Subject: 23.0.91; Emacs.app scroll-bars are incorrect
Date: Sun, 29 Mar 2009 11:51:55 +0200

Hello!

The scroll-bars are full-height although not the whole buffer is  
visible. Dragging at scroll-bar downwards scrolls the buffer until  
all its contents is scrolled away. (At least it's not as brain- 
damaged as with GTK in *Calendar* buffer!)

Hello,

I cannot reproduce this.  Could you provide details of how you set up  
the calendar mode to do this, or send a screenshot?

This is currently the std behavior of scrollbars in the NS port.  Do  
other emacsen behave differently?

I still have one of version 23.0.91 and I launched it twice with -Q.  
The upper one has the view from launching calendar, the lower  
(active) one shows the vertical scroll-bar scrolled as much down as  
possible (you might be able to see the grey gap):

[Message part 3 (text/plain, inline)]

With TinkerTool I changed a system-wide preference that all scroll- 
bars show two arrows at each end. Could be this changes the behaviour  
– or it's a Tiger (10.4.11) feature!

It's not the standard behaviour in other Cocoa applications (in  
Terminal, Mail, Preview the scroll-bar stops and I see the bottom of  
the "buffer" at the window's bottom), this looks more like copying  
the bad manners of GTK.

To most people solutions mean finding the answers. But to chemists  
solutions are things that are still all mixed up.

That's standard behavior in Emacs, mostly for technical reasons.

The screenshot looks like what I see as well.  The whole buffer IS  
visible, isn't it?  What part don't you see?  Is emacs under X11  
behaving differently?

At start, in the upper window.

> What part don't you see?

In the other window only the last day of May is visible, so most of  
this buffer (seven out of eight lines or 87.5 %) is not visible  
because scrolled away.

> Is emacs under X11 behaving differently?


It's a pity, it also scrolls (almost) all away! And therefore my  
report is not a bug report...


Sorry! I did not check, the X clients don't show a scroll-bar (except  
they're defective GTK-). Although I can see an advantage of this  
behaviour in a text buffer (last line of my writing far above the  
window's bottom, showing me that I have to continue to write) this  
behaviour and the scroll-bar are both useless in the *Calendar*  
buffer – when they don't scroll through the ages.

Closing, behavior within range defined by other ports.
