Hi Carlos,
In order to open a figure (let's say an input dialog box) after selecting a checkbox, you want to write the code in the callback function of that checkbox in your main GUI.
For example, here is the code in the callback function of a checkbox with the tag YourCheckbox:
%Executes on button press in checkbox.
%function YourCheckbox_Callback(hObject, eventdata, handles)
% hObject handle to YourCheckbox (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
% Hint: get(hObject,'Value') returns toggle state of YourCheckbox
if get(hObject,'Value') ==1 % if the user checks the checkbox
% Create input dialog
prompt = {'Enter a number:'};
dlg_title = 'Input';
num_lines = 1;
def = {5}; % default values
handles.YourAnswer = inputdlg(prompt,dlg_title,num_lines,def); % YourAnswer will be used in your main GUI. It's now stored in the handles structure of the GUI so you can access it in other callbacks.
guidata(hObject,handles); % update the handles structure in which you stored YourAnswer.
else
% if user unchecks the checkbox, do whatever you want.
end
So once the input dialog is closed, the variable YourAnswer is available to use in your main window.
I hope it helps you! If not please ask for more details. Now that I think of it, when you say "figure" do you mean something like a dialog box or rather another GUI?
