of a better way to indicate this situation.

    As the native scroll bars do?  The disadvantage is that then the
    thumb size in relation to the scroll bar size looses the
    connection of how much of the buffer you are seeing w.r.t. the
    size of the buffer.

Either we are miscommunicating about something basic, or I disagree.
In what I envision, the visible thumb size would reflect the amount of
real text visible in the window.  As window-start gets closer to
point-max, the amount of visible text decreases, and so should the
thumb size.

It is just a difference in interpretation.  For you a small thumb means
that the number of visible real text is small.

When I see a thumb that is 1/3 of the scroll bar size, I take that to
mean that the buffer size is about 3 times larger than what can be
displayed in a page.  If we should scroll "off the bottom" so that
the thumb becomes 1/10 of the scroll bar size, obviously the buffer
has not become 10 times the size of one page, but rather ten times
larger than the visible real text.

I don't claim that one view is better than the other, it is just
what I am used to, mainly using scroll bars in applications where the
thumb size is practically fixed as long as the content stay the same.
