bug#72791: 29.4; x-popup-menu in emacs built with lucid xtoolkit can't scroll

[Thierry Volpiatto]

Hello,

when Emacs is built with "--with-x-toolkit=lucid" a menu displayed by
x-popup-menu and larger than (window-height) doesn't have a scroll bar.
The part which is shown is the center part (first lines and last lines
doesn't appear).  This doesn't happen with a default build (gtk).

I don't know if it is a misfeature of Lucid or an emacs bug.

Thanks.

lwlib doesn't support this feature.  I suggest building with Motif.

Thanks for the info, it is what I wanted to know.

> I suggest building with Motif.

Motif seems to have the same problem, quite different though, the
beginning of text is shown (title and next candidates) but the end is
not shown (normal it is out of screen) and we can't scroll further,
only gtk allow moving up and down in the list of candidates.
As with lwlib, I guess it is not supported by motif and out of emacs scope.

OK, but why (window-height)?  Is the intent to the frame height, or
the height of the screen, perhaps?  I don't understand why the height
of the menu should be limited by the window.

Yes, you are right, I meant the height of the screen.

OK, thanks.

I've added a PROBLEMS entry about this, and I think we should close
this bug with that.

Which menu was too long?  Is it a menu generated by a core Emacs
feature or by 3rd-party package?

A menu in Helm, screenshots attached, the first is with Lucid and the
other with Gtk.

Given this limitation of Lucid, my suggestion would be to organize the
menu into a multilevel menu by grouping related items, to make the
top-level menu shorter.

Didn't know it was even possible, I will try this, thanks.
