After a couple of hours testing yesterday's lyx-1.5,
two problems stand out:
* I can move the cursor out of the window! Normally, lyx scrolls
down when the cursor is on the last line
in the main window and I press down arrow. Now, the cursor
just keeps going down and disappear from the window. :-(
Actually typing anything will correct the situation, the document will
then jump so the cursor is within the visible area. A bit too eager on
the drawing optimizations?
Man, I think you svn updated in the few hours between the optimisation
and the cursor navigation fix. Sorry about that but current svn should
be all right.
Good, I'll svn update when I get time. Nice to hear it is already done.
* Crazy scrollbar!
Due to the problem above, I try to use the scrollbars to find the
cursor.
Scrolling by clicking the little arrows on the scrollbar jumps one
line.
That part is fine.
Good.
Scrolling by dragging the thumb is also fine. It may eat up to 100%
of the 2.4GHz cpu capacity, but feels snappy enough.
Good. I remember you were the first to complain about that ;-)
Yes. Less cpu usage is a bonus - snappiness is the important thing.
It'd be interesting to see how lyx fares on my low-powered portable.
Scrolling by clicking between the thumb and the little arrow button
is worse. Doing this, I expect a jump the size of one window, perhaps
a single line or two less than that. (In case of big images, please
use a screenful minus a _standard_ line or two, not an actual line!)
Unfortunately, the jump is much smaller, three lines or less. This is
way too little! It is supposed to be like page down, which at least
goes half a screen. Now that isn't exactly too much either . . .
Is it different from 1.4 behaviour? I guess this is easily adjustable.
I haven't used 1.4 much. It is definitely a regression from 1.3, and the
behaviour is useless. page down or clicking this sport in the
scrollbar is supposed to be a big jump, not just "a line or two". This
is for speedy navigation.
We may discuss whether to jump half a page or (almost) a whole
page, but "a line or two" is simply a bug. I have a strong
preference for a whole page, like most scrolling software do.
Emacs does half pages though, so perhaps some people like that.
Due to problems already mentioned, I press and hold the scrollbar
down, either the scrollbar arrow or in the jumpscroll area above.
This is where it really breaks down. The document scrolls, and when
I release the mouse, it keeps scrolling for a long time. It is
just like
keyboard autorepeat gone bad, buffering lots of extra keypresses.
Except that this is a mouse button, not a keyboard key.
I can't reproduce that under Windows. Only a mouse release moves the
scrollbar, keeping the mouse pressed do not affect scrolling here...
Really? These buttons don't auto-repeat the same way the arrow keys do?
Strange - surely they do that in other windows apps like notepad?
