hs-minor-mode: hs-mouse-toggle-hiding

[Peter Meier]

Hi all,

I want to use Emacs as editor for Programming C and C++.

I'd like to use hs-minor-mode for hiding some C blocks.
Now I've a problem with hs-mouse-toggle-hiding.
If I hide a block by clicking on it, I'm not able to get it back.
Where must I place the click to get the block back?

Thanks
    Peter

You should click on the "..." that replaces the hidden block.  If that
doesn't work in some case, please report that as a bug.

recent hideshow.el[*] allows you to futz w/ the overlay (and its
properties) at creation time via user var `hs-set-up-overlay'.

here are some ideas:
 - reposition overlay start to beginning of line
 - add an overlay or text-property to the fragment of text
   between the block start and the overlay that "slides" the
   mouse click to end of line
 - advise `hs-mouse-toggle-hiding' to check end of line
 - put marker or otherwise record location of block start
   and advise `hs-mouse-toggle-hiding' to check for it

i can't evaluate the merit (if any) of these ideas, since i don't use
the mouse personally (probably this is evident in the implementation of
`hs-mouse-toggle-hiding').  small hacks to facilitate mouse handling,
for inclusion in the Commentary, welcome.

Does any of these do the obvious thing--let the click on the ellipsis
that replaces the hidden block unhide it?  If one of these does that,
I'd suggest to make it the default.  If not, add such a behavior and
make it the default.  That's the behavior I'd expect.

IIRC you can't do that right now.  Just like you can't put a mouse-face on
them either.
