Creating Graphical User Interfaces

The Confirmation Dialog Application M-file

The confirmation dialog has its own application M-file, which the main application calls to launch the dialog. This M-file can be called in three ways:

• No arguments - launch the dialog and wait for user input.
• One numeric argument - launch the dialog and place it at the location specified in the two-element vector.
• Four arguments - call the Yes or No button callback with the usual arguments (h,eventdata,handles,varargin).

With each calling syntax, the M-file returns a string output argument indicating the user response.

The application M-file performs various operations, which are described in the following sections:

• Launch the dialog
• Specify the location of the dialog
• Wait for user response
• Execute a callback
• Define the Yes button and No button callbacks
