Stop permanently execution of codes under a Callback using another Callback

9 visualizaciones (últimos 30 días)
Hi there.. I have a GUI with a 'Compute' pushbutton and a 'Stop Calculation' pushbutton. I would like to know how can I stop (not interrupting temporarily) the execution of codes which come under 'Compute' button immediately after clicking 'Stop Calculation' button without completing the remaining codes. I am attaching the demo of codes associated with the 'Compute' button here. What will be the additional codes I have to add to the 'Compute' as well as 'Stop Calculation' button in order to achieve this task? Looking forward for a help on this. Thanks in advance!
function pushbutton3_Callback(hObject, eventdata, handles) %Compute
%---------------If Auto run mode is on-------------------
if(get(handles.radiobutton1,'Value')==1)
% certain lines of code
tstart=tic; tstop=0;
if(isnan(a))
a=inf;
end
while(((~(get(handles.radiobutton1,'Value')))||tstop<a*60) && getappdata(handles.pushbutton13,'Value')==1)
h = waitbar(0,'computing');
if (get(handles.radiobutton8,'Value')==1)
% certain lines of code
end
waitbar(0.1,h,'computing');
if (get(handles.radiobutton9,'Value')==1)
% certain lines of code
end
waitbar(0.2,h,'computing');
if (get(handles.radiobutton10,'Value')==1)
% certain lines of code
end
waitbar(0.3,h,'computing');
if(get(handles.radiobutton3,'Value')==1)
% certain lines of code
end
waitbar(0.5,h,'computing');
if(get(handles.radiobutton4,'Value')==1)
% certain lines of code
end
waitbar(0.7,h,'computing');
if(get(handles.radiobutton5,'Value')==1)
% certain lines of code
end
waitbar(0.9,h,'computing');
if(get(handles.radiobutton6,'Value')==1)
% certain lines of code
end
waitbar(1,h,'computing');
end
else
%---------------If Autorun mode is not on--------------
h = waitbar(0,'computing');
if (get(handles.radiobutton8,'Value')==1)
% certain lines of code
end
waitbar(0.1,h,'computing');
if (get(handles.radiobutton9,'Value')==1)
% certain lines of code
end
waitbar(0.2,h,'computing');
if (get(handles.radiobutton10,'Value')==1)
% certain lines of code
end
waitbar(0.3,h,'computing');
if(get(handles.radiobutton3,'Value')==1)
% certain lines of code
end
waitbar(0.5,h,'computing');
if(get(handles.radiobutton4,'Value')==1)
% certain lines of code
end
waitbar(0.7,h,'computing');
if(get(handles.radiobutton5,'Value')==1)
% certain lines of code
end
waitbar(0.9,h,'computing');
if(get(handles.radiobutton6,'Value')==1)
% certain lines of code
end
waitbar(1,h,'computing');
close(h)
h = msgbox('Computation Done');
end

I was able to work cause a slider control to stop executing with a pushbutton which changes a variable. The variable value then causes another portion of a if statement to execute which does not include the slider. Code below the slide can then execute without the slider serving any further purpose. I am sharing because I found that this is simpler than some other solution out there although it's still probably not that elegant. Please note that this was done through a LOT of trial and error, so some of the code may be unnecessary or redundant (I didn't have time to clean it up yet).
