| Creating Graphical User Interfaces | |
Application data provides a way for applications to save and retrieve data stored with the GUI. This technique enables you to create what is essentially a user-defined property for an object. You can use this property to store data.
The GUI M-file uses application data to store the handles structure.
When using the GUIDE-generated M-file, it is simpler to use guidata than to access application data directly.
