Description athompson 2005-04-11 21:08:31 UTC
i'm getting nit-picky, but scrollbar buttons that scroll by arbitrary amounts
vex me. this is especially true of windows like the output window, which scrolls
by an amount which is not divisible by the line height, so the text tends to
'drift' as you scroll.

this could also be considered a UI defect because every scroll bar in the IDE
seems to scroll by a different amount when itsbuttons are pressed. the closest
thing to a standard these days seems to be to scroll by exactly one line for
each button press, at least for fixed-height text. please change the buttons to
scroll by this amount. see issue 57532.

Just adding a note - this should be done so that scrolling happens by one line
only up to a threshold amount of output - after that it should scroll be more
lines but never more than half the total number of lines the output window can
hold (otherwise pressing and holding the scrollbar button is useless if you have
an immense amount of output - the threshold for this should be somewhere around
1000 lines).

still relevant for 6.  marking as a defect (but lowering the priority) for the
reason in the opening comment.
