Description Duane Clark 2007-10-26 17:56:39 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.8.1.5) Gecko/20070727 Fedora/1.1.3-2.fc7 SeaMonkey/1.1.3

Description of problem:
When scrolling in the file selection dialog using the mouse wheel, one click of the mouse wheel makes the selection scroll by one page plus one line. This means some entries in the dialog don't get displayed.

nedit implements mouse wheel scrolling by overriding the translations for various forms of <Btn4Down>,<Btn4Up>. Lesstif apparently decided to add builtin support for mouse wheel scrolling, but they did it by adding the translations to the variations of <Btn4Down>. The effect is that using the scroll wheel causes the list to scroll by the number of lines defined by lesstif, plus the number of lines defined by nedit. Since lesstif by default scrolls by a page minus one line, the additional scrolling by nedit causes the window to scroll too far. 

The fix is to change nedit to use variations of <Btn4Down>, and then when nedit overrides the translations, it will override the default lesstif translations. This will restore normal behavior of nedit. A patch to do this has been posted to the nedit mailing list, though not apparently incorporated into nedit:
