Hi people,

I have some gui program in matlab. I create some pictures. Then I want to do profile on the pictures. I created push button, say "Manual profile". I push this button and then I want to program to wait until I will select between some pictures I already created.

function pushbutton15_Callback(hObject, eventdata, handles) %(manual profile button)
% hObject    handle to pushbutton15 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
%? what should be here?
% Here I want to wait until I select some picture

Then my purpose is to get handle to the selected figure and pass it to the function of improfile. In that way I want to create the profile on selected picture.

Thank you very much.

You could add a button "Select this" to all open figures:

function pushbutton15_Callback(hObject, eventdata, handles)
openFig = get(groot, 'Children');
hButton = gobjects(1, numel(openFig));
hFig    = ancestor(hObject, 'Figure');
for k = 1:numel(openFig)
   hButton(k) = uicontrol(openFig(k), 'Style', 'PushButton', ...
       'String', 'Select', ...
       'Callback', {@selectBtn_Callback, handles, hFig});
end
setappdata(hFig, 'SelectButton', hButton);
end
function selectBtn_Callback(hObject, eventdata, handles, hFig)
hSelectedFigure = ancestor(hObject, 'Figure');
hButton = getappdata(hFig, 'SelectButton');
delete(hButton);
setappdata(hFig, 'SelectButton', []);
... do with hSelectedFigure what you want now
end
