Ignore mouse bindings on the title bar

Binary i3 version:  4.12 (2016-03-06, branch "4.12") © 2009 Michael Stapelberg and contributors

URL to a logfile as per http://i3wm.org/docs/debugging.html:
Doesn't apply.

What I did:
Bindings to focus windows with the mouse wheel.

bindsym --release --border --whole-window button4 focus
bindsym --release --border --whole-window button5 focus

What I saw:
The bindings apply even to the title bar.

What I expected instead:
An option to ignore the bindings on the title bar so that I can scroll through stacked windows.

I don’t see a link to logs.i3wm.org. Did you follow http://i3wm.org/docs/debugging.html? (In case you actually provided a link to a logfile, please ignore me.)

Have you tried not adding --border?

[9ary]

Ah yes, I have, forgot to mention it. Same problem.

Edit: Never mind what I wrote here before.

This should be the relevant code (src/click.c). The comment says it all:

       /* clicks over a window decoration will always trigger the binding and
           * clicks on the inside of the window will only trigger a binding if
           * the --whole-window flag was given for the binding. */
          if (bind && ((dest == CLICK_DECORATION || bind->whole_window) ||
                       (dest == CLICK_BORDER && bind->border))) {

Edit: This logic seems to be broken already in an unrelated manner as well. I'll open a bug for this.

OK, back to the proposal. I think this makes sense and would be OK adding another flag for this. The only not-so-nice thing is that to preserve compatibility, we're forced to have it be a --exclude-titlebar flag, i.e., with inverted meaning compared to --whole-window and --border.

@stapelberg What are your thoughts?

Sorry for the late reply. I think adding --exclude-titlebar sounds good.
