Thread: help with MATLAB questdlg loop

Hi,

I wrote a function that draws regions on an image, now I'm really stuck on creating a loop out of the message box that appears, asking if the user wants to draw another one, redo the previous or stop drawing.

Here is the basic framework of the relevant bit:

i=1
%insert function stuff

button=questdlg('Add region?',...
'Add',...
'Yes','Redo prev','No','Yes');


while strcmp(button,'Yes')

i=i+1
%stuff

button=questdlg('Add region?',...
'Add',...
'Yes','Redo prev','No','Yes');

end


while strcmp(button,'Redo prev')

%stuff, overwrites current i

button=questdlg('Add region?',...
'Add',...
'Yes','Redo prev','No','Yes');

end


while strcmp(button,'No')

%stops

end

I don't think it can go back to the first while 'Yes' after the 'Redo Prev' while. Is there a better way to do this?

Thanks for reading...and any pointers at all would be a great help..

Err problem solved, mods can delete this thread.
