MATLAB: Problems running .fig file

guiguide

Hi,

I recently made a gui for manually scanning images and annotating them. It was running Ok (i.e from guide or openfig). I had done some initializations in the opening_fcn. But for some reason now when a try to open it, the initialization do not occur (i put in test strings in it) and the gui is giving me error because of undefined variables. I tried running on another machine, the same problem. If I run in debug mode then it goes through the opening_fcn and displays the string. I don't understand whats going on ??

please help

Paulo's guess about you having renamed something is reasonable. I would, however, first suspect something more simple.

You cannot run a .fig file by opening it or using openfig. You must run the gui program by name; it will open the .fig file.

MATLAB: Callback errors when saving GUI under new name (using GUIDE)

Sorry if this is a dumb suggestion, but have you searched for the string 'DataViewer1' in the DataViewer2 mfile? I seem to remember having a problem with GUIDE not recognizing everything it had to change. That wouldn't show up in the text compare. You might also bring up the property inspector for the control in GUIDE and see if there's anything funny in the 'CreateFcn' field.

Anyway, as the default commenting notes, 'handles' isn't defined until all the CreateFcns have run, so it should be empty at your breakpoint. I think the real puzzle is why DataViewer1 doesn't throw an error! So you might try to figure out when 'handles' is being defined in DV1, by putting similar breakpoints in each of the CreateFcns. As a general rule, it may be safer to put the initialization lines in the OpeningFcn, where 'handles' is sure to be defined.

If you don't figure out the problem, perhaps you could post the full code.

MATLAB: Use a push button to close the GUI

Use the close request function

https://www.mathworks.com/help/matlab/ref/closereq.html

function pushbutton5_Callback(hObject, eventdata, handles)
closereq(); 
end

Only use gcf() or gca() when there is no other possible way to get the handle to a figure. For GUIDE GUIs, you can get the handle to the figure from the handles input (example: handles.figure1).
