Summary: Make mouse wheel scrolling compatible with lesstif
Initial Comment:
In the various dialogs (and in particular the file selection dialog is where I
came across this), 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, this makes it impossible to use the mouse
wheel.
Changing nedit to use just the variations of <Btn4Down> causes nedit to
completely override the lesstif defaults, returning normal operation.
I am running this on Fedora 7, with lesstif 0.95.0-20, which actually seems to
work pretty good with nedit.
