Creating Graphical User Interfaces

User-Specified Resize Operation

You can create GUIs that accommodate resizing, while at the same time maintain the appearance and usability of your original design by programming the figure ResizeFcn callback routine. This callback routine essentially recalculates the size and position of each component based on the new figure size.

This approach to handling figure resizing is used most typically in GUI-based applications that require user interaction on an ongoing basis. Such an application might contain axes for displaying data and various components whose position and size are critical to the successful use of the interface.

Property Settings

GUIDE sets the following properties to implement this style of GUI:

• Units properties of the figure, axes, and uicontrols should generally be set to characters so the GUI displays at the correct size at runtime.
• Resize figure property set to on (the default).
• ResizeFcn figure property requires a callback routine to handle resizing.

See The Address Book Resize Function for an example of a user-written resize function.
