Creating Graphical User Interfaces

Application Techniques

Example Applications

This section contains a series of examples that illustrate techniques that are useful for implemented GUIs. Each example provides a link to the actual GUI in the GUIDE Layout Editor and a link to the application M-file displayed in the MATLAB editor.

• Launching a Dialog to Confirm an Operation - display a second figure from your GUI to ask a question. This modal dialog blocks MATLAB until the user responds, then returns the answer to the calling GUI.
• List Box Directory Reader - list the contents of a directory, navigate to other directories, and define what command to execute when users double-click on a given type of file.
• Accessing Workspace Variables from a List Box - list variables in the base MATLAB workspace from a GUI and plot them. This example illustrates multiple item selection and executing commands in a different workspace.
• A GUI to Set Simulink Model Parameters - set parameters in a Simulink model, save and plot the data, and implement a help button.
• An Address Book Reader - read data from MAT-files, edit and save the data, manage GUI data using the handles structure.
