You can change the size of a TextInput instance while authoring and at run time. While authoring, select the component on the Stage and use the Free Transform tool or any of the Modify > Transform commands. At run time, use the setSize() method or applicable properties of the TextInput class, such as height, width, scaleX, and scaleY.
When a TextInput component is resized, the border is resized to the new bounding box. The TextInput component doesn't use scroll bars, but the insertion point scrolls automatically as the user interacts with the text. The text field is then resized within the remaining area; there are no fixed-size elements in a TextInput component. If the TextInput component is too small to display the text, the text is clipped.
