Is this with QtHandles or with fltk?

I am not sure what Mathious did, I will let him say what he did.

when I tried it I got:

>> graphics_toolkit qt

>> demo uimenu

uimenu example 1:

 clf;

 surfl (peaks);

 colormap (copper (64));

 shading ('interp');

 f = uimenu ('label', '&File', 'accelerator', 'f');

 e = uimenu ('label', '&Edit', 'accelerator', 'e');

 uimenu (f, 'label', 'Close', 'accelerator', 'q', 'callback', 'close (gcf)');

 uimenu (e, 'label', 'Toggle &Grid', 'accelerator', 'g', 'callback', 'grid (gca)');

uimenu example 1: failed

A(I,J,...): index to dimension 1 out of bounds; value 61 out of bound 1

>> diary off

and I got the surface drawn in a qt window but there were no menus that i can see.

What's actually failing is the call "surfl(peaks)". If you try that alone, you get:

octave-qt:1> surfl(peaks)

error: surfl: A(I,J,...): index to dimension 1 out of bounds; value 61 out of bound 1

error: called from:

error:   /opt/sw/octave-classdef/share/octave/3.7.5/m/plot/surfl.m at line 135, column 5

Michael.

I replaced the 3 line that were related to surfl with a one liner sombrero

I now get no errors but I still don't get any menu.

I do get a qt plot window but only the rotate   and   zoom controls work,

the zoom out does not work and the pointer does not work.

This was true also before i changed to sombrero.
