TextField (libGDX Core 1.6.3 API)

java.lang.Object
- com.badlogic.gdx.scenes.scene2d.Actor
- - com.badlogic.gdx.scenes.scene2d.ui.Widget
  - - com.badlogic.gdx.scenes.scene2d.ui.TextField

All Implemented Interfaces:

Disableable, Layout

Direct Known Subclasses:

TextArea
```
public class TextField
extends Widget
implements Disableable
```
A single-line text input field.
The preferred height of a text field is the height of the TextField.TextFieldStyle.font and TextField.TextFieldStyle.background. The preferred width of a text field is 150, a relatively arbitrary size.
The text field will copy the currently selected text when ctrl+c is pressed, and paste any text in the clipboard when ctrl+v is pressed. Clipboard functionality is provided via the Clipboard interface. Currently there are two standard implementations, one for the desktop and one for Android. The Android clipboard is a stub, as copy & pasting on Android is not supported yet.
The text field allows you to specify an TextField.OnscreenKeyboard for displaying a softkeyboard and piping all key events generated by the keyboard to the text field. There are two standard implementations, one for the desktop and one for Android. The desktop keyboard is a stub, as a softkeyboard is not needed on the desktop. The Android TextField.OnscreenKeyboard implementation will bring up the default IME.
