MATLAB: Message window in GUI (MatLab)

command window in guiconsole windowedit1message in gui

Hello. I am trying to create a text window in GUI that will be used to display messages/current activity of the program. It should be similar to the Command Window of matlab. That is, when I want to output some message, the message should appear in my text window of the GUI, not in the Command Window. Also, the text window will be used only for output, so no input will be preformed. I use the 'edittext' component as follows:

set(handles.edit1,'String','My message' );

however, next time when I want to output a new message, I want the old message to be present in the message box as well. That is, my message box should accumulate all the messages over time (or at least several most recent strings) just like Command Window or any console window does.

Thank you

oldmsgs = cellstr(get(handles.edit1,'String'));
set(handles.edit1,'String',[oldmsgs;{'My message'}] );

And be sure to set the edit box to 'Enable', 'disable'.

I thought I wrote about this topic just about a week ago, but I cannot seem to find that message.

Automatically position the scroll bar to any particular position in the edit list box requires resorting to the Java level.

MATLAB: Is the string property of the Edit UIControl empty in the KeyPressFcn callback (GUIDE)

This issue stems from the way Edit UIControls work in GUIDE. The 'string' property of this object is not modified until either a) the user presses 'enter' or b) the user switches focus away from the Edit box (placing a breakpoint caused the focus to switch to the MATLAB Command Window, which is why you are only seeing the 'string' property update only with the breakpoint).

If you need this property to update without hitting 'enter' or switching focus, the best way to work around this is to use the 'eventdata' argument to the 'KeyPressFcn'. From 'eventdata', you can extract the key that was pressed and add it to a persistent character array.

First, create the string in the CreateFcn for your Edit control:

handles.searchString = '';
guidata(hObject, handles);

Second, add the following code to the front of your KeyPressFcn:

% --- Executes on key press with focus on edit1
function edit1_KeyPressFcn(hObject, eventdata, handles)
% if backspace, delete last character in the search string
if strcmp(eventdata.Key, 'backspace')
    handles.searchString(end) = [];
    guidata(hObject, handles);
% else, add the key that was pressed to the search string
else
    keyPressed = eventdata.Character;
    handles.searchString = [handles.searchString keyPressed]
    guidata(hObject, handles);
end
handles.searchString
% your code goes here
