App Designer Preferences
You can set App Designer preferences in the MATLAB® Preferences dialog box. To open the dialog box, click
Preferences in the MATLAB Toolstrip. Then, select App Designer in the left pane.
This table describes each option in the right pane.
| Option | Description |
|---|---|
| Show grid with interval | When selected, App Designer overlays a grid onto the canvas as an alignment aide. You can change the grid spacing to a specific number of pixels. The default spacing is 10. |
| Snap to grid | When selected, the upper left corner of a component always snaps to the intersection of two grid lines whenever you resize or move the component on the canvas. |
| Show alignment hints | When selected, App Designer displays alignment hints as you resize or move a component on the canvas. |
| Show resizing hints | When selected, App Designer displays the size of a component as you resize it on the canvas. |
| Font Size | You can change the font size that displays in App Designer Code View. The font size can range from 14–48 pixels. The default font size is 14 pixels. |
| Enable app coding alerts | When selected, App Designer flags coding problems in the editor as you write code. |
| Include component labels in Component Browser | When selected, labels included with components (such as edit fields) appear as separate items in the Component Browser. When this item is not selected, those labels do not appear in the Component Browser. |
| Number of entries (most recently used file list) | This number specifies how many of the most recently accessed apps appear under the Recent Files section of the Open menu in the Designer tab. |
| Automatic File Changes | When selected, App Designer automatically saves changes to an app when you click away from it to switch between apps or to bring another window into focus. If an app has not already been saved at least once, autosave has no effect. |
