I did
xemacs -q
M-x balloon-help-mode
M-x customize-variable truncate-lines
If I hold the mouse above the "Reset" button (which for some reason is
grey whilst the others are white), I get a balloon-help popup with a
number of problems:
1) The first time it is displayed it is sized for two lines of text,
but contains only 1. For subsequent redisplays the frame is 1 line
high.
2) The frame is one character too narrow for the text, so I get the
continuation glyph, but the last character is not displayed on the
second line. Here's a (naive) fix:
diff --git a/balloon-help.el b/balloon-help.el
index 1fa53b4..09504c7 100755
--- a/balloon-help.el
+++ b/balloon-help.el

3) I get a very small, unkillable frame that pops up and stays around
forever. Looking at the balloon-help code, that frame is the "junk
frame", and it was created as
(make-frame '(minibuffer t
initially-unmapped t
override-redirect t ; get rid of WM decorations
width 1
height 1)))
I don't see any explicit make-frame-visible calls for that frame, but
it is used in the plist for the make-frame call for the actual
balloon-help frame:
(frame (make-frame `(initially-unmapped t
internal-border-width 0
;; try to suppress frame decorations
override-redirect t
name ,balloon-help-frame-name
border-width ,balloon-help-border-width
border-color ,balloon-help-border-color
top ,y
left ,x
popup ,junk-frame
minibuffer ,(minibuffer-window junk-frame)
width 3
height 1))))
I suspect Windows redisplay is at fault, I'll see if I can track
anything down.
4. The balloon-help frame actually has a title. I was expecting it to
just be a tooltippy kind of window. Perhaps it should be a dialog
rather than a window?
5. There appears to be a (transparent!) one pixel gap between the
bottom window border on the balloon-help frame and the text.
I'll get 21.5 compiled here, and see if it behaves any differently,
unless you'd like me to try 21.4 from CVS.
Thanks
Robert
