Re: Mouse highlighting occurs only after movements

[Richard Stallman]

    Had this in Gnus: if the mouse pointer is in a screen position where
    mouse highlighting would occur when the Gnus Summary buffer gets
    updated after a Gnus command, after the update the line which happened
    to pop up with the mouse highlit area right under the mouse pointer is
    not getting the mouse highlighting (only after the mouse pointer
    moves).

I seem to recall adding a feature like that.
People asked for it.

      The crazy thing is that if the cursor is blinking in the
    should-be-highlighted-but-is-not-yet area, it is blinking in green,
    while the rest of the line still looks ordinary B&W.

I wonder if the code that redisplays the cursor checks the properties
rather than the status of mouse highlighting.  Can someone check that?

Yes, I changed it so that setting `mouse-highlight' to 1 causes the
mouse highlight to be shown only after actually moving the mouse.

It seems that if you place the mouse over a mouse sensitive area
(which then gets highlighted), you then move the cursor (so the
highlight disappears), and then moves the cursor into the mouse
sensitive area, the characters that you move over gets highlighed with
the mouse-highlight face.  The blinking cursor anomaly is a special
case of this...

I don't think it a big issue though; it only happens when the cursor
is moved with the keyboard into a mouse-sensitive area which the mouse
happens to be hoovering over.

Anyway, it is definitely an error in my original implementation --
I'll see if I can find a suitable fix...

I just committed changes to the x, w32, msdos, and mac ports to fix this.

However, I noticed the that mouse-highlight functionality isn't
implemented on the MAC port!  To add, look at the treatment of
Vmouse_highlight in xterm.c or w32term.c for details.
