If a component has a label, and you change the label text, the name of the component in
the Component Browser changes to match that text. You can customize the name of the

Customizing Components
You can customize the appearance of a component by selecting it and then editing its
properties in the Inspector tab of the Component Browser. For example, from this tab
you can change the alignment of the text that displays on a button.
Some properties control the behavior of the component. For example, you can change the
range of values that a numeric edit field accepts by changing the Limits property.
