7 Saving and Running the GUI

7-10

Running a GUI

Generally, you run your GUI by executing the M-file that GUIDE generates.

This M-file contains the commands to load the GUI and provides a framework

for the component callbacks. See “GUI Files: An Overview” on page 8-5 for

more information about the M-file.

When you execute the M-file, a fully functional copy of the GUI displays on the

screen. You can run a GUI:

• “From the GUIDE Layout Editor” on page 7-10

• “From the Command Line” on page 7-10

• “From an M-file Script” on page 7-11

Note You can display an inactive copy of the GUI figure using the openfig,

open, or hgload command. These commands load FIG-files into the MATLAB

workspace. Note that the displayed GUI is not active.

From the GUIDE Layout Editor

Run your GUI from the GUIDE layout Editor by:

• Clicking the Run icon on the Layout Editor toolbar

• Selecting

Run from the Tools menu

In either case, GUIDE saves the GUI files before activating the GUI and opens

the GUI M-file in your default editor. See “Saving a GUI” on page 7-5 for

information about this process. See “GUI Files: An Overview” on page 8-5 for

more information about M-files.

From the Command Line

Run your GUI from the command line by entering the name of its M-file. For

example, if your GUI M-file is

mygui.m, type

mygui

at the command line. If the M-file does not reside on your MATLAB path or in

your current MATLAB directory, you must also specify the path.
