MATLAB: [gui] how to load data

editgui

i want load data from workspace

i think that

set(handles.e_hole_1_min,'string','gui_H_size')

but do not working…

Best Answer

Try using num2str to convert the number to a string:

set(handles.e_hole_1_min, 'String', num2str(gui_H_size));

or with recent versions:

handles.e_hole_1_min.String = num2str(gui_H_size);

If that doesn't work, actually even if it does, read this.

mec123 - you can set default values in the OpeningFcn of your GUI. Just do

 set(handles.checkbox8,'Value',1);

to set the checkbox as checked and

 set(handles.checkbox8,'Value',0);

to set the checkbox as unchecked.

Also, there is no need to use global variables. If you want one callback to access the values of the other controls, then use the handles structure as

 function pushbutton1_Callback(hObject, eventdata, handles)
 if get(handles.checkbox7,'Value') == 0
     % do action 1

 end
 if get(handles.checkbox8,'Value') == 0
     % do action 1
 end

MATLAB: [GUI] Update variable in while loop

If you want any values of handles to change inside that loop because of something that you did in another callback then you will have to explicitly obtain handles again on each loop iteration:

while ...
    handles = guidata(hObject);
    ...
end

One copy of handles does is not shared between all callbacks: each time you change it within a callback it will create a copy local to that callback. It is only when you store that copy (using guidata) that it will be stored in the parent figure... and only then can you get the updated handles structure (either by triggering a callback, or calling handles=guidata(...)).

Or you could avoid this entire mess by writing your own GUI and using nested functions.
