TextField - relu91/nifty-gui GitHub Wiki
The TextField control allows input of text. The creation is dynamically possible from Java with the TextFieldBuilder class as well as from XML using Niftys Standard <control></control> Tag. The length of the input field can be restricted and the actual input can be hidden with an optional password char if necessary.
The following table describes all TextField parameters.
| Name | Datatype | Default | Description |
| text | String | "" | The initial text that the TextField contains. |
| maxLength | Integer | (not set) | The maximum length of characters that this TextField can contain. If not set or if this value is -1 then no restriction is applied. |
| passwordChar | Character | (not set) | If set then each character of the TextField will be replaced by the given char. If you use '*' for this you can get a typical password input field. |
The TextField control supports EventBus notification for any changes applied to the text. Whenever the text content of the TextField changes a TextFieldChangedEvent is published using the id of the TextField as the Topic for the Event.
// Using the builder pattern
control(new TextFieldBuilder("passwordCharTextField", "*") {{ // init with the text "*"
maxLength(1); // force only a single character input
width("20px");
}});<!-- simple password textfield example. please note: event notification requires an id -->
<control name="textfield" maxLength="20" passwordChar="*" />
