Trouble With GUI Button
1 次查看(过去 30 天)
显示 更早的评论
I'm trying to set up a function that I can use to take a snapshot of something I work on before and after by pushing a button. Later I'm going to add something to append them together. My problem seems to be that I can only execute the print command once. I think it might be because it won't save over the new .ps file that I'm creating. I've tried the filename command to rename the files, but it doesn't seem to work. Also, I am having troubles changing the string of the button each time it is pushed. This is the section of code I'm having troubles with:
% --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
count = 0
pushed = get(hObject, 'Value');
if count = 0
filename = 'Before.ps';
print('-dps','-s',gcs, filename);
count = 1;
set(hObject, 'String', 'After') ;
else
filename = 'After.ps';
print('-dps','-s',gcs, filename);
count = 0;
set(hObject, 'String', 'Before') ;
end

Make count global or persistent.
