userInput events


Creates a single-line text field for text input.

Native text fields can listen for userInput events (see example).

Native text fields can display optional placeholder text (nil by default). This can provide a "hint" as to what the user should enter in the field. If set, the placeholder string is displayed using the same style information (except the text color). The placeholder does not appear once actual text has been input into the field and it does not currently participate in determining the size of the text field.


Native text fields are only available in device builds, the Xcode Simulator, and in the Corona Mac Simulator.

Because native text fields are not part of the OpenGL canvas, they do not obey the Corona display object hierarchy. For example, while they can be manipulated using display object methods, they always appear above normal display objects, and cannot be inserted into display groups.

Also, they do not inherit display group properties like isVisible, x, y, rotation, and alpha. If you need to set display properties on native objects, apply them to the objects directly.

To remove a native text field from the display, use object:removeSelf().

For multiline text, see native.newTextBox().

The native.setKeyboardFocus() API is used to set and clear the keyboard used for text input.

See the TextField object reference for a complete listing of properties and methods (such as inputType, font, size, and more).


native.newTextField( centerX, centerY, width, height [, listener] )
centerX, centerY (required)

Numbers. The x and y coordinates that correspond to the center of the text field.

width, height (required)

Numbers. Width and height (size) of the text field.

listener (optional)

Listener. Function to respond to keyboard events. It is recommended you do not use this argument and instead add a "userInput" event listener to the text field object. See userInput for more information.
