How to repeat the content of a listbox in gui matlab?

Hello,

In my code, I have an edit box where the user has to enter a value in this edit box, afterward this entered value is transferred to a list box. My list box has to be populated with many rows and one column, say 1000 rows. So, what I need is to repeat the printed value from the edit box 1000 times. Is there a way for doing this?

I get the data from my edit box as:

data=get(handles.edit_T,'string');

Then to transfer it to the list box I have:

data=[data ; cellstr('')];
set(handles.edit_Texp,'string', data);

I tried to use a 'for' loop like:

for i=1:1000
    data=[data ; cellstr(i)];
set(handles.edit_Texp,'string', data);
end

But the first line in the listbox is correct and after that it shows '2'

Would someone tell me how to do this?

Thanks in advance,

Ahmed

Maybe you mean:

data = get(handles.edit_T,'string');
data = cellstr(data);
set(handles.edit_Texp, 'string', repmat(data, 1000, 1));

cellstr(i) converts i to a cell string. Setting the String property 1000 times is a waste of time.

One more question. I am trying to read the first column of a text file and print it in a list box (tauexp) by using:

[filename pathname] = uigetfile('*.txt', 'File Selector]');
fullpathname=strcat(pathname , filename);
x = fileread(fullpathname);
tScan = textscan(x, '%s  %f  %s','headerlines',1);
newScan = tScan{:};
data=newScan(:,1); % to read only the 1st column
set(handles.edit_tauexp,'string',data);

What I got is a mixture of data in the first column with the data in the 4th column. Could you please tell me why and how to fix this?
