Adding callbacks to JFileChooser in embedded GUI

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([]);
jPanel.add(jchooser)

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]);

Replace

'disp(''State Change'')'

with a callback.

The problem I'm having is adding a callback to the Open and/or cancel buttons - not obtaining the state of the checkboxes.

Thanks anyway.

@Robert

Both buttons fire ActionPerformed events so

set(jchooser,'ActionPerformedCallback', 'disp(''Action'')')

Edit: For future reference, that would be better as:

set(handle(jchooser, 'callbackproperties'),'ActionPerformedCallback', 'disp(''Action'')')

to reduce memory leaks and MATLAB warnings on recent versions.

Malcolm,

Thanks for this 1 have 2 further questions.

1. How to obtain which of the actions was performed?

2. How to change the jchooser to be a save dialog rather than opendialog

Thanks
