12 Examples of GUIs Created Programmatically

12-28

2 Data creation. Because the example uses nested functions, defining this

data at the top level makes the data accessible to all functions without

having to pass them as arguments.

3 Command line input processing.

4 GUI figure and component creation.

5 GUI initialization.

6 Return output if it is requested.

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

are subfunctions of the

colorPalette function and so have access to the

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

to be passed as arguments.

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

colorPalette 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.

GUI Programming Techniques

This topic explains the following GUI programming techniques as they are

used in the creation of the colorPalette.

• “Passing Input Arguments to a GUI” on page 12-29

• “Passing Output to a Caller on Returning” on page 12-30

• “Sharing Data Between Two GUIs” on page 12-30

See “Icon Editor” on page 12-33 for additional examples of these and other

programming techniques.
