menubar Commands Hide Signature vs. mode-line

menubar Commands Hide Signature vs. mode-line

[Pavel Janík]

Hi,

menubar Commands Hide Signature in Article mode does not show/hide `s' in
the mode-line, but the signature itself is shown/hidden.

BTW - what about making these letters "active" so e.g. Mouse-2 on `s' will
toggle signature visibility? 'help-echo on this letter is nice, but that
would be nicer ;-)

Yup.  Fix in Oort Gnus v0.04.

Hm...  Do people really click around on the mode line?

I expect people to do that more and more, especially newbies.  Now
that there are nice tooltips in the mode line, and stuff...

In that case, I think it would be nice if tooltips and clickability
was added to the characters.

At present, they are generated by the `gnus-article-wash-status'
function, which just returns a string.  The mode line is updated by
`gnus-set-mode-line'.  I'm guessing that there'll have to be voodoo in
that function to add these mousey thingies?  Or what?

I don't know, but I think it is enough to just return a propertized
string (with the `help-echo' text property?).

Ah.  Cf the following node in the lispref for Emacs 21:

/----[ Properties in the Mode Line ]
| 
| Properties in the Mode Line
| ---------------------------
| 
|    Starting in Emacs 21, certain text properties are meaningful in the
| mode line.  The `face' property affects the appearance of text; the
| `help-echo' property associate help strings with the text, and
| `local-map' can make the text mouse-sensitive.
| 
|    There are three ways to specify text properties for text in the mode
| line:
| 
|   1. Put a string with the `local-map' property directly into the
|      mode-line data structure.
| 
|   2. Put a `local-map' property on a mode-line %-construct such as
|      `%12b'; then the expansion of the %-construct will have that same
|      text property.
| 
|   3. Use a list containing `:eval FORM' in the mode-line data
|      structure, and make FORM evaluate to a string that has a
|      `local-map' property.
| 
|    You use the `local-map' property to specify a keymap.  Like any
| keymap, it can bind character keys and function keys; but that has no
| effect, since it is impossible to move point into the mode line.  This
| keymap can only take real effect for mouse clicks.

That would be a very convenient way of doing it -- then the
`gnus-article-wash-status' could just return a string with the
required text props set.

That would be the way to do it, then.

I don't mouse much, so could someone else implement this?

I added the tooptip properties to the string some month ago (it is in
CVS Gnus), and it worked fine.  At the same time, I also tried adding
the mouse properties, but got no effect.

It is very easy in GNU Emacs - look at the function propertize and how it
is used. Just put 'local-map property on these characters along with
current 'help-echo and you are done.
