Overview
The Jewel TextInput implements the jewel control for single-line text field. It dispatches a change event when the user input text.
For multi line text input control see TextArea
Example of use
In MXML declare a TextInput
like this:
<j:TextInput/>
In ActionScript we can do the same in the following way:
var textInput:TextInput = new TextInput();
parent.addElement(textInput);
where parent
is the container where the control will be added.
Here is an example of the default text input:
Relevant Properties and Methods
Check the Reference of org.apache.royale.jewel.TextInput for a more detailed list of properties and methods.
Properties
PROPERTY | Type | Description |
---|---|---|
text | String | The text inside the text field. |
html | String | The html text inside the text field. |
Methods
None.
Relevant Events
The TextInput
has change event of type org.apache.royale.events.Event. This event is dispatched when text in the control changes through user input. Notice that programatic changes will not trigger this event.
You can attach callback listeners to the change event in MXML as follows:
<j:TextInput change="changeHandler(event)"/>
the change event will use the changeHandler
callback function you provide in ActionScript:
<fx:Script>
<![CDATA[
private function changeHandler(event:Event):void {
trace("new text is: " + event.target.text);
}
]]>
</fx:Script>
When the user introduce text in the input field, the message “new text is: “ plus the text introduced will appear in the console log.
In ActionScript we can add an event handler this way:
var textInput:TextInput = new TextInput();
textInput.addEventListener('change', changeHandler);
parent.addElement(textInput);
Relevant Beads
Unlike other components in Royale, the Jewel TextInput
does not have beads for View, Controller or Model in the Javascript platform.
On the other hand, you can add to it beads specialy crafted for this control or other common Jewel control beads (shared with other controls) to provide more functionality.
