I have created a GUI in which there is an editbox where user enters certain text. This text is then required to be added in a report which is generated at a later stage. I am using a code which is something like this:

%%Code to get text entered in editbox
  handles.text=get(handles.editbox,'string');
%%Code to add text to matlab report (via DOM API)
  text_to_be_added=Paragraph(handles.text);
  append(report,text_to_be_added);

Now my problem is as long as the text entered in editbox is a single line the result is fine (Text is copied as it is from editbox to report). But if I add a new line in the text which is to be entered in editbox (by pressing enter key), the text which is printed in report is totally disoriented.

Eg: If the text in edit box is: This month is july. Then the text saved in my report is: This month is july.

But if the text in edit box is:

This month is

july.

Then the text saved in report looks like this:

Tjhuilsy .m o n t h i s

Is their any way this problem can be fixed. I know adding '\n' rather than pressing enter key will add a new line in report but is their any other way in which matlab can recognize enter key press to add a new line automatically.

Are you sure, you can enter the data in multiple lines in single editbox ? I guess Its not possible... Single edit box is not allow to enter the data in multiple lines.. Please confirm this..

Shameer - Yes, multiple lines of text can be entered into an edit text box (so long as the Max property is greater than the Min property).

Sudhanshu - you mention that typing \n works. Can you perhaps inject this character after the user has typed in the text into the edit box? Note that

handles.text=get(handles.editbox,'string');

will be a cell array of strings, one for each line in the edit box. So you could create a single line string from these multiple strings, concatenating each together and separating each by a \n. For example,

 strData = get(handles.edit1,'String');
 handles.text = strData{1};
 if size(strData,1) > 1
   for k=2:size(strData,1)
      handles.text = [handles.text  '\n' strData{k}];
   end
 end

However, I don't know if this will be sufficient when adding it your report.

Thanks a lot Geoff. Your approach works like a charm. The code needed minor tweaks.

 strData = get(handles.edit1,'String');
 handles.text = strData(1,:);
 if size(strData,1) > 1
   for k=2:size(strData,1)
      handles.text = [handles.text  '\n' strData(k,:)];
   end
 end
