MATLAB Creating Graphical User Interfaces

pos_size = get(handles.figure1,'Position');

% Call modaldlg with the argument 'Position'.

user_response = modaldlg('Title','Confirm Close');

switch user_response

case 'No'

% take no action

case 'Yes'

% Prepare to close application window

delete(handles.figure1)

end

When the user clicks the Close button in the closedlg window, the

pushbutton1_Callback function executes this command:

user_response = modaldlg('Title','Confirm Close');

Recall that the modaldlg function is coded in the other program file, modaldlg.m.

That function displays a second window: the Confirm Close dialog box. The return

argument, user_response, is the user’s selection from that dialog box.

The switch command decides whether to close the first window (modaldlg) based on

the user’s selection.
