Date: Mon, 18 Jun 2018 15:24:17 -0300

[Message part 1 (text/plain, inline)]

In all tooltips I get the crossed circle icon (don't know its stock
name) at the left. I don't know if this is the intended behavior but it
surely looks weird and the icon is both confusing and
unnecessary. Please look at the attached screenshot.

Searching through the icon browser I would say that the icon in the
screenshot has stock name action-unavailable or
action-unavailable-symbolic. I grepped emacs code for these names and
couldn't find them, so I assume they're set by gtk on response to a
requested "unavailable action" (go figure). Now, the gtk code that
creates the tooltip seems to be replacing the original icon+label box
with just a custom label:

  0       g_object_set (G_OBJECT (widget), "has-tooltip", FALSE, NULL);
  1       x->ttip_widget = tooltip;
  2       g_object_ref (G_OBJECT (tooltip));
  3       x->ttip_lbl = gtk_label_new ("");
  4       g_object_ref (G_OBJECT (x->ttip_lbl));
  5       gtk_tooltip_set_custom (tooltip, x->ttip_lbl);
  6       x->ttip_window = GTK_WINDOW (gtk_widget_get_toplevel (x->ttip_lbl));

I'm unable to see here how an icon is being set at all.

This was a hard one to find...

The problem is in gtkutil.c xg_show_tooltip: gtk_widget_show_all makes
the icon that comes by default with a tooltip visible, which is
undesirable since that icon was never set. The fix is to simply use
gtk_widget_show.

Attached is a python script that reproduces the behavior, trying to
mimic the real emacs code. The first time you press the button show is
called and the tooltip has no icon, as expected. The second time
show_all is called and the missing icon problem manifests. If you keep
pressing the button show and show_all alternate, but the missing icon
is still there since it has been made visible forever by the first
show_all call.

That is sure to be useful, but I don't think it's a patch.  Did you mean
to post one?

It's just that it was so easy that I described it in words: change
show_all to show :). But ok, here I'm attaching a proper patch.

Thanks, I checked it out on my gtk build; I don't have quite the same
icon you showed, but it looks like some kind of place holder that
shouldn't be there indeed.  The patch gets rid of it, so I guess it's
the right thing.

Have you done copyright assignment for Emacs?  Obviously, the patch is
too trivial to require it, but in case you haven't done it we should
mark the commit with "Copyright-paperwork-exempt: yes".

Different stock icons for "missing icon" I guess.

It's an icon gtk puts by default in a tooltip widget. Usually it's hidden
if you don't set it but show_all is exposing it. The attached python script
shows all this very clearly.
