Adding callbacks to JFileChooser in embedded GUI

2 views (last 30 days)
Hi, I'm trying to build a dialog with an embedded file open dialog (see code below as starting point). I'm having trouble working out how to add callbacks (listerners) to the open and cancel buttons.
I want to add a number of checkboxes to the right hand side - and if the user selects a file/files and clicks open then I want to perform specific tasks - any help on how I can do this much apprecaited.
import javax.swing.JFileChooser;
d = dialog('windowstyle', 'normal', 'position', [0 0 750 400] );
centerfig ( d )
set ( d, 'visible', 'on' );
[jPanel,hPanel] = javacomponent(javax.swing.JPanel, [], d);
hControl = uicontrol('style','checkbox', 'parent',d,'string','click me', 'units','normalized','position', [0.85 0.8 0.2 0.2]);
set(hPanel, 'units','normalized','position',[0 0 0.8 1.0]);
jchooser = javaObjectEDT('javax.swing.JFileChooser', pwd );
%%Show the actual dialog
% status = jchooser.showOpenDialog([]);

You could install callbacks to log the state of the buttons in MATLAB so these would be available after you click 'Open' and return to MATLAB.
hControl = uicontrol('style','checkbox', 'parent',d,'string','click me', 'callback', 'disp(''State Change'')','units','normalized','position', [0.85 0.8 0.2 0.2]);
'disp(''State Change'')'
with a callback.

1. How to obtain which of the actions was performed?
2. How to change the jchooser to be a save dialog rather than opendialog
