new lines from an edit text component

Hi,

I am building a small gui using GUIDE and have a multiline edit text box. I would like to consider each line seperately. Is it possible to obtain the string in the edit box as a cell array with an element for each line?

What do you mean? If you run Str=get(hObject,'String'), it's already a cell array of strings.

In r2011a I get an nxm character array.

[Fangjun Jiang]

Then would cellstr(get(hObject,'String')) be enough?

Assuming h is the handle to your uicontrol ...

s = get(h, 'string');
scell = mat2cell(s, ones(size(s, 1), 1), size(s, 2));

One only gets back a character array from a uicontrol if one initialized to a character array or character vector and does not change it afterwards.

There are an exceptions to this:

• if one created a popup or listbox from a character vector that has embedded '|' characters, then each '|' marks the end of a string, and the character vector with '|' will be converted to a cell array.

edit boxes do not break lines at '|' characters.

My recollection is that if a user edits a multi-line edit box then they will get a cell array back even if the original was a character array or character vector.

I do not recall at the moment what happens for a single-line edit box that is initialized to a character vector and then edited by the user.
