Hello,
this is the second version of an uimenu implementation for the fltk backend. It
should be compatible with matlab in most cases. My first implementation was
more or less a proof-of-concept, this one is more careful designed. (I don't
claim to be good C++ programmer, so if you think something should be done
differently, I am open for suggestions)
This time I have separated the uimenu functions from the plot_window in a
different class. Keep in mind that not all menu properties in fltk can be
changed dynamically, therefore I have to rebuild the entrire menu in some cases.
I have attached a Changeset relative to the current tip. Changelog, News entry
and manual entry are not included yet.
Since I have seen some crashes in intermediate versions, it would be nice if
people regularly bulding octave on Mac and Windows could test the changeset. I
have attached a simple test file as well.

Please not that there is already a bug opened for the delayed output of a
callback function.
https://savannah.gnu.org/bugs/?31121
<simple_menu.m><Changeset.uimenu_ver2>
This simple demo crashes octave.
figure (1)
clf
plot (1:10)
f = uimenu ("label", "foobar");
uimenu (f, "label", "Say Hello", "Callback", "disp ('Hello World')");
uimenu (f, "label", "Clear Figure", "Callback", @clf);
The first menu item illustrates the problem with the delayed output.
Clicking on "Clear Figure", causes a core-dump
octave:1> backend_fltk
error: `backend_fltk' undefined near line 1 column 1
octave:1> backend fltk
octave:2> demo_uimenu

-- Function File: clf (HFIG)
-- Function File: clf (HFIG, "reset")
