Examples

Create App

When you open App Designer, the App Designer Start Page appears.

To create an app, select one of the app templates from the Apps section of the Start Page:

• Blank App — Create a blank app file.

• 2-Panel App with Auto-Reflow — Create an app with two panels that automatically resize and reflow to fit different device screen sizes.

• 3-Panel App with Auto-Reflow — Create an app with three panels that automatically resize and reflow to fit different device screen sizes.

A new file named app1.mlapp opens in App Designer. The app1.mlapp file does not appear in the MATLAB Current Folder browser until you save it.

Create Custom UI Component

Create a custom UI component that you can use in your apps or share with others.

When you open App Designer, the App Designer Start Page appears.

To create a custom UI component, select one of the templates from the Custom UI Components section of the Start Page:

• Blank Component — Create a blank custom UI component file.

• Blank Component with Grid Layout — Create a custom UI component with a grid layout that manages the UI component layout and size in an app.

A new file named comp1.mlapp opens in App Designer. The comp1.mlapp file does not appear in the MATLAB Current Folder browser until you save it.

Open Existing App File

Open an existing app created in App Designer by clicking the Open button on the App Designer Start Page. Alternatively, if you have recently opened an app, click the app name in the Recent Files section to reopen the file.

Package and Share App

After creating an app, you can package it into a single installer file that you can easily share with others.

With the app open in App Designer, select the Designer tab. Then select Share > MATLAB App.

Fill out the Package App dialog box, then click Package to create an installation file to share your app with your users.
