Use multiple gui and get data from another gui function in matlab - matlab

Question

I want to create a gui program with matlab but i want to use multiple gui. for example I have the main gui function and I want to get data from another gui with edit textbox. In the example below, I want to return the p variable to the main gui.
THE MAIN GUI:
function varargout = FoProgram(varargin)
gui_Singleton = 0;
gui_State = struct('gui_Name', mfilename, ...
'gui_Singleton', gui_Singleton, ...
'gui_OpeningFcn', #FoProgram_OpeningFcn, ...
'gui_OutputFcn', #FoProgram_OutputFcn, ...
'gui_LayoutFcn', [] , ...
'gui_Callback', []);
if nargin && ischar(varargin{1})
gui_State.gui_Callback = str2func(varargin{1});
end
if nargout
[varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});
else
gui_mainfcn(gui_State, varargin{:});
end
function FoProgram_OpeningFcn(hObject, eventdata, handles, varargin)
handles.output = hObject;
guidata(hObject, handles);
function varargout = FoProgram_OutputFcn(hObject, eventdata, handles)
varargout{1} = handles.output;
function labor_2_Callback(hObject, eventdata, handles)
function fel1_Callback(hObject, eventdata, handles)
cla reset;
clc;
clear all;
n = guzu() %Here I call the second Gui function with edit textbox
uiwait(gcf);
x=linspace(-3*pi,3*pi,1000);
y=sin(x);
plot(x,y,'k','LineWidth',4)
sz='ymcrgbkymcrgbkymcrgbkymcrgbk';
hold on
title('Sin(x) Taylor sora')
%n = str2num(N);
f=zeros(size(x));
for i=1:n
t=(-1)^(i-1)*x.^(2*i-1)/factorial(2*i-1);
f=f+t;
plot(x,f,sz(i),'LineWidth',2)
axis([-10 10 -10 10])
pause(1.5)
hold on
n=n+1;
end
function exit_Callback(hObject, eventdata, handles)
close
THE SECOND GUI
function varargout = guzu(varargin)
gui_Singleton = 1;
gui_State = struct('gui_Name', mfilename, ...
'gui_Singleton', gui_Singleton, ...
'gui_OpeningFcn', #guzu_OpeningFcn, ...
'gui_OutputFcn', #guzu_OutputFcn, ...
'gui_LayoutFcn', [] , ...
'gui_Callback', []);
if nargin && ischar(varargin{1})
gui_State.gui_Callback = str2func(varargin{1});
end
if nargout
[varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});
else
gui_mainfcn(gui_State, varargin{:});
end
function guzu_OpeningFcn(hObject, eventdata, handles, varargin)
handles.output = hObject;
guidata(hObject, handles);
function varargout = guzu_OutputFcn(hObject, eventdata, handles)
varargout{1} = handles.output;
function edit1_Callback(hObject, eventdata, handles)
p = str2double(get(hObject,'String')) %I want to return this 'p' to the main gui
close
function edit1_CreateFcn(hObject, eventdata, handles)
if ispc && isequal(get(hObject,'BackgroundColor'), get(0,'defaultUicontrolBackgroundColor'))
set(hObject,'BackgroundColor','white');
end

Answer 1

This kind of simple user input is easy to accomplish using the inputdlg function, without the need to create a separate GUI - here's an example
inputTitle = 'Input Required';
inputPrompt = 'Enter a value for ''p'':';
userInput = inputdlg(inputTitle, inputPrompt);
if isempty(userInput)
% User cancelled
return;
else
p = userInput{1}; % userInput is a cell array
% Do something with p
end
It may be that the example you provided is a very minimal version of your end-goal for the second UI, so this may not be appropriate (though note that the inputdlg function is capable of some more complex behaviour - see the documentation). If you wish to continue using your separate UI, then you have to make a couple of modifications
%%% Add this line to the end of OpeningFcn
uiwait;
%%% Modify OutputFcn to have the following code:
varargout{1} = str2double(get(handles.edit1, 'String'));
% The figure can be deleted now
% NOTE: You have to change this to the name of your figure,
% if it's not called figure1
delete(handles.figure1);
%%% Add the CloseRequestFcn callback and put this code in it
if isequal(get(hObject, 'waitstatus'), 'waiting')
% The GUI is still in UIWAIT, us UIRESUME
uiresume(hObject);
else
% The GUI is no longer waiting, just close it
delete(hObject);
end
Most of the above is directly copied from here. You can also remove the call to uiwait from FoProgram.
