Function Handle Callbacks

Handle Graphics objects have a number of properties for which you can define callback functions. When a specific event occurs (e.g., a user clicks a push button or deletes a figure), the corresponding callback function executes. You can specify the value of a callback property as a

• String that is a MATLAB command or the name of an M-file
• Cell array of strings
• Function handle or a cell array containing a function handle and additional arguments

The following sections illustrate how to define function handle callbacks for Handle Graphics objects.

• Function Handle Syntax describes how to define a function handle callback.
• Why Use Function Handle Callbacks provides information on the advantages of using function handle callbacks.
• Example -- Using Function Handles in GUIs shows how to create a simple GUI that uses function handle callbacks.

For general information on function handles, see the function handle reference page.
