Component | Lock Aspect Ratio

The aspect ratio of a component is the ratio of its width to its height. When this menu item is selected, the aspect ratio of the highlighted component is locked. If the width (or height) of the component is changed, the height (or width) will automatically be changed to keep the aspect ratio constant. The lock on the aspect ratio can be temporarily overridden by holding down the Ctrl key, while dragging the boundaries of a component to resize it.

When enabled, a check mark appears beside this item in the Component menu. Select the menu item to toggle the check mark off or on. By default, Lock Aspect Ratio is off for all components.
