How to change QUESTDLG code in order to make it 'normal'?

Hi! I would like to interact with other windows before responding to questdlg.

Where I can see the Matlab code of that function?

Thank you in advance.

Hi,

The function "questdlg" is designed to be "modal" i.e. it will prevent the user from interacting with other MATLAB windows before responding.

As a workaround you can create a utility based on the function "dialog". Here you can change the "WindowStyle" property to "normal" for your usecase. Below is an example to use it:

function answer = askUser(q,title,buttons,default)
    if nargin<2,  title    = 'Question'; end
    if nargin<3,  buttons  = {'Yes' 'No'}; end
    if nargin<4,  default  = buttons{1}; end

    d = dialog('Name',title,'WindowStyle','normal');     % modaless!
    uicontrol(d,'Style','text','String',q,...
                 'Units','normalized','Position',[.05 .55 .9 .35]);

    y = numel(buttons);
    for k = 1:y
        uicontrol(d,'Style','pushbutton','String',buttons{k}, ...
                     'Units','normalized','Position', ...
                     [.1+.8*(k-1)/y  .1  .8/y-.05  .25], ...
                     'Callback',@(b,~)setappdata(d,'Answer',buttons{k}));
    end
end

You can then call this utility to create your own custom dialog box.

Refer to this documentation for more information on "dialog" :

Hope this helps!
