Re: Matlab menu-driven code - problem

[Lester Anderson]

Hi Ben

I have run the command as suggested but still get a blank figure window, not as you show. Am I missing something in the installation - no error when I ran the following - straight start of Octave and move to the script folder:

Hello all,

I have some Matlab code that computes a number of geophysical/flexural parameters and should plot the data out. However, the front-end code to the functions does not do anything other than generate a blank figure window: The code below is the top level program that calls the function from the HM_ variables

%program flex2d

%defining variables

global flagelas
global flagtyp
global flaggeom
global flaghede
global flagsol
global flagfig


flagelas=0;
flagtyp=0;
flaggeom=0;
flaghede=0;
flagsol=0;
flagfig=0;

%setting the graphical user interface

canvas = figure('Name','FLEX2D');  <------ this works and the figure window opens, then that is it !

%------------------------------------------------------------------------

HM_par = uimenu(gcf,'Label','Parameters');
HM_parmec = uimenu(HM_par,'Label','Elastic properties', 'Callback', 'elas');
HM_parana = uimenu(HM_par,'Label','Type of analysis','Callback','tanal');

HM_geom = uimenu(gcf,'Label','Geometry');
HM_geomlo = uimenu(HM_geom,'Label','Load geometry','Callback','geom');
HM_geomde = uimenu(HM_geom,'Label','Heights and Densities of loads','Callback','hdens');
HM_geomfi = uimenu(HM_geom,'Label','Read loads from file','Callback','refile');

HM_sol = uimenu(gcf,'Label','Analytical Solution');
HM_solbe = uimenu(HM_sol,'Label','Solve','Callback','solbeams');
HM_solres = uimenu(HM_sol,'Label','Model Results','Callback','results');

HM_plot = uimenu(gcf,'Label','Plot');
HM_plotin = uimenu(HM_plot,'Label','Undeformed Topography','Callback','undef');
HM_plotout = uimenu(HM_plot,'Label','Deformed Topography','Callback','defor');


HM_help = uimenu(gcf,'Label','Help');
HM_helpab = uimenu(HM_help,'Label','About Flex2d','Callback','boxabout');
HM_helpbox = uimenu(HM_help,'Label','Help','Callback','boxhelp');

%-----------------------------------------------------------------------------

All the highlighted function in bold exist in the run folder so that is not the problem (yet)

All of the HM_xxx have attributed values, so I assume it is actually doing something. But the calls to the functions in the uimenu are not run/active. Is there anything wrong or is there a different methodolgy to follow for Octave?

Cheers

Lester

maybe a silly thing, but in the octave help, the keywords 'label' and 'callback' are lowercase. can anyone comment on whether such thing case sensitive in octave?

Property names (in the graphics system) are not case-sensitive.
