extracting info from edit text gui

[EDIT: 20110625 - reformat - WDR]

Please help me with this

function [] = clear_edit_example()
% Show how to clear and editbox string when cursor is placed over it.

S.fh = figure('units','pixels',...
              'position',[500 500 300 50],...
              'menubar','none',...
              'numbertitle','off',...
              'name','clear_edit_example',...
              'resize','off');
S.ed = uicontrol('style','edit',...
                 'units','pixels',...
                 'position',[10 10 280 30],...
                 'fontsize',14,...
                 'string','Enter Value');
set(S.fh,'windowbuttonmotionfcn',{@fh_bmfcn,S})

To extract the data (text) from the edit box, you will need something more or less like this:

% Get the string from the editText box.
myText = get(S.ed, 'String');

EDIT

When you run a GUI, the variables' scope is only within the GUI. If you want to be able to manipulate that variable later, save the variable into a .mat file and load it later. For example:

% Get the string.
myText = get(S.ed, 'String');

% Save the variable into a .mat file.
save('myTextVariable', 'myText');

Later, to recover it:

% Load the variable for later use.
load('myTextVariable', 'myText');

Try it and let me know if it works ;-)

inside the function the value works fine... but when i check in the matlab prompt.. it shows 'text' is undefined variable..
