Using a pushbutton in MATLAB GUI as a button to continue?

Hi, I have 2 pushbuttons. With one of them I call a specific function. eg: Main_function(...,...,...).

Now within this Main_function at some points I need the user to press continue. (The user has to change some equipment then continue the work) Previously I used input('') and the user should have just push enter or whatever to continue the function.

Right now I want the second pushbutton to do this, but I don't know how.

my idea was to put a loop like this:

push=0

while push==0

puase(0.1);

end and pushing the button change the push=1, but I can't do that.

Note that I have access to the handles in the called function.

Add a while loop with nothing inside:

while (~push)
% do nothing until push == 1. Push has to be global, it changes when the pushbutton is pushed
end

I would not do it like either of you. I think the best way, and what I usually see as recommended, is to wrap a call to msgbox in uiwait. Like this:

uiwait(msgbox('Now, change the equipment, then click OK to continue'));

You can do what I do, and that is to make a separate function called msgboxw (in a separate msgboxw.m file somewhere on your path) and then just call that instead of msgbox:

function msgboxw(message)
uiwait(msgbox(message));

To use

msgboxw('Click OK to continue');

Or, to give the user more flexibility,

promptMessage = sprintf('Do you want to Continue processing,\nor Cancel to abort processing?');
titleBarCaption = 'Continue?';
button = questdlg(promptMessage, titleBarCaption, 'Continue', 'Cancel', 'Continue');
if strcmpi(button, 'Cancel')
  return; % or break, if you're in a loop
end

This has the same effect as msgboxw() except that it allows the user to bail out if they want.
