MATLAB: Configure GUI listbox to initially have no selections

guilistbox

When I populate a listbox with a list of filenames, the first string in the list is always highlighted. I want it so nothing is selected upon initial loading.

I use:

set(handles.files, 'String', handles.list_names,'Value',0)

handles.files is the listbox, and handles.list_names are the strings that will be put in the listbox. I added the 'Value',0 part, but then I get the error:

Warning: multi-selection listbox control requires that Value be an integer within String range Control will not be rendered until all of its parameter values are valid

Any ideas?

I do not see any mechanism for this.

When I need to do something like this, I usually add a header line such as 'Choose File' as the first string (the one that gets highlighted), and then I program my functions to know that value 1 means nothing selected.

MATLAB: Initially Disabled Button Group when using GUI / GUIDE

I figured it out. There isn't any default disablement of the Button Group - it needs to be coded into the disabled position at the beginning of the code under the _OpeningFcn function. Here is the code:

function MattsTestScript_OpeningFcn(hObject, eventdata, handles, varargin) % Default line produced by GUIDE


handles.output = hObject;  % Default line produced by GUIDE
guidata(hObject, handles);  % Default line produced by GUIDE
set(findall(handles.MattsButtonGroup, '-property', 'enable'), 'enable', 'off'); % HERE IT IS

MATLAB: How to create a popup mesage initially before program running

Here's one way to do it, popupgui is the name of the GUI I used to create the code, this was created with the help of GUIDE, it will ask for the user name and if the user doesn't provide one or cancels the dialog the GUI will give an error and close it self, handles.UserName can be used in any other GUI function to do something with the name the user inserted, the name is just a string.

function popupgui_OpeningFcn(hObject, eventdata, handles, varargin)
% This function has no output args, see OutputFcn.
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
% varargin   command line arguments to popupgui (see VARARGIN)
% Choose default command line output for popupgui
handles.output = hObject;
prompt = {'Please write your name'}; %what the user must do
dlg_title = 'User Login'; %the title of the dialog
num_lines = 1;  %the number of lines that can be inserte
def = {''}; %this is the default name
UserName = inputdlg(prompt,dlg_title,num_lines,def); %the diaglog
if cellfun('isempty',UserName)
uiwait(errordlg('You must insert your name','Program terminated'))
error('You must insert your name')
end
if isempty(UserName)
uiwait(errordlg('You canceled the dialog','Program terminated'))
error('You canceled the dialog')
end
%convert cell to just a string and save it to the handles struct
handles.UserName=cell2mat(UserName); %so it can be used elsewhere
% Update handles structure
guidata(hObject, handles);
