The GUIDE environment will be removed in a future release. After GUIDE is removed, existing GUIDE apps will continue to run in MATLAB® but they will not be editable in GUIDE.
To continue editing an existing GUIDE app, see GUIDE Migration Strategies for information on how to help maintain compatibility of the app with future MATLAB releases. To create new apps, use App Designer instead.
By default, user interface controls (uicontrols) use the default font for the platform on which they are running. For example, when displaying your UI on PCs, uicontrols use MS San Serif. When your program runs on a different platform, it uses that computer's default font. This provides a consistent look with respect to your UI and other applications.
If you have set the
FontName property to a named font and want to
return to the default value, you can set the property to
default. This ensures that the software
uses the system default at run-time.
You can use the Property Inspector to set this property:
As an alternative, use the
set command to set the property in the code
file. For example, if there is a push button in your UI and its
handle is stored in the
pushbutton1 field of the
handles structure, then the

If you want to use a fixed-width font for a user interface control,

This special identifier ensures that your UI uses the standard fixed-width
font for the target platform.
You can find the name of the fixed-width font that is used on
a given platform by querying the root
You can specify an actual font name (such as Times or Courier)
FontName property. However, doing so may
cause your UI to not look as you intended when run on a different
computer. If the target computer does not have the specified font,
it will substitute another font that may not look good in your UI
or may not be the standard font used for UIs on that system. Also,
different versions of the same named font may have different size
requirements for a given set of characters.
The default component background color is the standard system background color on which the UI is displaying. This color varies on different computer systems, e.g., the standard shade of gray on the PC differs from that on UNIX® system, and may not match the default UI background color.
If you use the default component background color, you can use that same color as the background color for your UI. This provides a consistent look with respect to your UI and other applications. To do this in GUIDE, check Options > Use system color scheme for background on the Layout Editor Tools menu.
This option is available only if you first select the Generate FIG-file and MATLAB File option.
Cross-platform compatible UIs should look correct on computers
having different screen sizes and resolutions. Since the size of a
pixel can vary on different computer displays, using the default figure
not produce a UI that looks the same on all platforms.
For this reason, GUIDE defaults the

Character units are defined by characters from the default system
font. The width of a character unit equals the width of the letter
the system font. The height of a character unit is the distance between
the baselines of two lines of text. Note that character units are

At, times it might be convenient to use other units, such as

GUIDE does not automatically adjust component units if you
modify the figure's
