you want to pass data between the gui??

[Hossein Saberi]

yes i can find this

function pushbutton1_Callback(hObject, eventdata, handles)
 % get the handle of Gui1
 h = findobj('Tag','Gui1');
 % if exists (not empty)
 if ~isempty(h)
    % get handles and other user-defined data associated to Gui1
    g1data = guidata(h);
    % maybe you want to set the text in Gui2 with that from Gui1
    set(handles.text1,'String',get(g1data.edit1,'String'));
    % maybe you want to get some data that was saved to the Gui1 app
    x = getappdata(h,'x');
 end

A specific question is more efficient than "I don't understand how it works". The code example contains useful comments already.

 % get the handle of Gui1
 h = findobj('Tag','Gui1'); 

Is this clear so far? Each GUI element, e.g. a figure, has a unique "handle", which can be used to access the object. Instead of seaching all GUI elements, e.g. all buttons, lines and menu entries, it is faster to restrict the search to the wanted object:

 h = findob(allchild(0), 'flat', 'Tag', 'Gui1'); 

Now only figures are searched.

 % if exists (not empty)
 if ~isempty(h)

A matching figure was found.

    % get handles and other user-defined data associated to Gui1
    g1data = guidata(h);

Now you can access the handles struct of the found figure. Do not get confused by the name "handles". It does contain handles of the GUI elements created by GUIDE, but you can store anything in this struct also.

Now the callback can access all elements of the figure with the tag 'Gui1', e.g. getting the values of toggle-buttons or draw in existing axes.

Search in this forum for "share data between callbacks". This works for callbacks of different figures also.

Thank you for your help jan

I used 8 guide because of the lack of space in guide, and now I want to put all the information (e.g. position , ...) in one m-file

do u think can i call this information with this method and then use this?

guidata(hObject, ...)
