Hi there

I'm trying to display certain special characters in brackets in a dialog box. The common way of doing it doesn't work for me, i.e. '\theta' or whatever the character may be. I'm writing the characters in a cell array.

My code is:

prompt = {'Air Temperature [celsius]', 'Firing Angle [degrees]', 'Lattitude [degrees]'};

The text in bold above is where I cannot insert the characters necessary.

Thanks in advance.

Dialogs don't have 'Interpreter' property, unfortunately, and they're not full-blown text objects underneath. Have to hardcode the ASCII code into the string.

circ=char(176);       % dependent upon locale/system for specific character value
T=27.5;
A=23;
L=33.3;
prompt = sprintf(['Air Temperature ' circ 'C %.1f  Firing Angle %d' circ '  Lattitude %0.1f' circ],T,A,L);

Modifying the example slightly for dialog

function myprompt
  circ=char(176);
  prompt = sprintf(['Air Temperature %.1f' circ 'C   Firing Angle %d' circ '  Lattitude %0.1f' circ],27.5,23,33.3);
  d = dialog('Position',[300 300 350 150],'Name','My Dialog', ...
             'WindowStyle','normal');
  txt = uicontrol('Parent',d,...
             'Style','text',...
             'Position',[20 80 300 40],...
             'String',prompt);
  btn = uicontrol('Parent',d,...
             'Position',[130 20 70 25],...
             'String','Close',...
             'Callback','delete(gcf)');
end
