2 Creating a GUI

2-22

The following figure shows how the GUI now looks when it first displays.

Adding Code to the Callbacks

When the GUI is completed and running, and a user clicks a user interface

control, such as a push button, MATLAB executes the callback specified by the

component’s

Callback property. In the example, the name of the Surf push

button callback is

surf_pushbutton_Callback. For information about the

naming of callbacks see “The Tag Property” on page 2-14.

This section describes how to add the code for the callbacks.

Push Button Callbacks

Each of the push buttons creates a different type of plot using the data specified

by the current selection in the pop-up menu. Their callbacks get data from the

handles structure and then plot it. To add code to the surf push button

callback, click

surf_pushbutton_Callback in the callback pop-up menu.
