12 Examples of GUIs Created Programmatically

12-38

3 GUI figure and component creation.

4 Command line input processing.

5 GUI initialization.

6 Block execution of the program until the GUI user clicks OK or Cancel.

7 Return output if requested.

8 Callback definitions. These callbacks, which service the GUI components,

are subfunctions of the

iconEditor function and so have access to the data

and component handles created at the top level, without their having to be

passed as arguments.

9 Helper function definitions. These helper functions are subfunctions of the

iconEditor function and so have access to the data and component handles

created at the top level, without their having to be passed as arguments.

Note For information about using nested functions, see Nested Functions in

the MATLAB documentation.
