Pass data between gui's matlab

问题

I have two gui's one is main gui and other is sub gui. In opening function of main gui i used open('subgui.fig'); to open sub gui. Main consists of 5 edit box and one pushbutton. After pressing pushbutton the data in those 5 edit boxes should be passed to sub gui and main gui should close. Please any one help me to do this.

Let us take a simple case of one editbox and one pusbutton in main GUI and one editbox in sub GUI that will get value from the editbox in main GUI. One can easily extend this to as many editboxes as needed. The basic medium of data storage and retrieval would be a global structure data1.

For the sake of understanding the codes, let us take the following assumptions -

Main GUI is named as main_gui.m and thus has an associated main_gui.fig from GUIDE. Main GUI's figure has the tag main_gui_figure.
Sub GUI is named as sub_gui.m and thus has an associated sub_gui.fig from GUIDE.

Edits to be made in main_gui.m

Inside editbox's callback, add this -

global data1;

%%// Field in data1 to store the string in editbox from main GUI
data1.main_gui.edit1val = get(hObject,'String');

Inside the pushbutton's callback, add this right before it's return -

global data1;
sub_gui;
delete(handles.main_gui_figure);

Edits to be made in sub_gui.m

Inside sub_gui_OpeningFcn, add this -

global data1;
set(handles.edit1,'String',data1.main_gui.edit1val);%%// Tag of editbox in sub-gui is edit1

Hope this works out for you! Let us know!

There are probably more than one ways to achieve this. But one of the approaches is to define a function that takes two input arguments: 1) handles to the destination figure and 2) whatever data from the source figure.

The following psuedo code doesn't necessarily run in MATLAB, but it gives the basic idea:

function takeAction(uihdls, data)
  set(0, 'CurrentFigure', uihdls.fig); % uihdls.fig is the handle of the destination figure.

  set(gcf, 'CurrentAxes', uihdls.aexs1); % axes1 is inside fig
  plot(data.x, data.y); % Do some plotting

  set(uihdls.editBox, 'String', data.string); % Modify some property of a control inside fig.

  key_Callback(uihdls.fig, data.keyData); % Call a callback function of the destination figure

return

This function can be called by the source figure whenever it is ready to do so.
